利用青霉菌等４种微生物降解鹤岗风化煤及其稀盐酸处理样，得到了显著降解效果．酸处理风化煤的降解远好于未处理的风化煤．对产物的分析结果表明，微生物的降解作用使煤样结构发生了变化；降解过程中伴随着Ｏ、Ｈ、Ｎ含量的增加，酸性官能团含量及ＦＴ－ＩＲ谱上吸收带的变化．微生物降解煤的能力来自于微生物分泌的酶及伴随而生的培养液中的碱性物质．降解过程中存在来自煤样本身的抑制作用，摇瓶加样量不宜太多．在长达３２ｄ的降解过程中，可被酸沉淀的产物浓度及产率存在一最大值．青霉菌使产物醇羟基减少
The use of four kinds of microorganisms such as Penicillium degradation Hegang weathering coal and dilute hydrochloric acid treated samples, has been significantly degraded. The degradation of acid treated weathered coal is much better than that of untreated weathered coal. The results of the analysis of the products showed that the structure of the coal sample changed with the degradation of microorganisms. The content of O, H and N, the content of acidic functional groups and the absorption band on the FT-IR spectra were accompanied by the degradation process. The ability of microorganisms to degrade coal comes from the enzymes secreted by the microorganisms and the alkaline substances in the accompanying culture fluid. Degradation process exists from the inhibition of the sample itself, shake the bottle sample volume should not be too much. There was a maximum concentration and yield of product that could be acid precipitated during the degradation up to 32 days. Penicillium alcohol hydroxyl product decreased
