Abstract
Degradation of styrene in the gaseous phase was investigated for white-rot fungi Pleurotus ostreatus (two strains), Trametes versicolor, Bjerkandera adusta and Phanerochaete chrysosporium. Fungi were grown in liquid culture and the gas/mycelium contact surface was enhanced with the help of perlite. The influence of various inducers on styrene degradation was studied. The best inducers for styrene degradation were lignosulphonate for P. ostreatus and T. versicolor and wood meal for B. adusta and P. chrysosoporium. Under these conditions all fungi were able to degrade styrene almost completely in 48 h at a concentration of 44 μmol/250 ml total culture volume; one strain of P. ostreatus was able to remove 88 μmol styrene under these conditions. Three transformation products of [14C]styrene in cultures of P. ostreatus were identified: phenyl-1,2-ethanediol, 2-phenylethanol and benzoic acid; 4% of the styrene was metabolised to CO2 in 24 h and no other volatile products were found.
