toxic heavy metals, such as lead (pb) and cadmium (cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. twenty four moderately halophilic bacteria isolated from saline environments of iran were used to study their ability to bioremediation of lead and cadmium. amongst them, a gram-negative rod shaped bacterium, de...

Hypersaline environments are widely distributed on the earth s continent where they exist either as natural water bodies such as permanent saline lakes, ephemeral saltpans and salt marshes,or as artificial solar salterns (Litchfield and Gillevet; 2002). The microbial diversity of saline lakes has been studied primarily by focusing on the isolation and characterization of individual organisms wi...

Halophiles are extremophile organisms that thrive in environments with very high concentrations of salt. Halophiles are categorized as slight, moderate or extreme, based on the extent of their halotolerance. Slight halophiles prefer 0.3 to 0.8 M (1.8 to 4.7% seawater is 0.6 M or 3.5%), moderate halophiles 0.8 to 3.4 M (4.7 to 20%), and extreme halophiles 3.4 to 5.1 M (20 to 30%) NaCl. Halophile...

Microorganisms that love salt are known as halophiles, and they found in both the archaeal eubacterial domains of life. Halophiles do naturally occur mesmeric saline habitats such hypersaline lakes, pans, marshes, soils, solar salterns. The group microorganisms live a salty environment is halophilic microbiome. This includes bacteria, algae, fungi, viruses, more. According to how much can toler...

The genetic relatedness among various strains of halophilic bacteria has been assessed by deoxyribonucleic acid-deoxyribonucleic acid (DNA-DNA) duplex formation and ribosomal ribonucleic acid (RNA) hybridization. All of the strains of extremely halophilic rods are closely related, and the extent of divergence of base sequence is similar for the major and minor DNA components. Parallel experimen...

Halopiger goleamassiliensis strain IIH3(T) sp. nov. is a novel, extremely halophilic archaeon within the genus Halopiger. This strain was isolated from an evaporitic sediment in El Golea Lake, Ghardaïa region (Algeria). The type strain is strain IIH3(T). H. goleamassiliensis is moderately thermophilic, neutrophilic, non-motile and coccus-shaped. Here we describe the features of this organism, t...

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 as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while synthesizing or accumulating organic sol...

sequence is similar for the major and minor DNA components. Parallel experiments with ribosomal RNA revealed a relationship between the extremely halophilic rods and cocci and a more distant relationship to moderate halophiles and to a photosynthetic extreme halophile. Renaturation studies of halophile DNA exclude the possibility that the satellite DNA represents multiple copies of a small epis...
