单级连续发酵生产D-核糖

Study on Production of D-Ribose Single-stage Continuous Fermentation

考察了D-核糖单级连续发酵的起始时间、稀释率、流加糖浓度对D-核糖单级连续发酵的影响。结果表明,在24 h后以稀释率为0.06 h-1,流加糖浓度为200 g/L时进行单级连续发酵,D-核糖产率达到最大,可达4.0 g/(L.h)以上。

Starting time of D-ribose single-stage continuous fermentation was detected.The effects of dilution rates and influent glucose concentration on single-stage continuous fermentation were also investigated.The results indicated that optimal productivity reached more than 4.0 g/L/h under the conditions of starting time 24h,dilution rates 0.06 h-1 and influent glucose concentration 200 g/L.The steady stage was obtained effects 48h of continuous fermentation,and various parameters held stable for 160 h.
