Bacillus salexigens sp. nov. is proposed based on the characteristics of six moderately halophilic, grampositive, rod-shaped strains isolated from salterns and hypersaline soils located in different geographical areas of Spain. These strains were motile, formed endospores, were strictly aerobic, were catalase and oxidase positive, and contained peptidoglycan of the meso-diamlnopimelic acid type in their vegetative cell walls. The DNA base compositions of these strains ranged from 36.3 to 39.5 mol%, and these organisms constitute a homology group with levels of DNA-DNA homology ranging from 73 to 100%. The 16S rRNA sequence of strain C-20MoT, which was used as the representative strain of these isolates, groups with the 16S rRNA sequences of members of the genus Bacillus, and the highest level of similarity is 95.4%. The type strain is strain C-20Mo (= ATCC 700290 = DSM 11483 = CCM 4646).
嗜盐芽孢杆菌新种（Bacillus salexigens sp. nov.）是基于从西班牙不同地理区域的盐田和高盐土壤中分离出的6株中度嗜盐、革兰氏阳性、杆状菌株的特性而提出的。这些菌株具运动性，形成内生孢子，严格需氧，过氧化氢酶和氧化酶呈阳性，其营养细胞壁含有中-二氨基庚二酸型肽聚糖。这些菌株的DNA碱基组成范围为36.3至39.5摩尔%，这些微生物构成一个DNA-DNA同源性水平为73%至100%的同源群。菌株C-20MoT的16S rRNA序列用作这些分离株的代表菌株，它与芽孢杆菌属成员的16S rRNA序列聚类，最高相似性水平为95.4%。模式菌株为菌株C-20Mo（=ATCC 700290 = DSM 11483 = CCM 4646）。
