中文摘要：

不同环境中蕴藏的不同微生物对煤有溶解作用,为了探究哪些来源的微生物对煤有更好的溶解能力,本试验从土壤、煤泥、堆肥、腐木和矿井水中分别分离得到细菌、真菌和放线菌,利用这些菌株进行溶煤试验并计算溶煤率,然后比较不同来源微生物的溶煤效果。试验结果表明,土壤中菌的种类最全,其中细菌含量丰富,溶煤效果较好;堆肥和腐木中真菌和放线菌比较丰富,溶煤效果较好;井工生产的煤、煤泥以及矿井水等不适合用于筛选溶煤微生物。

英文摘要：

Coal can be solubilized by different microorganisms from various sources.In order to investigate what kind of microorganisms possesses better solubilizing capability,the different strains such as bacteria,fungi and actinomyces,obtained from soil,coal slime,composts,rotten wood and mine water,were used for coal solubilization.The rates of coal solubilization were calculated and the capabilities of coal solubilization for different microorganisms were compared.The results showed that soil contains different strains,in which bacteria showed good coal solubilization.While fungi and actinomyces are rich in compost and rotten wood,possessing good coal solubilization capability.However,underground coal,coal slime,mine water and so on are not suitable for isolation of microorganisms via coal solubilization.
