嗜盐微生物在环境修复中的研究进展

The Recent Advances in Halophilic Microorganisms for Environmental Bioremediation

摘要:

人类活动产生的污染物，使一些天然盐环境遭受不同程度的污染，或者使环境受到污染物与高盐的双重污染。在高盐条件下，非嗜盐微生物的代谢会受到抑制，其生物修复效率明显降低，甚至丧失修复能力。嗜盐微生物则能够在高盐环境中栖息繁殖，凸显其修复被污染高盐环境的生物学效率和广阔的应用前景。就嗜盐微生物降解石油烃、芳香烃衍生物和有机磷等污染物的研究进展进行了综述和讨论。

Abstract:

As a result of various anthropogenic activities, natural saline environment polluted by contaminants and the environment polluted by both contaminants and salts frequently occur. In these saline environments, non-halophilic microorganisms have ineffective bioremediation, even lose the function of bioremediation. Halophilic microorganisms are able to thrive in high salt conditions. It is obvious that the halophilic degraders are more useful for the bioremediation of contaminated saline environments and may be potentially used in a wide of application. The objective of this review is to summarize the research progresses of halophiles in the biodegradation of petroleum hydrocarbons, aromatic hydrocarbon ramifications, and organophosphorous.
