title: Degradation/solubilization of Chinese lignite by Penicillium sp. P6.
abstract: Penicillium sp. P6, isolated from coal mine soil at the Qiantong colliery Liaoning Province, Northwest China, can degrade Chinese lignite in 36 h on a plate colony and in 48 h using a 4-day cultured cell-free filtrate. Results of elemental analysis and IR spectrometry indicated that solubilized products exhibited some alterations in comparison to the original lignite. The amount of fulvic acid extracted from the biodegraded lignite was high, and the molecular distribution of the humic acids from biodegraded lignite changed distinctively in comparison to which extracted from the control lignite, possibly due to the depolymerization associated with fungal biodegradation.
