調整された酸素飽和条件下における、発酵によるＬ−シスチンの製造方法

摘要

Producing L-cystine, comprises fermenting a microorganism strain in a fermentation medium, in which L-cystine is present in an amount of at least 70%, based on the total cysteine precipitated. The oxygen saturation of the fermentation medium during the L-cystine formation is maintained at 1-40+- 3%.
