Abstract: Rhizosphere microbial communities play a major role in multiple soil functions. The aim of this study is to assess the relation of bacteria and organic acids in rhizosphere soil and community function induced by soybean genotypes, BX10 [aluminum (Al)-tolerant soybean] and BD2 (Al-sensitive soybean). Organic acid analysis in the rhizosphere soil indicates that BX10 increased the concentration of citric acid, whereas BD2 decreased it; malic acid was only found in the rhizosphere soil of BX10. Redundancy analysis results also showed that the two soybean genotypes induced distinct rhizosphere microbial communities, and citric acid and malic acid had a significantly positive correlation with rhizosphere bacteria of BX10. The community level physiological profiling showed that BX10 might have more influence than BD2 on the ability to metabolize organic C substrates. Sequence analysis indicates that two soybeans stimulate some rhizobacteria, such as species of Acinetobacter, Candidatus Amoebinatus, and uncultured proteobacterium. This study revealed that rhizobacteria of two soybeans may be related to their organic acid exudation.
