Haloalkaliphilic Protease Production by a Newly Isolated Moderately Halophilic Bacterium Pontibacillus sp.SY-8

Microbial proteases are important class of enzymes, which constitute more than 65% of the total industrial enzyme market. A challenge faced by industrial application of microbial proteases is optimal activity and stability in a wide range of salinity. Halophilic proteases, which are active both at low and high concentrations of NaCl, are needed. 

Given their potential use, there has been renewed interest in the discovery of proteases with novel properties. Halophiles are microorganisms which grow over an extended range of salt concentrations (3–30% NaCl, w/v), include the halophilic bacteria and archaea. They are found in salt marshes, marine ecosystems, salted meats, hypersaline seas, salt evaporation pools and salt mines. Read More>>>>>>
