In this book, renowned scientists from around the world provide up-to-date and authoritative reviews of the latest scientific research that has contributed to our understanding of the vital importance of microbial biofilms for the biological remediation of contaminated environments. The results of a variety of key case studies are presented to highlight the broad range of treatment approaches and applications at our disposal. In addition, the authors discuss the future trends and likely growth areas in biofilm-related research. This comprehensive volume is indispensable for anyone involved in bioremediation, biofilm research or environmental microbiology. It is also recommended as a reference work for all microbiology libraries.
