The present invention discloses a method for producing a target substance
using a coryneform bacterium comprising culturing a coryneform bacterium
having an ability to produce the target substance in a medium, resulting
in accumulation of the target substance in the medium or cells of the
bacterium, and collecting the target substance from the medium or the
cells of the bacterium. Also disclosed is a coryneform bacterium which is
introduced with a methanol dehydrogenase gene and which has enhanced
activities of hexulose phosphate synthase and phosphohexuloisomerase, and
to which an ability to utilize methanol is imparted or which has enhanced
ability to utilize methanol, and the medium contains methanol as a carbon
source.
