Biotransformation of coal by ligninolytic Streptomyces


Coal solubilization by S. viridosporus was oxidative, as shown by Fourier transform infrared spectroscopy and elemental analysis. Compared to the starting coals, the soluble products were enriched in oxygen, nitrogen, sulfur, and ash, but were lower in hydrogen relative to carbon.
