“…The devulcanization was achieved by a new class of rubber-degrading microorganisms, belonging to basidiomycetes. Most of the rubber-degrading microorganisms described to date have been characterized by an ability to decompose or grow on NRlatex or NR films, although several strains such as Nocardia, 22 Streptomyces, 23 Fusarium solani, 20 and Penicillium Variable 21 are known to degrade solid rubber vulcanizates. We conclude that, in addition to these microorganisms, wood rotting basidiomycetes are potential microorganisms that degrade solid rubber vulcanizates.…”

A white rot basidiomycete, Ceriporiopsis subvermispora, degraded vulcanized natural rubber (NR) sheets on a wood medium. The fungus decreased the total sulfur content of the rubber by 29% in 200 days, accompanied by the cleavage of sulfide bonds between polyisoprene chains. X-ray photoelectron spectroscopy (XPS) demonstrated that C. subvermispora reduced the frequency of S-C bonds by 69% with a concomitant formation of S-O bonds during the culture period. Dipolar decoupling/magic angle spinning (DD/MAS) solid state 13C NMR revealed that the fungus preferentially decomposed monosulfide bonds linked to a cis- and trans-1,4-isoprene backbone but the cleavage of polysulfide bonds was also observed. In contrast, no decrease in weight or devulcanization of rubber was observed in cultures of a white rot fungus, Dichomitus squalens. The oxidative cleavage of sulfide bonds by C. subvermispora demonstrates that ligninolytic basidiomycetes are potential microbes for the biological devulcanization of rubber products.
