微生物法对煤进行改性的研究进展

STUDY ON MICROBIOLOGICAL MODIFICATION OF COAL

介绍了几种对硬煤和褐煤进行微生物改性的方法、测试手段、改性效果和改性效果好的菌种，以及当前比较先进的菌种分离技术．通过微生物法对硬煤和褐煤进行改性，煤的溶解性有了一定的提高，其中有些方法用于降解煤样．可以分离出芳香化合物．用于改性煤样的担子纲类真菌对煤的改性效果较好．

Several microbiological methods are proposed in this paper. The better fun- gies .screening system .testing methods and the modification results are showed. The coal involved including hard coal and low-rank coal. The solubility of modified coal is greatly enhanced. By de- grading coal some aromatics are obtained which will be useful in some other research .And both of coal can be effectively modified by basidiomycetes.
