Alcanivorax belongs to the hydrocarbonoclastic group of bacteria that are known for their preferential growth on alkanes and other related compounds. Here we report the genomic features of Alcanivorax marinus strain NMRL4 (=MCC 4632) isolated from oil polluted seawater of the Arabian Sea. Its 4,062,055 bp genome with 66.1% GC content encodes for 3935 coding sequences. The genome annotations of strain NMRL4 revealed the presence of multiple hydrocarbon degradation genes suggestive of its wider hydrocarbon substrate range. The strain encodes for three alkane monooxygenases, two cytochrome P450 and two flavin binding monooxygenases for degradation of short and long-chain alkanes. The genome shows capabilities for scavenging of nutrients, biofilm formation at oil-water interfaces, chemotaxis, motility and habitat specific adaptation. The genomic insights showed that the strain NMRL4 is an ideal candidate for bioremediation of pollutant petroleum hydrocarbons from the marine environment.
