Polycyclic aromatic hydrocarbon biodegradation by a subtropical white rot fungus in packed bed and suspended carrier bioreactor systems

摘要: Application of a biotreatment system utilising immobilised white rot fungi can become an alternative for treating water or effluent contaminated by organic pollutants such as polycyclic aromatic hydrocarbons (PAHs). The application the packed bed and suspended carrier bioreactor systems degradation PAHs in synthetic polluted media using subtropical fungal isolate DSPM95 was evaluated. isolate, could reduce mixture selected namely; fluorene, phenanthrene, anthracene, pyrene benzo(a)anthracene 50 to 96 % over reactor operation time 31 days when concentration each PAH feed medium 1 mg l−1. High manganese peroxidase laccase activities were detectable during biodegradation both systems, however maximum enzyme not be sustained bioreactors extended periods time. Varying concentrations glucose nutrient nitrogen help sust...
