Compared with Phanerochaete chrysosporium, Pleurotus ostreatus caused a significantly higher decrease in the average molecular weight (M-w) of most of the copolymers and the homopolymer under the applied culture conditions. However, the M-w, of poly (guaiacol/AAm) increased significantly during incubation with Pl ostreatus. P chrysosporium was able to reduce only the Mw of the poly(LS/AA) to a significant degree and not that of the other polymers. The mineralization rate of AAm and AA copolymers and terpolymers of AAm, AA and phenolics (LS, 3,4-DHBA, guiacol), which were tested with R ostreatus and Trametes versicolor, turned out to be low (0.8-3.2%). While the rates of mineralization were similar among all polymers, the decrease in radioactivity from the culture media was higher with the terpolymers bearing phenolic sites. UV spectra of the culture media revealed that the phenolic sites in the terpolymers were significantly degraded by both fungi. Obviously, the degradation of phenolics within the polymer chain caused a higher decrease in M-w but did not significantly increase the mineralization rate."],["dc.identifier.doi","10.1007/s00253-004-1668-5"],["dc.identifier.isi","000224302000017"],["dc.identifier.pmid","15257422"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/47569"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0175-7598"],["dc.title","Degradation of acrylic copolymers by white-rot fungi"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The effect of initiator concentration and the lignin/monomer ratio on the yield and (M) over bar(w) of enzymatically grafted polymers were studied.

The polymers tested were either homopolymers or copolymers containing lignin sulfonate, guaiacol or 3,4-dihydroxylbenzoic acid, respectively. Acrylamide copolymers (PAAm) were degraded faster than polymers of acrylic acid (PAA). Among the PAAm, the copolymers of lignin sulfonate and guaiacol were degraded at a significantly higher rate than the corresponding homopolymer, whereas among the PAA, the rate of degradation was highest with copolymers of guaiacol and 3,4-dihydroxylbenzoic acid. The decrease of H2O2, i.e. the rate of hydroxyl radical production in the presence of a certain polymer, did not correlate with the rate of its degradation. It was concluded that the incorporation of lignin and certain phenolic compounds into an acrylic chain may accelerate the decay of these polymers by wood decaying fungi, which reportedly produce hydroxyl radicals extra-cellularly, and through the use of advanced oxidation systems applied in sewage cleaning.
