Book Description

This new volume offers comprehensive coverage of bacterial biosurfactants, the competitive new area of research that has exciting potential application in agriculture and petroleum exploration. The book helps readers to understand the synthesis of biosurfactants by some specific bacteria, their culture, and extraction toward use in bioremediation and enhanced crude oil recovery.

The volume covers the gamut of topics in bacterial biosurfactants in nanostructure, including their comparison to synthetic surfactants, their interaction with microorganisms, and their biochemistry, characterization, genetics of production, bioremedial effects, and more. The volume also explores the myriad uses of bacterial biosurfactants, including in laundry detergents, cosmetics, food production, petroleum, agriculture, medicine and therapeutics, environment, metallurgy, etc.

Attention to biosurfactants has been gradually increasing in recent years due to the possibility of their production through fermentation technology and their potential applications in environmental protection. Despite their numerous advantages over synthetic chemical surfactants, biosurfactants have been unable to compete with chemically synthesized surfactants due to high production costs in relation to the inefficient bioprocessing techniques, poor strain productivity, and use of costly substrates. This volume helps to identify the factors that need to be addressed to reduce the cost of production of biosurfactants.

He also headed the Centre for Petroleum Biotechnology, sponsored by the Oil and Natural Gas Corporation; a government-sponsored MSc biotechnology program, and the Bioinformatics Infrastructure Facility at Tezpur University. He was formerly the Vice Chancellor at Nagaland University (Central), India, and lecturer at Assam Agricultural University, India. He was Senior Scientist and Head of Botany and Biotechnology at the Tocklai Tea Research Institute, Jorhat, Assam, India. He carried out research projects of national importance as the Principal Investigator and supervised many students on research projects, with 15 students earning PhDs to date. He and his research group have so far deposited 11 gene (DNA) sequences in gene banks, and his research group has published over 200 research papers in international journals, seminars, and conference proceedings. A prolific author and researcher himself, Dr. Konwar has published more than 200 articles on popular science, environment, biotechnology, history, national integration, higher education, research needs, etc., and more than 40 scientific articles in national English magazines in addition to books, booklets, and book chapters.
