TL;DR: The new species is proposed, based on the characteristics of 29 strains of halotolerant, nonpigmented bacteria isolated from an Antarctic, hypersaline, meromictic lake, and has the following distinguishing features: cytochrome oxidase positive, no growth at 37°C, and glucose and other sugars are not utilized for growth.
Abstract: Halomonas subglaciescola sp. nov. is proposed, based on the characteristics of 29 strains of halotolerant, nonpigmented bacteria isolated from an Antarctic, hypersaline, meromictic lake. These strains and three reference strains of halotolerant bacteria were tested for 92 attributes. The data were analyzed by numerical taxonomic procedures. The new isolates did not cluster with the three reference strains, which included the type strain of Halomonas elongata. However, some of the isolates did share the following attributes which are characteristic of members of the genus Halomonas: a guanine-plus-cytosine content of 60.9 ± 1.0 to 62.9 ± 0.7 mol%, halotolerancse, largely oxidative mode of metabolism, motility, and peritrichous flagellation. The following are distinguishing features of the new species: cytochrome oxidase positive, no growth at 37°C, and glucose and other sugars are not utilized for growth. The type strain is strain ACAM 12 (= UQM 2926). The species has two biovars; biovar I contains motile strains and is represented by the type strain, and biovar II contains nonmotile strains and is represented by strain ACAM 21 (= UQM 2927).

TL;DR: It is concluded that the relationship between Halomonas elongata ATCC 33173T and “Pseudomonas halodurans” ATCC 29686T had 79% phenotypic similarity, indicating that these organisms are probably separate species of the same genus.
Abstract: Several strains of halotolerant bacteria from North America were compared for 125 characteristics. Although these organisms had several characteristics in common, they are a relatively heterogeneous group. The 12 strains could be divided into at least three and perhaps as many as five taxa. Halomonas elongata ATCC 33173T (T = type strain) and “Pseudomonas halodurans” ATCC 29686T had 79% phenotypic similarity, indicating that these organisms are probably separate species of the same genus. We conclude that this relationship is sufficient to warrant assignment of “Pseudomonas halodurans” to the genus Halomonas as Halomons halodurans sp. nov., nom rev., comb nov.
