摘要
以我室选育的赖氨酸生产菌Ｓ－２１－２４为出发菌株，经硫酸二乙酯（ＤＥＳ）和紫外线（Ｕ．Ｖ．）的复合处理，选育到一株代谢速率高，发酵周期短的新菌株ＦＴＳ－１。对该菌的发酵条件作了研究，选择了最佳培养条件，该菌在５Ｌ发酵罐中发酵４８小时产酸８０ｇ／Ｌ以上，７２小时产酸可达１１０ｇ／Ｌ。
In this paper the L-Lysine producer of Corynebacterium glutamicum S-21-24 has been improved. After mutagenesis by DES and U.V.,a higher L-Lysine-Producing strain FTS-1 has been obtained. It is faster in metabolic rate and shorter in fermentation period than strain s-21-24. In the meanwhile the fermentation technology has been investigated. Under the optimal conditions, FTS-1 can accmulate 80g/lL and 110g/lL Lys-HCl after 48hr and 72 hr respectively in 5L fermentor.
