Anaerobic biodegradation of aromatic hydrocarbons by microbial enrichment cultures from mangrove sediments

Petroleum contamination in coastal sediments poses persistent ecological and human-health risks, particularly under anoxic conditions where the fate of both aliphatic hydrocarbons and high-molecular-weight PAHs remains poorly constrained. n-docosane (C22), pristane (Pr), phenanthrene (Phe), fluoranthene (FLT) or benzo[a]pyrene (BaP) are hydrocarbons found in petroleum complex pollutants.
