Evidence of Cell‐Associated Proteinases from Virgibacillus sp. SK33 Isolated from Fish Sauce Fermentation

Abstract

The cell-associated proteinases could be extracted from Virgibacillus sp. SK 33 using lysozyme. The extracted enzyme could be applied to hydrolyze food proteins at NaCl content as high as 25%. In addition, this study demonstrated that not only extracellular but also cell-associated proteinases are key factors contributing to protein-degrading ability at high salt environment of Virgibacillus sp. SK 33.
