Abstract
The ability of selected bacterial strains and consortia to mineralize degradation intermediates produced by Phanerochaete chrysosporium from 14C-labeled synthetic lignins was studied. Three different molecular weight fractions of the intermediates were subjected to the action of the bacteria, which had been grown on a lignin-related dimeric compound. Two consortia isolated from wood being decayed naturally by a Ganoderma species of white rot fungus (the palo podrido system) mineralized 10 to 11% of the fraction with a molecular weight of approximately 500 but less than 4% of the higher- and lower-molecular-weight fractions. The consortia mineralized 5 to 9% of the original lignins. The ability of two pseudomonads isolated earlier from lignin-rich environments to mineralize the original lignins or fungus degradation products was much lower.
