Bacterial strain of Escherichia coli BKIIM B-3996 as the producer of L-threonine

A bacterial strain of Escherichia coli is described which produces L-threonine, and is obtained by a process comprising transduction by bacteriophage P1 which bears a transposon which inactivates threonine dehydrogenase activity, and isolation of a transductant lacking threonine dehydrogenase activi...
