Abstract
The growth of yeast strains Saccharomyces cerevisiae, Rhodotorula rubr a and Bullera alba isolated from natural lake microflora was examined in the presence of prehydrolysis lignin and/or its water-soluble deriv ative. The stimulation effect of the water-soluble lignin derivative w as higher in comparison with that of unmodified lignin. The structural changes of the lignin macromolecule by the yeasts determined by IR sp ectroscopy indicate oxidative degradation and demeth(ox)ylation simila r to that found with lignin-degrading hyphal fungi. The results indica te a partial utilization of lignin by the yeasts as carbon source.
