What's New in Fermentation and Biotechnology May/June 2004
Enzymes to the Rescue and How about Antibiotics
There is little to cheer about when reviewing basic fermentation products such as
citric acid, vitamin C, penicillins and other antibiotics. In former years
these products were 'cash cows' governed by economic criteria - predictable
cost of raw material costs, reasonable manufacturing cost below selling price,
hence acceptable return on investment. All this has taken a tumble because of
continuous declining sales prices. Who is responsible for this chaos? The simple
answer is too many players and especially Chinese who don't play this game by any
established rules so that nowadays selling prices have dipped below manufacturing costs.
Fortunately there is less Chinese competition in the enzyme business and as a result
this sector continues to grow at a healthy 6-7% annual rate with stable prices. Over
20 enzymes hich are termed 'industrial' with applications in a wide range of industries
including detergents, starch, dairy, baking, brewing, fruit juice, animal feed, textile,
pulp and paper. In each of these sectors enzymes play a different role: in cheese
they act as coagulants for milk, in starch they hydrolyse the starch polymer to glucose,
in baking they degrade the starch network thereby inhibiting staling, in brewing they
replace malt in the mashing process, in animal feed they degrade phytin in cereals to
generate phosphorus, in textiles, they hydrolyse denim fibre to give a 'washed' appearance.
There are only three significant players in the enzyme business: Novozymes with 46%
market share, Genencor with 20% and DSM with 7%. Smaller players include AB Enzyme,
part Of Associated British Foods [who have just acquired the Burns Philp yeast business],
Amano, Japan as well as several producers for captive usage such as ADM and Henkel.
The health of the enzyme business is underlined by increasing fermentation capacity
installed by the major players all over the world.
So where are the Chinese? Yes they are present in enzymes but somewhat shakled
by joint ventures which have been established with Novozymes and Genencor, limiting the damage they can inflict in the West by arbitrary price cutting.
We have recently completed the latest survey of L. Hepner & Associates Ltd.:
'Industrial Enzymes for Starch, Dairy, Detergents, Baking, Textiles, Foods - Current
Status and Outlook by 2010' with the objectives of:
During the past decade significant changes have occurred in the antibiotics industry,
due to the following factors:
The establishment of fermentation facilities in China and India producing bulk
antibiotics for sale in Western markets has been a direct cause in the decline of
bulk antibiotics notably penicillins, cephalosporins by Western countries.
At present there are around 50 Chinese antibiotics producers, many small but the
largest [North China Pharmaceutical] have similar capacity as their Western counterparts.
Major Western producers have successfully increased yields of penicillin G and V,
cephalosporin C and erythromycin. Smaller producers who do not invest in R & D are
left behind and find they cannot compete on a price basis with the large research-intensive
companies.
One of the most critical problems affecting antibiotics is the development of novel
antibiotics which effective in treating hospital infections generally due to
methicillin-resistant Staphylococcus Aureus [MRSA]. In former years vancomycin proved
an effective antibiotic to combat such infections but the occurrence of vancomycin-resistance
has underlined the importance of research in this area. One new antibiotic product
linezolid [Pfizer] has already appeared
and is proving useful. Other novel products are in the pipeline.
The antibiotics industry for bulk and speciality products has a bright future provided
Western companies establish peaceful coexistence with Chinese companies and the latter
attempt to price products in normally-accepted means. The introduction of a new generation
of antibiotics effective against MRSA life-threatening diseases is provides an important
challenge to microbiologists and biotechnologists. There is little doubt that the next
years will witness the launch of new products for these applications. For further
information see our survey: 'The Antibiotics Industry - Current Status and Outlook
by 2010'
