¡¡¡¡D-ribose production by fermentation £¼BACK£¾

¡¡¡¡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.
