LATEST DEVELOPMENTS
Byotrol plc ("Byotrol" or the "Company"), the leading anti-microbial technology
company is pleased to be able to provide an update on recent developments across
the business.
Agricultural Sector - Contract
The Company has secured a contract to supply The Active Group, a UK based
producer and distributor of agricultural products, with a range of hoof and teat
care products containing Byotrol technology in both concentrate and pre-mix form
for use by livestock farmers. Products to the value of £250,000 are to be
delivered in March 2008 and the annual call off is expected to be around £1
million in the first year.
The Directors of Byotrol believe the dairy cattle sector will be an important
market for the Company and expenditure on sanitising products is estimated to be
worth in excess of £35 million per annum in the UK, with equally significant
opportunities in Western Europe and North America.
The Company's teat and hoof care products were launched at one of the UK's
leading agricultural events, the Royal Bath and West of England Dairy Show, in
January this year.
Food Sector - Marks and Spencer ("M&S") Accreditation and Heinz Order
The Company is very pleased to report that M&S has approved Byosan as an
Approved Terminal Disinfectant for use within M&S's Food Manufacturing Supply
Chain. Accordingly, Byotrol is now approved to supply organisations that process
and manufacture food products on behalf of M&S.
Approval was granted following an eight month, three stage project involving
initial laboratory verification of the technology by the Campden and Chorleywood
Food Research Association followed by a period of commercial validation
conducted by Pennine Foods (part of Northern Foods). Hygiene, technical and
final commercial validation was conducted in conjunction with Pennine Foods.
In the Director's opinion the approval with M&S opens up potentially significant
sales opportunities following the approval with one of the UK's most reputable
food retailers. It also opens up sales opportunities within Northern Foods, as a
result of the work conducted with Pennine Foods.
The Company has also secured its first order to supply food manufacturer H J
Heinz with Byotrol technology in one of its facilities in Cumbria. The initial
order follows extensive evaluation conducted by H J Heinz to establish the
efficacy of the Byotrol technology. Studies of Byotrol products are being
conducted at other Heinz sites.
Healthcare Sector - Care UK Deployment Complete and Pre-School Care Order
The Company's health distribution partner, Synergy Healthcare, has completed the
installation of more than 4,000 hand dispensers that use hand hygiene products
containing Byotrol technology into Care UK, a leading independent provider of
health and social care service solutions. The completion of this installation
will lead to an annual ongoing provision of product to Care UK.
The Company has also secured an initial order for £30,000 of product to be
supplied for use in the pre-school and playgroup sectors where Byotrol
technology is being used under the Toyguard brand to enable playgroup operators
to clean equipment and toys used in the pre-school setting.
Consumer Products
Byotrol's joint venture, Byotrol Consumer Products limited, set up with leading
innovation company What If, continues to make strong progress with a number of
leading companies in the target consumer goods sectors and the business plan for
this joint venture is in line with the original timescales set out at the time
of launch.
Commenting on these developments Stephen Falder, Deputy Chairman of Byotrol plc
said:- "In the food sector we have set out to secure accreditation and orders at
the very highest level with three of the UK's leading food manufacturers. These
pave the way for sales right across the food industry supply chain.
"We are now starting to demonstrate commercial returns across a number of
sectors and are looking to build on these successes in the months ahead."

Transparency Rules, the total number of ordinary shares of 0.25p of Byotrol in

Transparency Rules.

BYOTROL plc SIGNS JOINT VENTURE WITH CONSUMER INNOVATION EXPERTS
The Directors of Byotrol plc ('Byotrol' or the 'Company') are pleased to
announce the signing of a joint venture with What If Ventures, the investment
arm of What If Holdings Ltd, the holding company of the world's largest
independent consumer innovation company.
The joint venture will be called Byotrol Consumer Products Limited ('BCP') and
will provide the vehicle through which the Company will pursue opportunities for
its anti-microbial technology in global consumer markets. BCP will pursue a
similar strategy to Byotrol, seeking to exploit its technology by entering
licence agreements with leading Fast Moving Consumer Goods companies ('FMCG').
