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.

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.

Biodegradation of Three- and Four-Ring Polycyclic Aromatic Hydrocarbons under Aerobic and Denitrifying Conditions
TL;DR: Evidence for the biodegradation of three- and four-ringed PAHs (anthracene, phenanthrene, and pyrene) under strict anaerobic, denitrifying conditions is presented.
Journal ArticleDOI
Identical ring cleavage products during anaerobic degradation of naphthalene, 2-methylnaphthalene, and tetralin indicate a new metabolic pathway.
TL;DR: The series of identified metabolites suggests that anaerobic degradation of naphthalenes proceeds via reduction of the aromatic ring system of 2-naphthoic acid to initiate ring cleavage in analogy to the benzoyl-coenzyme A pathway for monoaromatic hydrocarbons.
