    摘要: A novel technique for improving L-cysteine-producing ability of bacteria is developed to provide a method for producing L-cysteine, a related substance thereof, or a mixture thereof. L-cysteine, a related substance thereof, or a mixture thereof is produced by culturing a bacterium belonging to the family Enterobacteriaceae, which has L-cysteine-producing ability and is modified so that expression of gene(s) selected from the group consisting of the ygaZH genes and the ychE gene is increased compared with a non-modified strain, in a medium, and collecting L-cysteine, a related substance thereof, or a mixture thereof from the medium.
