Bioremediacija z organskimi biocidi zaščitenega lesa z glivami bele trohnobe : diplomsko delo (univerzitetni študij)

Pirnat, Gašper (avtor), Pohleven, Franc (mentor), Humar, Miha (recenzent)

Glive, ki okužijo in razkrojijo impregniran les, lahko uporabimo za bioremediacijo - razgradnjo oz. razstrupitev polutantov iz določenega okolja. Glive bele trohnobe lahko razgradijo tudi organske biocide z ligninu podobno kemijsko strukturo. Uporabili smo 4 vrste gliv: Gloeophyllum trabeum, Hypoxlon fragiforme, Pleurotus ostreatus ter Trametes versicolor. Z njimi smo inokulirali petrijevke s papirčki, prepojenimi z različnimi koncentracijami (20; 6,595; 2,175; 0,717; 0,236 ter 0,078 mmol/L) Lindana, natrijevega pentaklorofenolata, Permetrina ter polikloriranega bifenila. Ugotovili smo, da organske biocide najbolje razkraja Trametes versicolor, najslabše pa Pleurotus ostreatus. Permetrin ter poliklorirani bifenil sta se pokazala kot lažje, Lindan ter natrijev pentaklorofenolat pa kot težje razgradljiva organska biocida.

Izvleček

Wood decay fungi can be used in bioremediation - detoxification of pollutants from specific environment. White-rot fungi are able to bioremediate some of organic pollutants, because their chemical structures are similar to lignine. 4 wood decay fungi: Gloeophyllum trabeum, Hypoxlon fragiforme, Pleurotus ostreatus and Trametes versicolor were used. Agar plates with paper discs were impregnated with different concentrations (20; 6.595; 2.175; 0.717; 0.236 and 0.078 mmol/L) of organic biocides - Lindane, sodium pentachlorofenolate, Permetrin and polychlorinated biphenyl were afterwards inoculated with those fungi. Trametes versicolor was found as the best fungi for bioremediation of organic biocides, Pleurotus ostreatus showed the worst results. Permetrin and polychlorinated biphenyl were more, while Lindane and sodium pentachlorofenolate less bioremedegradable.
