Degradation of phenanthrene and pyrene in contaminated soil by immobilized Zoogloeasp. and Fusarium sp.
【Abstract】 Immobilized with PVA,sodium alginate and activated carbon,both Zoogloea sp. and Fusarium sp.strains could degrade phenanthrene and pyrene efficiently.The optimal carrier was made of 100ρ·g -1 L PVA,5 sodium alginateρ·g -1 L and 50 activated carbon ρ·g -1 L.The degradation rates of phenanthrene and pyrene in 10 days were 87.48% and 75.34% by the immobilized bacterium,37.04% and 20.85% higher than those by the free bacterium,and the rates in 15 days were 84.36% and 74.87% by the immobilized fungus,5.35% and 11.23% higher than those by the free fungus.
