Abstract:
The morphology,cultural characteristics,physiological and biochemical properties of phosphate solubilizing strain BL-11 were studied.Combine with its 16S rDNA sequence analysis result strain BL-11 was identified as Brevibacillus laterosporus.Results showed that the phosphate solubilizing efficiency of strain BL-11was up to 10.91% when with Ca_ 3 (PO_ 3 )_ 2 as the sole phosphorus source in the medium,while the efficiency of that was up to 1.56% when with sands as the sole phosphorus source.An optimal media of BL-11 strain for solubilizing phosphate was obtained by orthogonal test.It was composed of sugar 20g/L,(NH_ 4 )_ 2 HCO_ 3 0.3g/L,MgSO_ 4 .7H_ 2 O 0.5g/L,NaCl 0.3{g/L},KCl 0.5g/L,FeSO_ 4 0.03g/L,MnSO_ 4 .H_ 2 O 0.03{g/L.}_ While other conditions were consisted of initial pH7.0-8.0,180 r/min,and 30℃.
