Hd. Mansilla et al., BIODEGRADATION OF ACIDOLYSIS LIGNINS FROM CHILEAN HARDWOODS BY THE ASCOMYCETE CHRYSONILIA-SITOPHILA, World journal of microbiology & biotechnology, 13(5), 1997, pp. 545-548
The biodegradability of five lignins extracted from Chilean hardwoods
in Chrysonilia sitophila cultures was evaluated. All lignins showed an
increase in their molecular weight after 12 days of culture. Infrared
analysis of the degraded lignins indicated the formation of new subst
ructures containing carbonyl, as well as C-O cleavage reactions. A ran
dom behaviour was observed between the methoxyl/phenolic hydroxyl rati
o of lignins and the extent of biodegradation.
