Abstract
We investigated electron spin resonance (ESR) parameters (free radical concentrations, g values, and linewidths) of a variety of fungal melanins. The influences of oxygen, culturing conditions, methylation, solvent extractipn, aCld hydrolysis, and persulfate oxidation on ESR parameters were also studied. Our major objective was to gain a better knowledge of the similarities of fungal melanins with soil humic aClds. We suggest that these biopolymers are different from soil humic aClds with regard to ESR parameters. © Williams & Wilkins 1985.