The Board recognises that the skills, expense and timeframes required in
launching new consumer products require a partner with a proven track record in
the FMCG sector. What If Ventures and its group have that track record, as well
as leading-edge global consumer insight skills, new product development
expertise and access to the world's major consumer product businesses.
In the opinion of the Directors, BCP represents the most appropriate structure
to maximise the significant opportunity presented by the consumer marketplace.
The Board expects the combination of Byotrol and What If Ventures to short cut
the often lengthy and expensive new product development process within FMCG
businesses and bring the Byotrol anti-microbial technology to the largest
possible audience at the fastest possible pace.
Byotrol Consumer Products Limited
Background
Having identified What If Ventures as the most appropriate partner, the Board
has worked closely with the What If Ventures team since the beginning of 2007.
Considerable work has been undertaken ahead of the formation of the joint
venture in order to maximise the opportunities available to it from today
onwards.
During 2007, the joint venture partners have invested considerable time, money
and resource in planning BCP, including strengthening the patent framework,
developing and testing products, developing consumer insights and consumer
propositions, market scoping and target licensee development.
More specifically, focus groups were conducted in the United Kingdom, United
States, Europe, China and India. Within these groups the response to the
Byotrol anti-microbial technology was encouraging.
The market opportunity
Based on initial research carried out by BCP, the Byotrol anti-microbial
technology is relevant to several multi-billion dollar global consumer markets.
There are a number of specific applications within the consumer marketplace that
BCP has identified, where there is the potential to add value to products
through the addition of Byotrol's technology.
Strategy
The strategy pursued by BCP will be similar to that already in place within
Byotrol, in that licensees will be sought from amongst the leading global FMCG
companies. It is expected that BCP will receive principally a mixture of
initial fees and on-going royalties where the Byotrol technology is used.
In the next two years, BCP will focus on concluding two major types of licensee
opportunities. In particular, BCP will seek to partner with a global FMCG
business and will also examine opportunities with companies which have specific
niche opportunities whether on a regional or global basis.
Inevitably, each potential licensee will require time to assess the opportunity
whilst BCP will aim to ensure the optimum combination of licensees. In FMCG
businesses, new product launches can typically take many years from inception to
profitability. The Directors believe however that the addition of What If
Ventures' consumer insight, innovation expertise and high level corporate access
will have a significant impact on the time taken to introduce product to the
market.
The board of BCP currently expects that the company will break even within
approximately two years. However it is not anticipated that the company's start
up costs will be significant ahead of that time.
The joint venture
An agreement has today been signed that establishes Byotrol Consumer Products
Limited as a 50:50 joint venture between Byotrol and What If Ventures'
investment vehicle, What If Innovation Capital Nominees Ltd ('WIICN'). Both
companies have committed to invest £250,000 during the first year of operation.
Initially, BCP will draw directly upon resources and expertise within Byotrol
and What If Ventures before recruiting the appropriate longer term management
team in due course.
The board of Byotrol Consumer Products will comprise David McRobbie (Chief
Executive, Byotrol), Stephen Falder (Deputy Chairman, Byotrol), Richard Bell
(Finance Director, Byotrol), David Traynor (Director, WIICN), David Allan
(Director, WIICN) and Julia Hoare (Director and Company Secretary, WIICN). In
addition, BCP will be able top draw upon the knowledge and expertise of senior
advisers with backgrounds in FMCG operations.
Byotrol plc Chief Executive David McRobbie said: 'This joint venture will allow
us to fast track our technology to the consumer market place. What If Ventures
and its group's proven track record working with FMCG companies, its network of
contacts, its consumer knowledge and its insight and marketing expertise are a
perfect fit with our scientific and technical innovation skills.
