“…Very recently, however, ARAHAL et al (2002) have proposed that the genus Carnimonas should be included in this family. VREELAND et al (1980) originally described the genus Halomonas with only one species, H. elongata, but currently Halomonas includes 22 species, some of them previously assigned to other genera, such as Arthrobacter (COBET et al, 1970), Deleya (AKAGAWA and YAMASATO, 1989;BAUMANN et al, 1972;BAUMANN et al, 1983;QUESADA et al, 1984;VALDERRAMA et al, 1991) Flavobacterium (VOLCANI, 1940, Halovibrio (FENDRICH, 1988), Paracoccus (KOCUR 1984), Pseudomonas (ROSENBERG, 1983;HEBERT and VREELAND, 1987) and Volcaniella (QUESADA et al, 1990). Other species, however, have only been described more recently as members of the genus Halomonas (FRANZ- MANN et al, 1987;JAMES et al, 1990;BERENDES et al, 1996;ROMANO et al, 1996;MORMILE et al, 1999;DUCK-WORTH et al, 2000;BOUCHOTROCH et al, 2001;YOON et al, 2001;YOON et al, 2002 (ARAHAL et al, 2001a(ARAHAL et al, , 2001b.…”

Strain NCMB 1971, originally the type strain of Flavobacterium halmophilum, was isolated from the Dead Sea (B. Elazari-Volcani, Ph.D. thesis, Hebrew University, Jerusalem, Israel, 1940). Callies and Mannheim (2) suggested that this strain was not a Flavobacterium strain as, unlike true members of the genus Flavobacterium, it contained ubiquinones, not menaquinones, as the major respiratory quinones. Woese et al. (8) showed that strain NCMB 1971T (T = type strain) was phylogenetically related to Halomonas elongata. An analysis of the 16s rRNA catalogs of Deleya aesta NCMB 1980 (a synonym of Deleya aquamarina [l]) and Halomonas subglaciescola ACAM 12 indicated these organisms were phylogenetically related to H . elongata and strain NCMB 1971T; the four organisms formed a distinct cluster within the Proteobacteria, which led to the construction of a new family, the Halomonadaceae (4). Redetermination of the guanine-plus-cytosine content of the DNA of strain NCMB 1971T as 63 mol% by the thermal denaturation method and the phylogenetic link of this bacterium to members of the genus Halomonas suggested that it should be accommodated within this genus and that the species F. halmophilum should be formally transferred to the genus Halomonas as Halomonas halmophila (4, 5).The original phenotypic description of H . halmophila is scant, as expected for a description originating in the 1940s. H. halmophila NCMB 1971T was included as a reference strain in recent numerical taxonomic studies of halotolerant pigmented bacteria (S. J. Dobson, B.S. thesis, University of Tasmania, Tasmania, Australia, 1988) and nonpigmented bacteria (S. R. James, S. J. Dobson, P. D. Franzmann, and T. A. McMeekin, Syst. Appl. Microbiol., in press) isolated from Antarctic saline lakes. In these studies the phenotype of strain NCMB 1971T differed in some respects from the original description. The organism did not produce a yellow pigment, nor did it hydrolyze gelatin, but it did grow at 37"C, produced acid from glucose, sucrose, and maltose, and possessed a single lateral flagellum. The phenotypic description was also expanded. The report of the Ad Hoc Committee on Reconciliation of Approaches to Bacterial Systematics (7) recognized the need for phenotypic descriptions of distinct genospecies, and an updated description of H . halmophila is clearly required. The emended description of H . halmophila below draws on the results of previous phenotypic (Dobson, B.S. thesis), chemotaxonomic (3), and phylogenetic (4) studies.Emended description of Halomonas hahophila Franzmann, Wehmeyer, and Stackebrandt 1988.

“…This genus -currently one of the largest among the moderate halophiles -was originally proposed by Vreeland et al (1980) with a single species, Halomonas elongata. Currently, the genus comprises more than 20 species, including bacterial isolates from different terrestrial and aquatic environments with, in most cases, high salt concentrations.…”

A group of moderately halophilic bacteria able to degrade aromatic organic compounds contaminating hypersaline habitats in southern Spain have been isolated and characterized. The taxonomic position of these strains was determined using phenotypic, phylogenetic and genotypic methods. The G+C content of their DNA ranged from 61?0 to 62?9 mol%. DNA-DNA hybridization studies showed that they constitute a genospecies, having DNA-DNA hybridization values of 90-100 %. Analysis of the complete 16S rRNA gene sequence revealed a high level of similarity with members of the genus Halomonas, sharing 98 % 16S rRNA gene sequence similarity with the type strains of Halomonas salina and Halomonas halophila. However, phenotypic differences and the low level of DNA-DNA hybridization suggest the placement of these strains as a novel species within the genus Halomonas. The name Halomonas organivorans sp. nov. is proposed, with strain G-16.1 T (=CECT 5995 T =CCM 7142 T ) as the type strain. This novel species of Halomonas is characterized by its ability to use a wide range of organic compounds (benzoic acid, p-hydroxybenzoic acid, cinnamic acid, salicylic acid, phenylacetic acid, phenylpropionic acid, phenol, p-coumaric acid, ferulic acid and p-aminosalicylic acid), and it could be useful for the decontamination of polluted saline habitats.
