Identification of a Novel Haloarchaeal Species <i>Halorubellus amylolyticus</i> sp. nov., Isolated from Salt Crystals of Salted Seaweed Knots and Genomic Insights into Genus <i>Halorubellus</i>.

ABSTRACT: An extremely halophilic archaeon named strain PRR65^T was isolated from a salt crystal of salted seaweed knots which were purchased from a supermarket in Wuhu, China. It exhibited an ability to hydrolyze starch. Strain PRR65^T is a coccus. Its growth range and optimum concentration for NaCl are 2.0-5.1 M and 3.4 M, respectively, and it requires magnesium ions (with an optimum concentration of 0.01 M). Homology search of the 16S rRNA gene sequence indicated that strain PRR65^T shows the highest sequence similarities with Halorubellus salinus GX3^T (96.97%). The basic growth conditions and many other physicochemical characteristics of strain PRR65^T are distinct from those of other species within its genus. The average nucleotide ident
