Benzo[a]pyrene and Benzo[k]fluoranthene in Some Processed Fish and Fish Products
In this study, the concentration levels of the probable carcinogenic PAH fractions, benzo[a]pyrene (BaP) and benzo[k]fluoranthrene (BkF) in fillets of some processed fish species were investigated. Fish species comprising Merluccius poli (hake), Tyrsites atun (snoek), Seriola lalandi (yellow-tail) and Brama brama (angel fish) were bought in fish shops at Gordon's Bay, Western Cape, South Africa...
متن کاملInhibition of Benzo(a)pyrene and Benzo(a)pyrene 7,8-Dihydrodiol Metabolism by Benzo(a)pyrene Quiñones1
Benzo(a)pyrene 1,6-, 3,6-, and 6,1 2-quinones were found to be noncompetitive inhibitors of mixed-function oxidation of benzo(a)pyrene (BP) and frans-7,8-dihydro-7,8-dihydroxybenzo(a)pyrene (BP 7,8-dihydrodiol). BP 6,1 2-quinone was the most potent inhibitor of both BP and BP-7,8-dihydrodiol oxi dation followed by BP 1,6-quinone and BP 3,6-quinone. The K, for inhibition of BP mixed-function oxi...

متن کاملOxidative Degradation of Benzo[a]pyrene by the Ligninolytic Fungi
A maximal degradation rate (76%) was obtained when Polyporus sp. S133 was cultured with 0.05% of tween 80, as compared to just 35% degradation in non-supplemented cultures. When fungus Polyporus sp. S133 was grown in presence of shitake’s nutrient, the degradation rate increased up to 69% as compared to just 56 and 40% degradation in glucose and polypeptone supplemented cultures. One metabolite...
متن کاملBenzo[a]pyrene degradation by Sphingomonas yanoikuyae JAR02.
Batch experiments were conducted to characterize the degradation of benzo[a]pyrene, a representative high molecular weight (HMW) polycyclic aromatic hydrocarbon (PAH), by Sphingomonas yanoikuyae JAR02. Concentrations up to the solubility limit (1.2 microg l(-1)) of benzo[a]pyrene were completely removed from solution within 20 h when the bacterium was grown on salicylate. Additional experiments...
