BaP-degrading microbial community
Sequencing libraries were generated using usingTruSeq DNA PCR-Free Sample Preparation Kit (Illumina, USA) following manufacturer's recommendations. The library quality was assessed on the Qubit@ 2.0 Fluorometer (Thermo Scientific) and Agilent Bioanalyzer 2100 system. At last, the library was sequenced on an Ion S5 TM XL  platform and 600 bp paired-end reads were generated.
