Draft genome sequences of hydrocarbon degrading sp. AB510, sp. AB618 and sp. AB643 isolated from the estuarine sediments of Sundarban mangrove forests, India.

Unlabelled: The present study reports the draft genomes of three hydrocarbon-degrading haloarchaeal strains sp. AB510, sp. AB618 and sp. AB643 that were isolated from the estuarine sediments of Sundarban mangrove forests, India. All three genomes had a high GC content of around 60%, characteristic of the haloarchaea. The sp. AB510 genome was around 3.9 Mb in size and consisted of 4567 coding sequences and 54 RNAs. The sp. AB618 and sp. AB643 genomes were comparatively larger and around 4.8 Mb each. The AB618 and AB643 genomes comprised 5279 and 5304 coding sequences and 60 and 59 RNAs, respectively. All three of the genomes encoded several genes that attributed to their survival in the presence of hydrocarbons in their native habitats. Functional annotation and curation of the sequenced genomes suggested that the sp. AB510 strain utilized the gentisate pathway of aromatic compound degradation. While the sp. AB618 and sp. AB643 strains possessed the freedom of utilizing both the gentisate and the catechol pathways for degrading aromatic hydrocarbons.
