Abstract
Biotransformation of powdered hard coal and its organic extract was achieved by means of Piptoporus betulinus, Nocardia rubra and Pseudomonas aureofaciens in aqueous medium. The process of depolymerization was evaluated on the basis of Chromatographic and spectral data. Gas chromatograms, high-performance size exclusion chromatograms and u.v., i.r. and 1H n.m.r. spectra are discussed.
