Abstract
Aureobasidium pullulans grew well in media containing glucose, fructos e, xylan or xylose but beta-xylanase was only produced with xylan or x ylose. Lactose and maltose were poor substrates for growth. Beta-Xylan ase production was repressed in media containing glucose or fructose a long with xylose. Agricultural residues, such as wheat bran, paddy hus k and rice straw, could be used as carbon sources for growth and beta- xylanase production of Aureobasidium pullulans. Tween 80 at 0.5% (v/v) increased the yield of beta-xylanase by up to 20%.
