Factors regulating production of <b>α</b> ‐galactosidase from <b> <i>Bacillus</i> </b> sp. JF _<b>2</b>

Abstract

Certain factors affecting the production of cell-associated alpha-galactosidase by Bacillus sp. JF2 were investigated. The intention was to maximize alpha-galactosidase activity of potential commercial application, by consecutive optimization of growth media and conditions. The highest alpha-galactosidase activity was obtained when grown on melibiose, whereas sucrose inhibited the production of alpha-galactosidase, alpha-Galactosidase production was optimally active at pH 7.5 and 55 degrees C. It was identified that a soy effluent stream could be used as the best carbon source for alpha-galactosidase by Bacillus sp. JF2.
