Abstract

Processing waste, especially visceral wastes from different freshwater and a marine shellfish were evaluated for the proteolytic bacterial load. Proteolytic bacteria associated with the visceral wastes of catla (Catla catla), tilapia (Oreochromis mossambicus), common carp (Cyprinus carpio) and tiger shrimp (Penaeus indicus) were characterized and identified. The major proteolytic microbes associated with the visceral waste included Alcaligenes, Acinetobacter, Aeromonas, Bacillus, Corynebacterium, Flavobacterium, Lactococcus, Lactobacillus, Pseudomonas and Sarcina. The optimum pH, temperature and time of incubation for Bacillus sp MF01 were 9.0, 37°C and 96 h, respectively. The activity profile of the protease extracted from this bacterial culture indicated that the protease was optimally active around pH 8.0 with a specific activity of 10.9 units/mg protein in the crude extract, Protease.
