Today the need for enzymes in the bioprocesses and industrial fields has grown to a peak level for their role as natural catalysts. Various multiple forms of enzymes are being searched for tremendously satisfactory properties and commercial applications. Enzymes furnish several advantages such as specificity and lower cost, and their ability to be preserved for a long time. Their biodegradability provides an eco-friendly solution to industrial processes. Microorganisms are preferred protease sources over plants, animals, and other eukaryotic organisms. Among microorganisms, bacteria are the most potent producer of alkaline proteases. Proteases are responsible for more than 60 % of total global enzyme sales. They can be described as a hydrolytic biocatalyst; whose role is to catalyze the breakdown of protein polymers. The author of this book has attempted to present and demonstrate the Characterization of ALKALINE PROTEASES from Bacterial Isolates DM-02 & DM-11 and its influence on water quality in remote rural areas. I hope this comprehensive research might help the young, dynamic scholar interested in working in the above field.