'For Byotrol alone, launching a consumer brand from scratch would be a massive
financial undertaking with significant risk attached. By partnering with What If
Ventures, we are aiming to capture a substantial amount of market share without
the risk or cost associated with a conventional entry into the consumer market
place.
Importantly, the establishment of this joint venture also allows us to maintain
a strong focus on our core business in the healthcare, food, agriculture and
industry sectors.'
David Allan of What If Ventures added: 'We believe Byotrol is a very significant
technology which will deliver real innovation and significant benefits to
consumers. Our initial research show the technology has the potential to cross a
number of hygiene markets in home and personal care from anti bacterial
protection of the kitchen and bathroom to skin care and pet care. What If
Ventures is ideally positioned to help develop the consumer business and help
introduce Byotrol to some of the world's leading FMCG businesses.'

BYOTROL NEW GLOBAL CONTRACT ANNOUNCEMENT
The Directors of Byotrol plc (the 'Company') are pleased to be able to report a
new global contract that has been secured by the Company.
The Company has worked in partnership to develop a range of products
incorporating Byotrol(R) technology for Fellowes Inc, a leading global provider
of office accessories and business machines.
As a global provider, Fellowes has access to a wide range of disinfectant
technologies and chose Byotrol for its residual efficacy, ultra low toxicity
profile and broadband action against a wide range of micro-organisms.
Fellowes is launching the Virashield(TM) range of products containing Byotrol
across Europe with a global launch planned in the near future. The range, which
includes wipes and hand protection foam, is designed to help combat the spread
of infections in the workplace.
Virashield(TM) offers both residual efficacy of
up to seven days coupled with broad spectrum capability against a wide range of
organisms including viruses such as influenza and avian flu and bacteria
including E.coli. Research has shown that a typical office desk harbours up to
400 times more bacteria than a typical toilet seat and the residual efficacy
offered by the Virashield range containing Byotrol will help office workers
combat this real and growing risk of infection.
The Virashield(TM) range has been extensively tested by both Byotrol and
Fellowes and the tests have proven the product's efficacy for up to seven days
following application. The range can both remove microbes from surfaces in an
office environment and keep the surface microbially clean for this period of
time.
Byotrol plc Chief Executive David McRobbie said, 'We are delighted to have
secured our first contract that will make Byotrol available on a global basis
and that a company the size of Fellowes chose Byotrol as its worldwide strategic
partner for this key product launch. There is growing awareness that
micro-organisms are not just an issue in hospitals and specialist environments
and that effective cleaning regimes have a role in a wider range of settings.'
Headquartered in Illinois, USA with subsidiaries in Canada, Benelux, France,
Germany, Italy, Poland, Spain, UK, China, Singapore, Japan, Korea and Australia,
they have an extensive distribution & export network reaching over 100
countries. Fellowes employs more than 2,700 people throughout the world and
expects global sales in excess of $700 million this year.

UPDATE ON TRADING AND RESULTS OF INDEPENDENT TRIAL
The Directors of Byotrol plc (the 'Company') are pleased to be able to provide
an update on the recent strong progress made across the group following the end
of its financial year to 31 March 2007 and to report that direct product sales
revenues will be in line with the Directors' expectations and in the last
quarter of the financial year £240,000 of sales orders were delivered.
The Company has made significant progress across all of its target markets in the year to 31 March 2007 and has been successful in attracting a number of new clients with global scale which the Directors believe will generate significant new sales revenue to the Company.
Within the UK industrial medical sector Byotrol is pleased to be able to announce it has recently shipped an order for more than 20,000 litres of Byotrol concentrates which will be used in a speciality medical application.
The Company is also working on a number of new applications for Byotrol where the Directors see significant opportunities for sale of Byotrol. By way of example, a number of leading UK agricultural distributors have recently placed orders with the Company for disinfectant and wipe products containing Byotrol's technology. Similarly in the pet care niche, sales of a range of grooming products containing Byotrol in leading retailer Pets at Home have significantly exceeded projections and the product range was recently recognised as new product of the year by Pets At Home
The Company's ongoing testing and validation programme has also made strong progress and the Directors are pleased to be able to announce the publication of a North American study detailing the positive effects of the Company's Polysphere(R) product in battling multidrug-resistant organisms ('MDROs'). This study has resulted in the participating hospital incorporating Byotrol products into its cleaning regime and this represents a very encouraging step in penetrating the US healthcare market.
