There are numerous interacting biological, physical and chemical factors that affect survival of both indigenous and introduced bacteria in soil. Three important factors are clay, type, clay content and predation by soil protozoans. These factors are important when considering release of non-engineered and genetically engineered microorganisms (GEMs) into soil. In this review we examine the influence of clays and predatory activity of protozoans on bacterial survival. These aspects are related because protozoa may ingest clay particles as well as bacteria. In addition, clays may protect bacteria from predation by protozoans by increasing the number of protective microhabitats available to bacteria in soil.
