Abstract: 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