The study, carried out by hospital based researchers at Monroe Hospital,
Bloomington, Indiana found that Polysphere(R) provided 'residual disinfecting
properties to surfaces that may become contaminated by MDROs' and that in
particular it was 'effective for up to three (consecutive) days post treatment'.
All surfaces were inoculated using Vancomycin Resistant Enterococcus faecalis ('
VRE') and Methicillin Resistant Staphylococcus Aureus ('MRSA'). The study found
that for three consecutive days no growth of VRE occurred and that growth of
MRSA was so sparse that it 'could be considered no growth'.
The full text of the paper can be found by following this link: here
Commenting on the recent successes Byotrol plc Chief Executive David McRobbie said:'These recent successes demonstrate our ability to commercialise an innovative technology and generate future revenue streams across our target markets. Equally pleasing is the successful study within North America because this validates our technology in another marketplace. Importantly the work at Monroe Hospital demonstrates our ability to establish a trial that proves the efficacy of our technology and to convert that into product sales in the highly demanding US healthcare market.'
The preliminary results for the year ended 31 March 2007 are expected to be
announced in June 2007.

The Board of Byotrol announces today the appointment of Richard William Bell as
part-time Finance Director, with effect from 1 December 2006.

The contract gives Synergy exclusive sales and distribution rights to Byotrol's
technology in the healthcare market. In addition Synergy will market, sell and
distribute Byotrol's Assure product range to the NHS and Byotrol's existing
healthcare customers. In the UK, Synergy will assume responsibility for
supplying products containing Byotrol to Byotrol's existing healthcare users,
Sun Choice Europe Limited and DBM Holdings Ltd.
The agreement commences immediately with the UK market and incorporates options
that will grant similar rights to Synergy for both USA, Europe and the rest of
the world and these are exercisable between February 2007 and February 2008.
The agreement with Synergy demonstrates Byotrol's strategy to deploy its
technology in partnership with leading businesses in its chosen markets.
According to Stephen Falder, Deputy Chairman of Byotrol plc:
Dr Richard Steeves, Chief Executive of Synergy Healthcare, commented:
'The acquisition of the worldwide rights for Byotrol is a major strategic step forward for Synergy. Byotrol is an ideal fit for Synergy and, coupled with AirCleanse will greatly enhance our product offering in the atmospheric decontamination market. This is an area of critical concern to the healthcare market worldwide in order to counteract the ever-increasing threat of hospital
acquired infections.'

The Board of Byotrol plc (the 'Company') is pleased to announce that Charles
Stanley Securities has, on behalf of the Company, completed a placing (the
'Placing') of 8.34 million new Ordinary Shares of 0.25p each (the 'Placing
Shares') at 60 pence per share to raise approximately £4.6 million, net of
expenses.
The funds will be used by the Directors to address an increasing number of
opportunities that have been recently identified in the Company's target markets
of Healthcare, Food Processing and Industrial & Technical.
The Company recently obtained CE Marking status approving Byotrol for sale in
medical and disinfectant products in Europe and approval from the US Environment
Protection Agency for Byotrol to be used as a disinfectant, sanitiser and anti-
microbial product in a broad number of market sectors. As a result the Company
has been approached by several major multinationals interested in gaining access
to the Company's technology and the Company is currently engaged in discussions
with a number of these companies regarding the sale and/or licensing of Byotrol.
It is expected that the placing proceeds will assist the progress of such
discussions.
The Placing Shares will, when issued and fully paid, rank pari passu in all
respects with the existing issued ordinary shares of the Company.
