Biotechnology is a multidisciplinary field which has been considered in several National Development Programmes as one of the strategic areas, involving edge technologies and promoting new bio-industries as source of a considerable amount of new products with high impact in agriculture, the food and chemical industry and also in the health sector. Among the various subfields with biotechnology, the one dealing with environmental issues is currently one of the major demand and development. Environmental biotechnologies are increasingly being viewed as a major weapon against environmental damage. The present title "Environmental Biotechnology" deals with such information at various levels, from introductory to advanced. This volume is aimed at providing information at various levels, from introductory to advanced aspects, including general concepts of environmental policy, applications and specific case studies related to both environmental biotechnology and cleaner bioprocesses. It is also aimed at benefiting readers of different backgrounds, including engineers, consultants, scientists and decision makers working for industry, government, academia and social or private organizations.
