AI Technical Summary
Existing technologies struggle to simultaneously achieve efficient nitrogen fixation and activated iron phosphate across a wide acid gradient (pH 3.0-7.0), failing to effectively address the problem of nitrogen and phosphorus deficiency in acidic environments, especially when activity and stability drop sharply below pH 5.5.
A synthetic microbial community of acid-resistant nitrogen-fixing and activated iron phosphate is used, consisting of Pseudomonas donghuensis N-13 and Pantoea agglomerans P-23, with a preferred ratio of 1:1, to form a compound microbial agent for biological nitrogen fixation and activation of insoluble phosphate under acidic conditions.
It significantly enhances available nitrogen content and efficiently activates iron phosphate within a pH range of 3.0-6.0, maintaining high functional activity. It is suitable for the remediation of nitrogen and phosphorus-limited environments in acidic conditions, exhibiting good stability and synergistic effects.
