    摘要: A mutant strain having an ability to produce L-glutamic acid in the absence of any biotin action-suppressing agent in a medium containing an excessive amount of biotin is obtained by giving temperature sensitivity with respect to a biotin action-suppressing agent to a coryneform L-glutamic acid-producing bacterium. This strain is cultivated in a liquid medium to produce and accumulate L-glutamic acid in the medium. A mutant strain having an ability to produce L-lysine and L-glutamic acid in the absence of any biotin action-suppressing agent in a medium containing an excessive amount of biotin is obtained by giving temperature sensitivity with respect to a biotin action-suppressing agent and giving L-lysine productivity to a coryneform L-glutamic acid-producing bacterium. This strain is cultivated in a liquid medium to simultaneously produce and accumulate L-lysine and L-glutamic acid in the medium.
