Abstract
An engineering method was developed to allow genetic modification and isolation of lactic acid bacteria cells that lack lactate dehydrogenase and acetolactate decarboxylase activities. In cells with these modifications and an isobutanol biosynthetic pathway, improved production of isobutanol was observed.
