Metabolome of aluminum-tolerant phosphate-solubilizing fungi

We constructed a bacterial fungal synthetic community and found that it has stronger phosphorus solubilization ability than a single bacterium or fungus. Among them, fungi mainly play a role in phosphorus solubilization, while bacteria can promote fungal phosphorus solubilization. Through metabolomics, the mechanism of fungal phosphorus solubilization is analyzed to further explore whether fungi utilize bacterial metabolites to promote phosphorus solubilization. It was found that fungi mainly utilize organic acids to dissolve phosphorus, while bacterial metabolite whey acid can be utilized by fungi to promote their ability to dissolve phosphorus.
