生物的铝毒害和耐铝毒机制可以为植物耐铝毒机制的研究提供一种新视角。目前的研究表明铝作用于微生物细胞的细胞壁、细胞膜、细胞核和细胞器,影响微生物的物质和能量代谢,抑制微生物的生长和发育;针对这些毒害作用,铝毒耐受微生物通过多途径全方位的机制适应外界的铝毒环境。本文结合我们的研究工作,综述了微生物的铝毒害和耐铝毒机制。

Abstract: In acidic soils, aluminum (Al) toxicity is one of the critical problems, which could limit crop production. Al can cause toxicity in microorganisms as well. Al toxicity tolerant mechanism research of microorganisms can give a new perspective to that of plants. Present researches show that Al acts on microorganisms’ cell wall, cell membrane, cell nucleus and organelle, affects microorganisms’ substance and energy metabolism, and inhibits microorganisms’ growth and development. Responding to these toxicity actions, Al toxicity tolerant microorganisms adapt to the outside Al toxicity environment by multi-pathway and all-direction mechanism. In this paper, combination with our researches, Al toxicity and tolerance mechanism of microorganisms were reviewed.
Key words: microorganisms; aluminum toxicity; tolerance to aluminum toxicity; multi-pathway; all-direction
