英文摘要

One mineral-solubilizing bacterial strain designated KT was isolated from a soil in Henan Province, China. The full-length 16S rRNA gene sequence showed 95.2 to 96.7% similarity to the bacteria of the genus Paenibacillus, indicating that the strain KT belonged to the genus Paenibacillus. The potential of this strain to release potassium from silicate minerals was investigated using a potassium-bearing rock as the sole source of potassium to support its growth. After inoculation for 7 days, the concentrations of water-soluble Al, Ca and Fe released from the potassium-bearing rock in active bacterial culture were higher than those from the control with autoclaved inoculum, but the concentration of water-soluble K in active bacterial culture was similar to that in the control. The concentrations of HNO3-extractable Al, Ca, Fe and K from the bacterial culture were also higher than those in the control. These results showed strain KT was able to release potassium from potassium-bearing rock. These results have important implications for extraction of potassium from rocks to support plant growth.
