主 题:Aspergillus sydowii Anthracene Biodegradation Polycyclic aromatic hydrocarbons
摘 要:The present study investigated the efficiency of Aspergillus sydowii strain bpol(GenBank Accession Number:MK373021)in the removal of anthracene(100 mg/L).Optimal degradation efficiency(98.7%)was observed at neutral pH,temperature(30℃),biomass weight(2 g)and salinity(0.2%w/v)within 72 *** enzyme analyses revealed 131%,107%,and 89%induction in laccase,lignin peroxidase,and manganese peroxidase respectively during anthracene ***,the degradation efficiency(99.8%)and enzyme induction were significantly enhanced with the addition of 100 mg/L of citric acid and glucose to the *** varying anthracene concentrations(100-500 mg/L),the degradation rate constants(K1)peaked with increasing concentration of anthracene while the half-life(t1/2)decreases with increase in anthracene *** of fit(R2=0.976 and 0.982)was observed when the experimental data were subjected to Langmuir and Temkin models respectively which affirmed the monolayer and heterogeneous nature exhibited by *** cells during *** distinct metabolites;anthracene-1,8,9(2H,8aH,9aH)-trione,2,4adihydronaphthalene-1,5-dione,l,3,3a,7a-tetrahydro-2-benzofuran-4,7-dione and 2-hydroxybenzoic acid was obtained through Gas Chromatography-Mass spectrometry(GC-MS).*** exhibited promising potentials in the removal of PAHs.
