A shikimic acid nutrition mutant Bs 09 strain was obtained through mutating the Bacillus subtilis by ultraviolet light, it can be used to produce D ribose. The Bs 09 strain was found to grow well in the medium, using glucose or glocitol as carbon source, yeast powder or corn steep liquer as organic nitrogen source and (NH 4) 2SO 4 as inorganic source, with the ratio of carbon and nitrogen being 6. Cultivated for 72 h under the condition of 36℃, pH 6.8 and 230 r/min, the biomass and D ribose conte...
