Glucosetransportmutanter til fremstilling af biomateriale

摘要

A method is disclosed for restoring a Glu+ phenotype to a PTS &upbar& /Glu &upbar& bacterial cell which was originally capable of utilizing a phosphotransferase transport system (PTS) for carbohydrate transport. Bacterial cells comprising the Glu+ phenotype have modified endogenous chromosomal regulatory regions which are operably linked to polynucleotides encoding galactose permeases and glucokinases.
