Abstract
A method for producing L-lysine by fermentation, comprising modifying a gene for coding an NCBI reference sequence NP_601029.1 and/or NP_599350.1 on a Corynebacterium bacterial chromosome to enable the activity and/or expression quantity of NP_601029.1 and/or NP_599350.1 to be reduced; replacing a promoter of one or more genes on the Corynebacterium bacterial chromosome with a EP5 promoter, and fermenting bacteria obtained by modification to produce L-lysine. Also provided are methods and applications derived from the method, and bacteria and promoter that can used in the methods and the applications.
