PROCEDURE FOR THE PRODUCTION OF L-LISINE OR L-TREONIN USING THE BACHTERIA ESCHERICHIA THAT PRESENTS ACTIVITY OF THE MALIC ENZYME ATTENED.

摘要

Process for producing L-lysine or L-threonine, which comprises the cultivation of a bacterium in a medium to produce and secrete said L-lysine or L-threonine, and collect the L-lysine or L-threonine from the medium, in which said bacterium is an Escherichia bacterium that has the capacity to produce L-lysine or L-threonine, and in which said bacterium is modified so that a malic enzyme is eliminated or the activity of a malic enzyme is reduced compared to a non-strain modified, in which the gene encoding said malic acid enzyme comprises sfcA and / or b2463.
