Draft Genome Sequences of Halobacterium sp. Strains KA-4 and KA-6, Two Extremely Halophilic Archaea Isolated from a Triassic Salt Deposit in Northern Ireland.

Here, we report the draft genome sequences of Halobacterium sp. strains KA-4 and KA-6. These extremely halophilic archaea were isolated from a Triassic halite deposit in Northern Ireland. Based on 16S sequence identity, they were deemed to be closely related strains of Halobacterium noricense but with some notable phenotypic differences.
