¡¡¡¡The
technology is a new high additional value product developed starch
deep processing with biotechnology. With the study on the biological
pharmaceuticals for anti-tumor, anti-virus and nucleic acid medicine
development, D-ribose as their raw material component is more
and more needed on the market. A stable and high yield mutant-Bacillus
subtilis mutant for D-ribose production was selected. The purity
of D-ribose reached to over 99%, which was produced by deep aerobic
fermentation and taking glucose as its material with quick fermentation
and high sugar productive rate and transforming rate. The technology
reached to the world level.
Naturally D-ribose doesn't exist as a monomer, it is a series
of high expensive biochemical reagent. As it has been produced
by cheap microbiological fermentation, the pharmaceutics material
riboflavin and ribazole were solved. Especially as its unique
function of virus and tumors resistance and an original material
for nucleic acid medicines were paid much attention on the market.
At present, he price of D-ribose is 32 USD/pound, the annual requirements
at home and abroad are about 5000 tons and increase of 11% per
year. The cost of fermented D-ribose estimates 50-80yuan /kg for
crystal product and the selling price is 300 yuan/kg. If annual
output is 200 tons, the value is 60 million yuan, the profits
40 million yuan. The economic benefit is remarkable and has bright
future.
