Provides a positive perspective on the increasing problem of environmental pollution. Biotechnology is used in the treatment of environmental pollutants released by industry and has the potential to provide "green" technologies which will tackle the problem of environmental pollution at source by minimizing pollution by manufacturers. This text examines relevant environmental legislation, the ecology of pollution and the science and technology behind biotreatment strategies for each of the major classes of environmental pollutants. A balanced and objective course text for students of environmental microbiology and environmental pollution. Concentrates on areas where practical biotreatment technologies exist, drawing on real-life case studies from industry. Gives an appreciation of both biotechnology and ecology which is needed to tackle problems of environmental pollution effectively. Covers an area of growing importance; an increasing number of courses deal with this subject.
