摘要: 本文工作从甘蔗糖厂分离得到了葡聚糖产生菌GXMY-1,经鉴定为肠膜明串珠菌,并研究了其产生葡聚糖摇瓶发酵的适宜条件。结果为:装量50ml/250ml、接种量10%、pH7.0、温度25℃、转速170r/min、发酵周期26h。在该条件下最高转化率为76%。

Abstract: This paper described the isolation and identification of the dextran- producting strain GXMY-1. It was isolated fromthe sugarcane juice, and was identified to be one Species of Leuoconostoc Mesenteroieds . The primary fermentation-conditionsto produce dextran were studied. The results were: inoculating quantity 10%, flask content 50ml/250ml , pH7.0, temperature 25℃, rotation speed 170r/min,and fermentation time 26h. The conversion rate could reach 78% under the conditions.
