摘要
将干酪乳杆菌(Lactobacillus Ceasei)细胞固定有琼脂——聚丙烯酰胺凝胶内,用于生产乳酸。研究了底物浓度,酵母膏浓度,培养温度等因素对固定化细胞生产乳酸的影响。对置换发酵过程中固定化细胞的活性及操作稳定性也进行了研究。
The Cells of Lactobacillus Casei were immobilized in agar gels coated with polyacrylamide for the production of Lactic acid. The effect of substrate concentration, yeast extract concentration and cultural temperature etc. on the lactieacid production was studied. The activity and operational stability of immobilized cell gels were investigated in repeated batch fermentation.
