Diversity of the cell-wall associated genomic island of the archaeon Haloquadratum walsbyi.

Abstract excerpt

BACKGROUND: Haloquadratum walsbyi represents up to 80% of cells in NaCl-saturated brines worldwide, but is notoriously difficult to maintain under laboratory conditions. In order to establish the extent of genetic diversity in a natural population of this microbe, we screened a H. walsbyi enriched metagenomic fosmid library and recovered seven novel version of its cell-wall associated genomic island. The fosmid...
