The present study investigated the shift in bacterial community structure in response to NP attenuation in the Gulf of Finland bottom sediments. High levels of NP_s (300 mg/kg) in sediments can be biodegraded by the autochthon microorganisms. NP_s addition showed no impact on diversity of microbial community structure. However, NP_s amendment led to significant change in bacterial community structure in NP_s amended microcosm. Illumina MiSeq sequencing analysis indicated that Firmicutes, Gammaproteobacteria, Deltaproteobacteria were the three most abundant bacterial groups in NP_s-degrading sediment, suggesting that these groups might have a specific role in NP_s degradation. The involvement of a wide range of microorganisms related to NP_s biodegradation enlarges the possible risk of reduction of NP_s in environment.
