Figure 1.
The degradation percentages of PAHs and derivatives by NarAaAb and NarA2B2 within the whole cells at 24 h. The green column represents E. coli BL21(DE3) containing pET28a-narAaAb and pACYCDuet-phdCD, and the orange column represents E. coli BL21(DE3) containing pETDuet-narA2-Ter-narB2 and pACYCDuet-phtAcAd. NAP, naphthalene (50 mg/L); PHE, phenanthrene (50 mg/L); FLN, fluorene (50 mg/L); ACE, acenaphthene (50 mg/L); ANT, anthracene (40 mg/L); DBT, dibenzothiophene (50 mg/L); DBF, dibenzofuran (50 mg/L); CA, carbazole (50 mg/L); BP, biphenyl (50 mg/L); PYE, pyrene (10 mg/L); FLU, fluoranthene (10 mg/L); BaA, benzo[a]anthracene (10 mg/L); CHR, chrysene (10 mg/L); BaP, benzo[a]pyrene (10 mg/L). The concentration in parentheses is the initial concentration. HMW-PAHs: PYE, FLU, BaA, CHR, and BaP.
