VERFAHREN ZUR HERSTELLUNG VON L-LYSIN ODER L- THREONIN UNTER VERWENDUNG VON ESCHERICHIA- BAKTERIEN MIT ABGESCHWÄCHTER MALATENZYMAKTIVITÄT

摘要

A bacterium belonging to the genus Escherichia which has an ability to produce L-lysine or L-threonine and which is modified so that a malic enzyme does not function normally in a cell, and a method for producing L-lysine or L-threonine, comprising culturing the bacterium in a medium to produce and cause accumulation of L-lysine or L-threonine, and collecting the L-lysine or L-threonine from the medium.
