摘要：

Eight different strains of Bacillus were isolated from fermented fish (Budu) and their proteolytic enzyme activities were determined after 18 h cultivation at room temperature (35-degrees-C). Four isolates possessed high protease activities. Optimum pH for these enzymes was between 7.0 and 8.0 and the optimal temperature was 55-degrees-C. The proteases retained 40% of their original activity after 20 min at 55-degrees-C but lost all activity at 65-degrees-C. Three of the four isolates were identified as Bacillus subtilis, the fourth as Bacillus licheniformis.
