Bioremediation of Metals and Inorganic Compounds - 5(4)

Bioremediation has been a problematic alternative for remediation of metals and inorganic compound contamination. Unlike organic contaminates, which often can be broken down by biological processes into relatively harmless metabolites and byproducts, metals are elemental. Further, metals and their salts often have an inhibitory effect on biological activity. However, despite these potential pitfalls, there has been progress recently in applying bioremediation technologies to metals and inorganics. This volume encompasses topics such as lead solubility reduction, chromium reduction, denitrification, volatilization of selenium in soils, metals recovery from acid mine drainage, and even the possibility of applying artificial neural network technology to aid in bioremediation. This book is part the eight-volume proceedings from the Fifth International In Situ and On-Site Bioremediation Symposium held in San Diego, April 1999.
