malic enzyme activity of L- lysine or L- threonine using the attenuated bacterium Escherichia way

摘要

present in the L- lysine or L- threonine production of malic enzyme has the ability of the cells within the normal not acting bacteria belonging to the genus Escherichia transformed , and the art by culturing the bacteria in a culture medium to produce and accumulate them L- lysine or L- threonine , L- lysine , including a collection box or L- threonine from the medium , the process for the production of L- lysine or L- threonine is described .
