The growing awareness of environmental problems provided the stimulus for biotechnology to address many aspects of the relationship between biotechnology and the environment. The chapters are mainly devoted to the contribution of biotechnology in solving environmental problems, including biological waste water treatment, utilization of municipal sewage sludge, detoxification of polluted soil and complex utilization of lignocellulosic wastes. There is an examination of possible dangers in such cases as the release of r-DNA organisms into the environment. The relationship of biotechnology and energy (e.g. biogas, landfill gas fuel, photosynthesis systems for fuel production) is also discussed. Biotechnology is the umbrella term that covers various techniques to restore ecological balance. It stands on the understanding of molecular basis of cell functions and our ability to alter cell functions to produce products required by the society. It also helps to degrade the wastes. The book is well written in concise, illustrative and innovative style making it easy for an average reader to be able to understand and enjoy it.
