Effect of certain carbon sources of growth medium on ± -amylase production by Aspergillus versicolor and Aspergillus terreus (original) (raw)
Aspergillus versicolor and Aspergillus terreus isolated from deteriorated rice using potato dextrose agar grew at 25 o C and expressed �± -amylase activity in a growth medium with potassium nitrate as nitrogen source and various carbon sources. The carbon sources which were varied were lactose, maltose, starch, sucrose, galactose and glucose. Rice also supported growth and induced �± -amylase production by these isolates. Aspergillus terreus seemed a better inducer. (Adekunle Odunayo Adejuwon, Bukola Ayodeji Bamkefa, Joseph Omololu-Aso, Shadrach O. Agunbiade.
