【摘要】：利用枯草芽孢桿菌對貴州的某磷礦石進(jìn)行微生物浸出試驗(yàn)研究。結(jié)果表明,枯草芽孢桿菌對磷礦石有較強(qiáng)的溶解能力。最佳培育條件為:磷礦粉濃度3g/L,培養(yǎng)溫度37℃,初始pH=7,以醋酸鈉為碳源。在最佳條件下,磷的浸出率達(dá)51.76%。
[Abstract]:Microbial leaching of a phosphate rock from Guizhou province was studied by Bacillus subtilis (Bacillus subtilis). The results showed that Bacillus subtilis had strong dissolution ability to phosphate rock. The optimum cultivation conditions were as follows: phosphate rock powder concentration 3 g / L, culture temperature 37 鈩，