The Placing is not a rights issue or open offer and the Placing Shares will not
be offered generally to Shareholders, whether on a pre-emptive basis or
otherwise. The Directors believe that the considerable extra cost and delay
involved in a rights issue or open offer would not be in the best interests of
the Company in the circumstances.
Richard Bell, a consultant to the Company, has acquired 10,000 Placing Shares,
pursuant to the Placing, and accordingly now owns 10,000 Ordinary Shares in the
Company.
Application has been made for the Placing Shares to be admitted to trading on
AIM and trading in the Placing Shares is expected to commence on Tuesday 7
November 2006. Following the admission of the Placing Shares to trading on AIM,
the Company will have 43,212,849 Ordinary Shares in issue.
Charles Stanley Securities has also placed a further 1,500,000 ordinary shares
on behalf of Mr Ragnar Olaffson, representing 4.30 per cent. of the current
issued share capital, with institutional investors at a price of 60p. Following
this, Mr Olaffson holds 1,298,000 ordinary shares, representing 3.72 per cent.
of the current issued share capital and 3.00 per cent. of the issued share
capital as enlarged by the Placing.
1 November 2006
The Directors of Byotrol plc (the 'Company') are pleased to announce that the
Company has entered into two separate distribution agreements with SunChoice
Europe Limited ('SunChoice') and DBM Holdings Ltd ('DBM') to supply Byotrol's
assure product range into the UK care homes market.
SunChoice distributes an extensive range of over 5000 products to more than
1,000 nursing and residential care homes in the UK. The product range includes
cleaning and janitorial products, medical consumables, uniforms and patient
handling equipment.
SunChoice is wholly owned by Southern Cross Healthcare Group
plc, the largest provider of care homes and long term care beds in the UK, which
operates over 570 care homes, providing more than 28,000 beds and employing
around 33,000 staff.
Based in Edinburgh, DBM supplies products to healthcare and retail markets, with
a particular focus on independent care home operators throughout the UK.
Byotrol's assure range has been specifically developed for the care homes sector
and comprises disinfectant sprays for use in living areas, kitchens and
bathrooms, cleaning and sanitising wipes, and a hand sanitising mousse. The
Company's patented technology has been proven, through extensive testing, to be
effective in eradicating and controlling a wide range of organisms such as MRSA,
c.difficile and e-coli. Byotrol remains active after it has dried, providing
anti-microbial protection for extended periods after application and is able
therefore to tackle the practical problems of odours and spoilage caused by
microbe activity.
Byotrol is not toxic to humans and does not require any specialist equipment or
alteration to existing cleaning regimens to be effective. A further advantage of
Byotrol is also its ultra low alcohol content, compared to competing products,
which means it does not dry or irritate the skin when used as a hand sanitiser
as part of infection control procedures.
The Directors anticipate that the agreements with SunChoice and DBM will make a
significant contribution to the Company's future revenues.
Stephen Falder, Byotrol's Deputy Chairman commented:
'We are delighted to be working with SunChoice and DBM, who will be marketing
our assure product range to a significant number of nursing and residential care
homes in the UK. Byotrol has undergone extensive testing and has been shown to
deliver substantial benefits to both residents and healthcare professionals .'
Barbara Hornby, Managing Director for SunChoice Europe commented:
'Working with Byotrol is a significant move for SunChoice Europe to provide a
leading edge, yet proven solution for infection control. We now have the
opportunity to distribute this innovative technology to care homes across the
UK, helping to combat the risk and spread of MRSA and other harmful
micro-organisms.'
Gary Walsh, Marketing Director for DBM stated:
'The partnership with Byotrol enables DBM to provide truly innovative control
methods which are safe to use, compatible with the material they protect and
also comply with increasingly strict regulatory controls. This ground breaking
anti microbial technology will provide care and nursing homes with a truly
unique method of combating the risk and spread of MRSA and other harmful
micro-organisms in higher risk environments. We also believe that the results of
the recent study at Glasgow Royal Infirmary will have a positive impact on
potential customers.'
