The biosorption mechanism is an alternative for chemical precipitation and ultrafiltration which have been employed to treat heavy metal contamination with a limited success. In the present study, three species of Bacillus which were isolated from solar salterns were screened for their detoxification potential of the heavy metals, lead, chromium, and copper, by biosorption. Biosorption potentia...

The genus Halorubrum is a member of the family Halobacteriaceae which currently has the highest number of described species (31) of all the haloarchaea. Here we report the draft genome sequence of strain V5, a new species within this genus that was isolated from the solar salterns of Cabo Rojo, Puerto Rico. Assembly was performed and rendered the genome into 17 contigs (N50 = 515,834 bp), the l...

The salinity responses of cyanobacteria, anoxygenic phototrophs, sulfate reducers, and methanogens from the laminated endoevaporitic community in the solar salterns of Eilat, Israel, were studied in situ with oxygen microelectrodes and in the laboratory in slurries. The optimum salinity for the sulfate reduction rate in sediment slurries was between 100 and 120 per thousand, and sulfate reducti...

The ascomycetous black yeasts Hortaea werneckii, Phaeotheca triangularis, and Trimmatostroma salinum are halophilic fungi that inhabit hypersaline water of solar salterns. They are characterized by slow, meristematic growth and very thick, darkly pigmented cell walls. The dark pigment, generally thought to be melanin, is consistently present in their cell walls when they grow under saline and n...

During the course of survey of halophilic microorganisms, a total of sixteen bacterial isolates were obtained from coastal solar salterns of Orissa and West Bengal, India. Morphological, physiological and biochemical characteristics of these isolates indicate that majority of them belong to the genus Halomonas, however, members belonging to Cobetia and Halococcus were not uncommon. These isolat...

BACKGROUND Hortaea werneckii is one of the most salt-tolerant species among microorganisms. It has been isolated from hypersaline waters of salterns as one of the predominant species of a group of halophilic and halotolerant melanized yeast-like fungi, arbitrarily named as "black yeasts". It has previously been shown that H. werneckii has distinct mechanisms of adaptation to high salinity envir...

The prokaryotic residents of the Tis solar saltern in the southeast of Iran on the shore of Oman Sea were investigated by the culture-dependent methods. Sequencing of the PCR-amplified fragments of 16S rRNA genes revealed that bacterial populations were related to Actinobacteria, Bacteroidetes, Balneolaeota, Firmicutes, and Proteobacteria. T...

Haloarchaea are the predominant microflora of hypersaline econiches such as solar salterns, soda lakes, and estuaries where the salinity ranges from 35 to 400 ppt. Econiches like estuaries and solar crystallizer ponds may contain high concentrations of metals since they serve as ecological sinks for metal pollution and also as effective traps for river borne metals. The availability of metals i...
