Phosphorus Solubilization of Bacillus amyloliquefaciens YP6 for Three Shell Powders

Abstract:

The study investigated the plant growth promoting character and the phosphorus- solubilization in shell powder and soil of the strain Bacillus amyloliquefaciens YP6 (YP6) isolated from the rhizosphere of a plant in phosphorite mining area in Guizhou. The results showed the strain YP6 had good growth-promoting ability. Furthermore, after 7 days' fermentation by strain YP6, the soluble phosphorus contents in shell powders (oyster, clam and fresh oyster) and the mixtures of soil and shell powders were 44.9, 39.2, 40.3, 86.4, 73.1, 74.8 mg/L, respectively. This study showed that the strain YP6 had remarkable phosphorus solubilization in both soil and shell powder.
