Recent progress in cell-free solubilization of coal
Low rank coal has been solubilized using cell-free filtrates separated from cultures of Polyporus versicolor. Solubilization has been obtained with neat filtrates and with fractions collected from the neat filtrates after gel permeation chromatography. The coal solubilizing enzymes have been collected in enriched fractions with gpc. This increased relative purity has allowed the determination of the average molecular weight of this enzyme by gel permeation chromatography and by polyacrylamide gel electrophoresis. Rates of coal solubilization are dependent on the size of coal particles, mass of coal, temperature, pH, concentration of the cell-free filtrate, and the concentration of several inorganic ions.
