Genotyping of Halobacterium (Haloarchaeum) isolates using the DiversiLab repPCR system by Cleland et al. at the American Type Culture Collection [16]. The two sequenced Halobacterium species are included, the model strain NRC-1 (ATCC 700922) and strain R-1 (ATCC 29341) [14], which appear to differ sufficiently enough to warrant distinct species designations.
