Biotechnology has emerged as an area of activity having tremendous impact on virtually all domains of human welfare and holds a lot of promises and surprises in some of the techniques for the present and future. Spread over fourteen chapters, the book gives an overview of biotechnological means to convert hazardous wastes into useful products, then moves to an important area of biotechnology i.e. proteomics. It touches upon the latest research and developments in diverse areas like bio-informatics, DNA bio-sensors, DNA fingerprinting, mushroom biotechnology, stem cells, bioethics, in vivo induced antigen technology, immobilisation technology, production of 7- aminocephalosporanic acid, therapeutic application of thymic peptides and cyanobacteria as a source of valuable products.
