Production and Characterization of Protease from Serratia marcescens

Extracellular protease produced by Serratia marcescens isolated from the gut of termite (Centrocestus formosanus) was investigated in this study. The effect of temperature, pH, carbon and nitrogen sources on protease production was examined. The extracellular protease was separated from the culture supernatant of the organism through precipitation with ammonium sulfate. The protease was purified by Sephadex G-150 gel filtration and...
