以枯草芽孢杆菌为出发菌株,经紫外线诱变处理,选育出莽草酸营养缺陷型突变株BS－9,其发酵产物经物理、化学鉴定为D－核糖.通过利用碳源、氮源实验,发现该突变株在以葡萄糖为碳源、玉米浆和硫酸铵为氮源的发酵培养基中生长良好,在温度为36℃,PH值为6.8,转速为230R?MIN－1中摇床培养72H,D－核糖质量浓度可高达67.6G?L－1,且葡萄糖基本耗尽“,”A Shikimic acid nutrition mutant BS9 Strain was obtained through mutating the Bacillus subtilis by ultraviolet light; it can be used to produce D ribose. The BS9 strain was found to grow well using glucose as carbon source and corn steep liquer and (NH 4) 2SO 4 as nitrogen source. The process was cultivated for 72 h under the condition of 36 ℃, pH 6.8 and 230 r?min -1 . The content of Dribose was more then 67.6 g?L -1 such that the glucose was almost used up.
