show Abstracthide AbstractCobetia sp. strain MM1IDA2H-1 is a hydrocarbon-degrading biosurfactant producer marine bacterium (HDMB) isolated from seawater samples obtained form Pacific Ocean in Chile. The strain MM1IDA2H-1 uses dibenzothiophene (DBT) as the sole carbon and energy source, shares the highest sequence similarity to the strain Cobetia marina DSM 4741, nevertheless, strain MM1IDA2H-1 showed phenotypic differences. Since the strain Cobetia sp. MM1IDA2H-1 with specific requirement of sodium to grow and able to use DBT as the sole carbon, we propose that this microorganism as a hydrocarbon-degrading bacterium indigenous to marine ecosystem. Cobetia sp. strain MM1IDA2H-1 produces biosurfactants in response to hydrocarbons or biological competitors. The genome of Cobetia sp. MM1IDA2H-1 was sequenced, processed, assembled and annotated for comprehensive applied studies.
