Isolation and Characterization of Thermostable Protease Producing Bacteria from Soap Industry Effluent.

Abstract

This study is a search for potential thermostable protease producing strain. Among nine protease producing strains screened from soap industry effluent, one was selected as promising thermostable protease producer and identified as Bacillus subtilis. The activity of the protease produced by this organism is stable up to 70oC. The optimum yield was achieved after 48 hours of culture, at 65oC with the pH 8.0. The maximum protease activity was observed at 65oC and at pH 8.0.
