摘　　要：嗜麦芽窄食单胞菌广泛分布于大自然各种环境中,它的氧化代谢系统能够有效降解烷烃及多环芳香烃污染物并将其降解,同时该菌还具有吸附重金属的能力。嗜麦芽窄食单胞菌是典型的植物促生菌,能够分泌多种酶类、抗菌素和生长素等代谢产物,促进植物生长,防控真菌病害,抑制线虫生长。嗜麦芽窄食单胞菌的这些特性在环境污染治理、农林生产方面都有较大应用价值。通过综述嗜麦芽窄食单胞菌生物除污和植物促生的作用及机理,为嗜麦芽窄食单胞菌的进一步研究和应用提供参考依据。Stenotrophomonas maltophilia is a gram-negative bacterium, and widely distributed in nature. It has multiple dioxygenase that can biodegrade alkane and polycyclic aromatic hydrocarbons （PAHs）, and also adsorb heavy metals. S. maltophilia is a kind of typical plant growth-promoting rhizobacteria. It can secrete various hydrolytic enzymes and secondary metabolites that enhance-plant growth, prevent and control fungal diseases along with nematode. Owing to the above features, S. maltophilia possesses the significant application values in environmental remediation, agriculture and forestry. The mechanisms of bioremediation and plant growth-promoting of S. maltophilia are summarized, which is expected to provide a reference for further studies and application of S. maltophilia.
