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:

Vertical distribution and anaerobic biodegradation of polycyclic aromatic hydrocarbons in mangrove sediments in Hong Kong, South China.
TL;DR: The biodegradation experiment proved that the sediment collected at a depth of 10-15 cm harbored anaerobic PAH-degrading bacterial strains with some intrinsic potential to degrade mixed PAHs consisting of fluorene, phenanthrene, fluoranthene and pyrene under low oxygen and non-oxygen conditions.

Responses of Aromatic-Degrading Microbial Communities to Elevated Nitrate in Sediments
Meiying Xu,Zhili He,Qin Zhang,Jin Liu,Jun Guo,Guoping Sun,Jizhong Zhou,Jizhong Zhou,Jizhong Zhou +8 more
TL;DR: The genes involved in the degradation of several kinds of aromatic compounds were significantly enriched after nitrate injection, especially those encoding enzymes for central catabolic pathways of aromatic compound degradation, and most of the enriched genes were derived from nitrate-reducing microorganisms, possibly accelerating bioremediation of aromatic-contaminated sediments.

Anaerobic degradation of polycyclic aromatic hydrocarbons and alkanes in petroleum-contaminated marine harbor sediments.
TL;DR: Results demonstrate that a wide variety of hydrocarbon contaminants can be degraded under sulfate-reducing conditions in hydrocarbon-contaminated sediments, and suggest that it may be possible to use sulfate reduction rather than aerobic respiration as a treatment strategy for hydro carbon- Contaminated dredged sediments.

Equivalence of microbial biomass measures based on membrane lipid and cell wall components, adenosine triphosphate, and direct counts in subsurface aquifer sediments.
TL;DR: Assays of microbial cell components are validated by comparison with the classical direct count in at least one soil/sediment by using conversion factors determined on subsurface microorganism monocultures.

Degradation of phenanthrene, fluorene, fluoranthene, and pyrene by a Mycobacterium sp
TL;DR: In this paper, mycobacterium sp. strain BB1 was isolated from a former coal gasification site and was able to utilize phenanthrene, pyrene, and fluoranthene as sole sources of carbon and energy and to degrade fluorene cometabolically.

Degradation of polycyclic aromatic hydrocarbons by pure strains and by defined strain associations: inhibition phenomena and cometabolism
TL;DR: Six bacterial strains capable of using, as sole carbon and energy source, at least one of the following polycyclic aromatic hydrocarbons, naphthalene, fluorene, phenanthrene, anthracene, fluoranthene and pyrene, were isolated and strain associations were found efficient in relieving inhibition phenomena, including the toxic effect of naphhalene.
