Enzyme activity and microbial content of acid fish silage

The activity of acidic cathepsins and lipases were followed during the storage of five sliage samples which were prepared from different raw materials. The hygienic quality of fish silage and the dominant microorganisms were determined. Activity of acidic cathepsins and lipases varied with the differences in the raw materials, Fish silages were free from coagulase positive Staphylococcus aureus, Salmonella sp. and Vibrio parahaemolyticus. The count of yeasts increased with the progress of storage time and Candida rugosa as well as Candida lipolytica were predominated. Penicillium was the predominant genus of mold
