Enhancement of production of cloned alpha-amylase by lactic acid feeding from recombinant Saccharomyces cerevisiae using a SUC2 promoter
alpha -Amylase production was higher (13 units ml(-1)) when a recombinant Saccharomyces cerevisiae containing a SUC2 promoter was grown with 10 g lactic acid l(-1) than without addition (8 units ml(-1)). With continuous lactic acid feeding in the inducing phase, alpha -amylase increased to 79 units ml(-1) in a 1-l jar fermenter.
