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...

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...

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...

Molecular evolution is the change of amino acid composition at locus specific positions of proteins for maintaining structural and functional integrity over long periods of time. In orthologous protein sets, adapted in different environmental conditions such as normal, high temperature and high ionic condition might have different or identical evolutionary characters. To understand the basis of...
