Genomic analyses of the three extremely halophilic archaea using next-generation sequencing

Extremely halophilic microorganisms have potentially valuable physiological properties to grow at high salt concentrations; they produce enzymes that have potential biotechnological applications. The three strains belonging to extremely halophilic archaea: Halorubrum halophilum B8^T, Halapricum salinum CBA1105^T and Halococcus sediminicola CBA1101^T, had been isolated from saline samples and their genomes were sequenced using a next-generation sequencing platform. The draft genomes of strain B8^T, CBA1105^T and CBA1101^T contain 3,677,984 bp, 3,451,492 bp and 3,764,367 bp, respectively, with G + C contents of more than 60% and include genomic information on various carbohydrate-active enzymes. A detailed comparative analysis with the haloarchaeal genome data will provide basic information on extremozymes produced by haloarchaea and opportunities for biotechnological applications of novel halophilic enzymes.
