M. Karni et al., BETA-XYLANASE PRODUCTION BY AUREOBASIDIUM-PULLULANS GROWN ON SUGARS AND AGRICULTURAL RESIDUES, World journal of microbiology & biotechnology, 9(4), 1993, pp. 476-478
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%.
