【摘要】 鞘氨醇单胞菌属是一类丰富的新型微生物资源,可用于芳香化合物的生物降解.该属菌株凭借自身的高代谢能力与多功能的生理特性,在环境保护及工业生产方面具有巨大的应用潜力.但是由于对鞘氨醇单胞菌的认识较晚,该菌的生态价值及经济价值很少被关注,对其的研究也停留在初级阶段.本文综述了鞘氨醇单胞菌属自发现以来的研究进展,包括生理生化特性的描述、分类学研究、生物高聚物的合成、特殊组分鞘脂以及相关酶与基因的研究,并结合目前国际研究的热点,提出值得进一步探讨和研究的问题.更多还原

【Abstract】 Widely distributed Sphingomonas sp., a novel and abundant microbial resource for biodegradation of aromatic compounds, has potential use in environment protection and industrial production for it possesses high catabolic capabilities and diverse substrates for macromolecular refractory compounds, such as PAHs and hexachlorobenzene isomers. As a result of little awareness of Sphingomonas sp., its ecological and economical values are not well understood, and related research still remains at initial stage. This paper reviews the research of Sphingomonas sp. since it has been discovered, including the studies on its physiological and biochemical characteristics, taxonomy, synthesis of biopolymers, peculiar sphingolipids, genes and enzymes. In addition, some problems and methods for further research of Sphingomonas sp. are discussed.更多还原
