| Abstract: | Strain LXA10 was isolated from Kobresia capillifolia,a kind of advantageous plants in alpine grassland in the Eastern Qilian Mountains.The PKO culture results indicated that capacity of phosphate-solubilizing of endophytic bacteria LXA10 was 28.14 mg·L-1,and the capacity was obviously different in different culture media.Fe2+、 Mn2+ 、Mg2 could promoted the LXA10 strain phosphate solubilization ability.It was also found that the capacity was not directly related to pH of media.The strain was identified as Bacillus subtilis,based on its 16S rDNA sequence,physiological and biochemical characteristics. |
