Abstract
|
|
|
|
The conditions for /-galactosidase production from alkalophilic, thermophilic Bacillus sp. TA-11 were investigated. The maximal enzyme production was obtained when the strain was cultured at 501C for 5 days with fed-batch culture in the optimal medium containing 1.5% lactose, 0.6% yeast extract, 0.15% K2HP04 and initial pH 9.5, and then final enzyme activity under the above conditions was 5200 unit/ml of cell free extract.
