Ecotoxicological assessment of PAHs and their dead-end metabolites after degradation by Mycobacterium sp. strain SNP11

Isolation of polycyclic aromatic hydrocarbons (PAHs)-degrading Mycobacterium spp. and the degradation in soil

“…Actually, Mycobacterium species have been frequently reported as four-ring PAHs degraders, such as M. vanbaalenii PYR-1 [21], Mycobacterium sp. RJGII-135 [22], A1-PYR [23], LP1 [24] and SNP11 [25]. It has been established that the particular cell wall layer of mycobacteria, such as mycolic acids, is important for the degradation of hydrophobic compounds [26].…”

Fungal Bioremediation of Creosote-Treated Wood: A Laboratory Scale Study on Creosote Components Degradation by Pleurotus ostreatus Mycelium

“…After preliminary tests carried out with the negative (solvent control) and positive controls (Phenol standard in the range 5.7-45.6 mg/L), methanol extracts of T 1 A, T 2 B, T 2 C and control T 0 A were diluted with water (initial dilution 4%) and analysed in duplicate. The toxicity of the samples was estimated as EC 50 values on the basis of a dose/response curve (Pagnout et al 2006).…”

“…Mycelia were grown on a wheat straw bed to which chipped CTW was added in different amounts. As carcinogenic substances may be formed during PAH biotransformation in living organisms (Pagnout et al 2006) an accurate analytical study was carried out on the effectiveness of biodegradation and the possible persistence of oxidation products. The results of chemical analyses were compared to ecotoxicological tests.…”

Mycobacterium as Polycyclic Aromatic Hydrocarbons (PAHs) Degrader

“…showed a significant reduction of genotoxic potential after biodegradation of pyrene, fluoranthene, and phenanthrene [20,31,32].…”
