Abstract
Alkalophilic bacterial strains (52) isolated from saline-alkali soils were screened on milk agar medium for their ability to produce alkalin e protease. Fifteen positive isolates were further examined for their extent of alkaline protease production. The most potent producer was i dentified as Bacillus sp. Maximum enzyme activity was achieved in the presence of glucose (1% w/v) and ammonium chloride (1% w/v) at pH 10.5 and 40 degrees C over a 20 h incubation. (C) 1998 Elsevier Science Lt d.
