Anaerobic degradation of naphthalene by the mixed bacteria under nitrate reducing conditions.
TLDR
The results showed that the mixed bacteria could degrade nearly all the naphthalene over the incubations of 25 days when the initial naphthaene concentration was below 30 mg/L, and the degradation rates of nphthalene increased with increasing initial concentrations.About:

Anaerobic biodegradation of benzo(a)pyrene by a novel Cellulosimicrobium cellulans CWS2 isolated from polycyclic aromatic hydrocarbon-contaminated soil.
TL;DR: Cellulosimicrobium cellulans CWS2, a novel strain capable of utilizing benzo(a)pyrene (BaP) as the sole carbon and energy source under nitrate-reducing conditions, was isolated from PAH-contaminated soil and exhibited strong BaP degradation capability and has great potential in the remediation of BaP-/PAH- Contaminated environments.

Mingzi Shi,Xinyu Zhao,Longji Zhu,Junqiu Wu,Taha Ahmed Mohamed,Xu Zhang,Xiaomeng Chen,Yue Zhao,Zimin Wei +8 more
TL;DR: High-throughput sequencing revealed that enhanced denitrification effectively stimulated the metabolism of denitrifying microorganisms with aromatic-degrading capability, and co-occurring network analysis indicated that some keystone taxa of denitized microorganisms involved in the conversion of nitrate to nitrite were the most crucial for enhancingDenitrification and reducing aromatic HS formation.

Anaerobic Biodegradation of Pyrene by Paracoccus denitrificans Under Various Nitrate/Nitrite-Reducing Conditions
TL;DR: In this paper, the influence of denitrifying conditions on pyrene degradation in a pure culture was investigated, with a strain isolated from petrol-contaminated river sediment, treatments of pyrene biodegradations were set up using various ratios of nitrate to nitrite.
