Soil microbial community dynamics and phenanthrene degradation as affected by rape oil application

▶ Rape oil application increased the total PLFA content and changed the microbial community composition, even when phenanthrene was added to the soil. ▶ The 13C PLFA profiles showed 13C enrichment for the PLFAs i14:0, 15:0, 18:0, 18:1ω5 and the fungal biomarker 18:2ω6,9 under rape oil application. ▶ Fungal PLFA growth was highest among detected all PLFAs, but its 13C incorporation was lower compared to the Gram-positive and Gram-negative bacteria PLFAs.
