近几年来,每年排入海洋的石油及其付产品约611万吨[27]。严重地污染了海洋环境。近代发现海洋中存在着能降解石油烃的微生物,数量庞大,种类繁多,而且有多功能的分解代谢能力,能对油污分解、氧化,并在这基础上生长、繁殖。又加强了降解能力,起到保护海洋环境的作用。比用物理、化学方法处理油污更能获得优良的水质。因 In recent years, about 6.1 million tons of oil and their products are discharged into the oceans each year [27]. Seriously polluted the marine environment. In modern times, there are many microorganisms that can degrade petroleum hydrocarbons in the ocean. They are numerous, diverse and have multifunctional catabolism. They can decompose and oxidize oil and grow and multiply on this basis. But also enhance the ability of degradation, play a role in protecting the marine environment. Than the use of physical and chemical methods to deal with oil pollution better access to water quality. because
