摘要
对5L发酵罐上培养冰核活性细菌XanthomonasampelinaTS206的发酵工艺条件进行了系统的研究,确定了最适的工艺条件为:通气量2L/(L·min),搅拌速度500r/min,接种量10%,最适培养时间48h,所获得的Xan-thomonasampelinaTS206菌体干重为12·934g/L,冻滴率为100%。
The ice nucleation-active bacteria was cultured by using a 5L fermentor and the conditions for culture of the bacteria were obtained. The optimal conditions for the ice nucleation-active bacteria were studied and the results were: ventilation amount 2L/(L·min), fermentor agitation 500 r/min, and the seeded volume 10%. Under the optimized conditions, the ice nucleation-active bacteria could reach 12.394 g/L with the ice nucleation activity of 100%.
