Effect of salinity on community structure and naphthalene dioxygenase gene diversity
Background A variety of saline and hypersaline environments are present on earth. Hypersaline environments are those containing higher salt concentrations than seawater. Saline and hypersaline environments are frequently contaminated with polycyclic aromatic hydrocarbons (PAHs) as a result of industrial activities. Because of their toxic and carcinogenic potential, PAHs are of particular concern(Santodonato, 1997). High salinity and wide saline fluctuation make organic compound pollution difficult to treat by conventional bioremediation methods (Diaz, et al, 2002). One of the current challenges in bioremediation of PAHs in saline environment is the better understanding of the responses of microbial community to saline fluctuation. The aim of this study is to analyze the effect of salinity on PAH-biodegrading, community structure and ndo gene diversity of a moderately halophilic bacteria consortium, thus analyze the relationship between them to explore the PAHbiodegrading mechanism. To our knowledge, this is the first description of effect of salinity on ndo gene diversity in a moderately halophilic microbial consortium.
