Purification and Characterization of a Novel Extracellular Haloprotease Vpr from Bacillus licheniformis Strain KB111

Abstract

A novel extracellular haloprotease from <i>B. licheniformis</i> was purified, characterized and identified. The purified protease was identified as being a minor extracellular protease (Vpr) and this is the first report on the halotolerance of Vpr. This protease has the ability to work in harsh conditions, with a broad alkaline pH and salinity range. Therefore, it can be useful in various applications in industrial fields.
