摘要:
A method for producing L-cysteine and the like is provided by developing a novel technique for improving bacterial L-cysteine-producing ability. The method includes the steps of culturing a bacterium belonging to the genus Escherichia which has L-cysteine-producing ability, and in which expression of a gene involved in sulfite reduction is enhanced, in a medium containing thiosulfate, and collecting L-cysteine, a related substance thereof, or a mixture thereof which accumulate in the medium.
