对游离和固定化的谷氨酸C. glutamum细胞生产l -赖氨酸进行了分析。在含有80 g/L葡萄糖作为碳源的培养基中培养24小时，未生长的自由细胞和固定化的自由细胞比生长的自由细胞产生更高水平的赖氨酸。为了提高赖氨酸产量，研究了初始生物量和酵母浸膏浓度对赖氨酸产量的影响。
Free and immobilized cells of C. glutamicum were analyzed for production of L-lysine. Non-growing free cells as well as immobilized ones produced higher levels of lysine than growing free cells, when cultured for 24 h in a medium containing 80 g/L glucose as a carbon source. The effect of initial biomass and yeast extract concentrations was investigated in order to improve lysine production.
