  • Characterization of Lignite Biosolubilization Products by Indigenous Moulds from Soil of Coal Mining in South Sumatera. Biosolubilization of coal is a potential technology of converting solid coal to liquid fuel and chemicals at ambient condition. Our previous research has successfully isolated four moulds from soil at coal mining - South Sumatera and has potency as lignite biosolubilization agent, i.e. T1, T2, T4, T5. The objective of this research was to characterize of lignite biosolubilization products by four isolates. The method used was sub-merged culture. Cultivation medium was MSS+ (minimal salt + sucrose 0,1% + yeast extract 0,01% + lignite 5 %). Incubation was conducted at room temperature for 28 days. The result showed that all indigenos moulds have different ability in lignite biosolubilization. The highest biosolubilization occurred after 7 days of incubation belonging to T1 isolate. However, GC-MS analysis showed the largest percentage of hydrocarbon compound which equivalent to gasoline and diesel was T5 after 7 days of incubation.
