title: Growth of Saccharomyces cerevisiae, Rhodotorula rubra and Bullera alba in the presence of beechwood prehydrolyzate-based lignin fractions.
abstract: The growth of yeast strains Saccharomyces cerevisiae, Rhodotorula rubra and Bullera alba isolated from natural lake microflora was examined in the presence of prehydrolysis lignin and/or its water-soluble derivative. The stimulation effect of the water-soluble lignin derivative was higher in comparison with that of unmodified lignin. The structural changes of the lignin macromolecule by the yeasts determined by IR spectroscopy indicate oxidative degradation and demeth(ox)ylation similar to that found with lignin-degrading hyphal fungi. The results indicate a partial utilization of lignin by the yeasts as carbon source.
