摘　　要：通过云芝和假丝酵母固体培养港煤试验筛选了易于为它们溶解的煤样;测定了这两种菌在固体和液体培养条件下对扎赉诺尔及平庄硝酸氧化煤的溶煤率,一般可达60—80％;对煤溶物进行了元素分析、红外光谱和核磁共振分析。分析结果初步表明,生物溶解过程中煤的组成和结构发生了一定的变化。The coals solubilized easily by Polyporous versicolor and Cadida ML13 were screened by mean of solid culture. Solubilization of above fungi on nitric-acid oxidized Zalainuoer and Pingzhung lignites was determined at solid and liquid culture condition and they can generally come to 60-80%. The biosolubilized products were analyzed by elemental analysis, infrared spectroscopy and NMR spectra. Results showed that some changes in constructure and composition of biosolubilized products were occurred by bisolubilization process.
