摘要:

鞘氨醇单胞菌(Sphingosinomonas)是一类革兰氏阴性菌,对芳香化合物和多环芳烃具有较强的降解能力。不少研究表明,鞘氨醇单胞菌对重金属具有降解能力,相关功能基因的表达过程也有发现,但其降解机理和完整降解过程尚未探明。文章归纳了鞘氨醇单胞菌的研究现状,总结了鞘氨醇单胞菌对重金属污染的修复效果,分析了其修复过程中的影响因素及其促进植物生长的作用机制,探讨了鞘氨醇单胞菌在重金属污染土壤修复中的关键基因和作用机理,可为进一步开发利用鞘氨醇单胞菌修复环境污染提供思路和依据。

关键词: 鞘氨醇单胞菌(Sphingosinomonas), 土壤重金属, 生物降解, 促植物生长菌

Abstract:

Sphingosinomonas is gram-negative bacterium, which could degradate aromatic compounds and polycyclic aromatic hydrocarbons. Works indicated that Sphingosinomonas could degradate heavy metals, and the expression process of related functional genes had been discovered. However, the degradation mechanism and the complete degradation process has not been well elucidated. In this paper, the research status of Sphingosinomonas was summarized, the remediation effects of Sphingosinomonas on heavy metal pollution was reviewed, the influencing factors in the remediation process was evaluated as well as its mechanism of promoting plant growth. In addition, the key genes and mechanisms of Sphingosinomonas in the remediation of heavy-metal contaminated soil were analyzed, which offered ideas and basis for the further development and utilization of Sphingomonas in the remediation of environmental pollution.

Key words: Sphingosinomonas, heavy metals in soil, biodegradation, plant growth promoting bacterium
