| Abstract: | A strain, Lactobacillus plantarum RS2-2, with intracellular L-LDH activity was isolated from pickled vegetable juice. After mutating it by nitrosoguanidine combining with ultrasonic, the specific activity was increased from 3.48 U/mg to 7.49 U/mg. The fermentation conditions were also studied in this paper. |
