The lignolytic capacity of some natural bacterial isolates was examined. Strains were selected from samples of decaying wood by growth in a minimal medium containing aromatic compounds with a structural relationship to lignin as the sole carbon sources. These included derivatives of benzoic and phenylpropanoic acids, as well as a mixture of low molecular weight compounds obtained by fractionation of kraft lignin. Reversed-phase high-performance liquid chromatography analyses before and after cell growth in the latter revealed a degradation pattern of the different compounds present in the culture which was characteristic for each of the strains studied.
