Abstract
alpha -Amylase production by Bacillus subtilis and Bacillus amyloliquefacie ns was investigated in polyethyleneglycol (PEG)-containing growth medium. F ive different molecular weight PEGs (600, 3000, 4000, 8000 and 20,000) were used. Enzyme production with B. subtilis increased 21% in medium containin g 5% PEG 3000, but enzyme production with B. amyloliquefaciens increased 31 % in medium containing 5% PEG 600 and 21% in medium containing 2% PEG 8000.
