Enzymatic mechanisms involved in phenanthrene degradation by the white rot fungus Pleurotus ostreatus

Article Abstract:

The enzymatic mechanisms involved in phenanthrene degradation by white rot fungus Pleutrotus ostreatus was studied to determine its use as an alternative model for xenobiotic metabolism. The study made use of the hypothesis of isolation and identification of metabolic intermediates and suggested polycyclic aromatic hydrocarbon (PAH) degradation pathways. Results show that P. ostreatus utilizes a path way with components common to both ligninolytic and nonligninolytic fungi to degrade PAHs.

Degradation of the fluoroquinolone enrofloxacin by wood-rotting fungi

Article Abstract:

The brown wood-rot fungus Gloeophyllum striatum causes greater degradation of fluoroquinolone enrofloxacin, synthetic antimicrobial agent, as compared to white wood-rot fungi. The wood-rotting fungi present in a pure culture mineralizes the carbonyl group of enrofloxacin. The 14CO2 production by G. striatum is about 17% per week. However, the preadsorption of enrofloxacin to native or gamma ray-sterilized soil reduces the rate of 14CO2 production to 0.2% and 0.9% per week.

Comparison of phenanthrene and pyrene degradation by different wood-decaying fungi

Article Abstract:

Five different wood-decaying fungi were used in examining trhe phenanthrene and pyrene degradation. Pyrene and phenanthrene were incubated in liquid culture for 63 days and mineralized with Kuehneromyces mutabilis and Trametes versicolor, respectively. Results show that phenanthrene mineralization may also be achieved using L sulphureus and A aegerita. Results also suggest that fungi mineralization of both compounds is not dependent on the number of aromatic rings.
