Curie-point pyrolysis mass spectra of twelve low-rank US coals with various degrees of natural weathering were correlated with the results of biosolubility screening tests involving six selected microorganisms as well as with a specially designed alkaline solubility test. The main objectives of this study were to determine which mass spectral characteristics, if any correlated with the degree of biosolubilization trends, a main trend which correlates positively with the presence of severely oxidized aromatic moities in the coal and apparently enables biosolubilization by all six microorganisms, and a second trend which correlates with relatively high concentrations of acid components and enables biosolubilization by only two or three of the organisms. The chemical and biological significance of these trends is not yet completely understood. Finally, in agreement with previous reports a strong positive correlation was observed between biosolubility and alkaline solubility.
