Synthesis of glycine betaine from exogenous choline in the moderately halophilic bacterium Halomonas elongata
(American Society for Microbiology, 1998)
The role of choline in osmoprotection in the moderate halophile Halomonas elongata has been examined. Transport and conversion of choline to betaine began immediately after addition of choline to the growth medium. ...

Osmoprotectants in Halomonas elongata: High-affinity betaine transport system and choline-betaine pathway
(American Society for Microbiology, 1996)
The osmoregulatory pathways of the moderately halophilic bacterium Halomonas elongata DSM 3043 have been investigated. This strain grew optimally at 1.5 to 2 M NaCl in M63 glucose-defined medium. It required at least 0.5 ...

Development of a gene reporter system in moderately halophilic bacteria by employing the ice nucleation gene of Pseudomonas syringae
(American Society for Microbiology, 1995)
The expression of the ice nucleation gene inaZ of Pseudomonas syringae in several moderate halophiles was investigated to establish its utility as a reporter for promoter activity and gene expression studies in these ...

Role of Nγ-acetyldiaminobutyrate as an enzyme stabilizer and an intermediate in the biosynthesis of hydroxyectoine
(American Society for Microbiology, 1999)
Strain CHR63 is a salt-sensitive mutant of the moderately halophilic wild-type strain Halomonas elongata DSM 3043 that is affected in the ectoine synthase gene (ectC). This strain accumulates large amounts of N')'-acetyl ...

Isolation and characterization of salt-sensitive mutants of the moderate halophile Halomonas elongata and cloning of the ectoine synthesis genes
(American Society for Biochemistry and Molecular Biology Inc., 1997)
The moderate halophile Halomonas elongata Deustche Sommlung fur Mikroorganismen 3043 accumulated ectoine, hydroxyectoine, glutamate, and glutamine in response to osmotic stress (3 M NaCl). Two Tn1732-induced mutants, CHR62 ...

Numerical taxonomy of heavy metal-tolerant nonhalophilic bacteria isolated from hypersaline environments
(1998)
A total of 232 metal-tolerant bacterial strains were isolated from water and sediment samples collected in different hypersaline environments located in Cádiz, Huelva and Morón de la Frontera (Spain). They were isolated ...

Biology of moderately halophilic aerobic bacteria
(American Society for Microbiology, 1998)
The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such ...
