摘 要:
微生物聚谷氨酸（PGA）是一种新型高分子材料，在医药、食品等行业有广泛应用。本文以大豆加工副产物豆粕为培养基发酵生产聚谷氨酸，分别研究了摇瓶发酵培养基的水分含量、碳源、培养温度、时间和接种量等因素对发酵的影响。结果表明，豆粕按1：4的比例加水，加入蔗糖2％，接种量为0.16mL/g，40℃培养24h产量可达4.81％。[著者文摘]

Abstract:
Microbial Polyglutamic acid （PGA）, a new polymer, can be widely applied in medicine and food industries. In this paper, production of PGA by fermentation of soybean meal was studied. The optimal ratio of soybean meal to water, sugar content, culture temperature, time and inoculum in the medium were 1：4, sugar dosage 2%, 40%℃, 24 h and inoculum size 0.16 mL/g, respectively, under which the yield of PGA reached 4.81%.[著者文摘]
