Abstract:
Based on the soil of the Gonggan orchards of the Guangxi Zhongshan county,a high-efficiency phosphorous-solubilizing bacteria capable of converting insoluble or indissolvable into soluble phosphorus was selected by molybdenum-antimony colorimetric method.A high strain,through 6 passages,a highly stable solution of inorganic phosphorus and genetically stable strain W3 was obtained.According to strain W3 colony morphological characteristics,18S rDNA homology analysis,NCBI database comparative analysis and other studies,the preliminary identification strain W3 was Aspergillus flavus.The effect of inorganic phosphorus solution of strain W3 was investigated.The results showed that phosphorus bacteria W3 in the inoculation amount of 7%,culture temperature 30 ℃,shaking speed 220 r?min-1.Under the condition of 7 days,the optimal solution of inorganic phosphorus was 148.57 mg?L-1.
