oa Molecular Composition of Miocene Lignites and its Decomposition Products in Long-Term Anaerobic Biodegradation Experiments

In this work we showed the changes of molecular composition of Miocene lignites from Poland including detritic coals and xylites incubated with natural microflora and with sewage sludge from the long-term (over 3-year) anaerobic incubation experiment. The compounds present in separated OM fractions (aliphatic, aromatic and polar) were identified by GC-MS methods to determine concentration of substrates and products from lignite’s OM. The labile and non-labile compounds were identified as products of anaerobic biodegradation of lignite.
