Mikroorganisme med evne til at danne L-aminosyre og fremgangsmåde til fremstilling af L-aminosyre

摘要

An L-amino acid is produced by culturing a microorganism which belongs to the family Enterobacteriaceae and has an ability to produce an L-amino acid, wherein the bacterium has been modified to enhance orotate phosphoribosyltransferase activity, in a medium to produce and cause accumulation of an L-amino acid in the medium or cells, and collecting the L-amino acid from the medium or the cells.
