Two mutants (Type A and B) induced from Cellulomonas flavigena NTOU 1 demonstrated higher casein-hydrolyzing activity than mother culture. The optimum pH for hydrolyzing casein (pH 8-10) of the mutants and wild type mother culture strain was higher than that for growth (pH 6-7.5). When three strains were employed to hydrolyze whole shrimp, mutant A showed the highest yield (63.5%) of shrimp hydrolysate (SH), followed by mutant B(58.6%) and wild type culture (50.0%). Mutant B produced the best quality of SH and was considered safe, according to animal test, as a starter culture for shrimp sauce processing.
