| 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. |
