摘要：

Several fundamental aspects of microbial coal liquefaction/solubilization were studied. The liquefied/solubilized products from coal by microorganisms were analysed. The liquid products analysed by IR titration and UV/visible spectrometry showed some alterations with regard to the original coal. Humic acids extracted from the liquefied lignite showed a reduction in the average molecular weight and a increase in the condensation index, probably due to depolymerization caused by microorganisms. The mechanisms implicated in coal biosolubilization by two fungal strains, M2 (Trichoderma sp.) and M4 (Penicillium sp.) were also studied. Extracellular peroxidase, esterase and phenoloxidase enzymes appear to be involved in coal solubilization.
