Method for producing target substance by fermentation

摘要

A method for producing a target substance by utilizing a microorganism by culturing the microorganism in a medium to produce and accumulate the target substance in the medium and collecting the target substance from the culture is described. The microorganism is a mutant recombinant strain in which maltose assimilation is controlled by reducing or eliminating the interaction between IIA^Glc protein of the glucose PTS and a protein involved in non-PTS uptake of maltose.
