Cgm. De Souza et al., Influence of growth conditions on the production of xylanolytic enzymes byAspergillus flavus, J BASIC MIC, 39(3), 1999, pp. 155-160
Investigations were carried out to optimize the culture conditions for the
production of xylanase and beta-xylosidase by Aspergillus flavus, a filamen
tous fungus isolated from soil. The production of enzymes was tolerant to a
wide range of initial culture pH values. Maximum xylanase (190 U/ml) and b
eta-xylosidase (35 U/ml) production was obtained when the strain was grown
on mineral medium supplemented with 3% (w/v) corn cob powder as the carbon
source. The enzymes had optimal activities at pH values between 5.5 and 6.0
and exhibited high activity and stability under alkaline conditions.
