Abstract

Bacillus licheniformis M27 produced 21 000 units of alpha-amylase/g dry bacterial bran under solid state fermentation in wheat bran medium enriched with 3.3% di-ammonium hydrogen phosphate. The crude enzyme had a temp. optimum of 90 degree C in 0.5% starch solution and pH opitma of 6.5-7.0 and 9.5 ( greater than 75% activity over the pH range 6.0-10.5).
