The α-amylase-producing haloalkaliphilic archaeon sp. strain Ah-36 (T = type strain) was isolated previously from a Kenyan soda lake, Lake Magadi. Most cells of strain Ah-36 occurred in irregular clusters, and the colonies were orange-red. The polar lipids of this organism were composed of C, C and C, C derivatives of phosphatidylglycerol and phosphatidylglycerophosphate. Phosphatidylglycero-(cyclo-) phosphate, which is characteristic of , was not detected. The complete nucleotide sequence of the 16S rRNA gene revealed that the closest relative of strain Ah-36 is ATCC43101 (level of similarity, 96.4%), an extremely halophilic archaeon. However, strain Ah-36 did not exhibit a significant level of DNA homology to ATCC43101, which represents the only previously described species in the genus . We describe a new species for strain Ah-36, for which we propose the name .
