Abstract A considerable part of soil phosphorus is bound to metal cations or metal oxides, and cannot be used in these forms by soil microbes and plants. Phosphate-solubilizing bacteria (PSB) are abundant in pectin-rich rhizosphere, and their pectin-degrading activity has been reported. Therefore, we hypothesized that pectin activates PSB and promotes soil phosphorus solubilization. To test this hypothesis, we first tested the phosphate-solubilizing activity of pectin-degrading bacteria. PSB were more frequently isolated from pectin-containing medium, compared with other media (P

果胶驱动土壤中微生物磷的溶解：来自基于隔离和社区规模方法的证据

摘要 相当一部分土壤磷与金属阳离子或金属氧化物结合，不能以这些形式被土壤微生物和植物利用。磷酸盐溶解细菌（PSB）在富含果胶的根际中含量丰富，并且已经报道了它们的果胶降解活性。因此，我们假设果胶激活 PSB 并促进土壤磷溶解。为了验证这一假设，我们首先测试了果胶降解细菌的磷酸盐溶解活性。与其他培养基相比，PSB 更常从含果胶的培养基中分离出来（P
