Jejubacter calystegiae KSNA2T, a moderately halophilic, endophytic bacterium isolated from beach morning glory (Calystegia soldanella), was determined to be novel species in new genus the family Enterobacteriaceae. To gain insights into genetic basis of salinity stress response strain we sequenced its genome using two complementary sequencing platforms (Illumina HiSeq and PacBio RSII). The cont...

The current study describes the extracellular hydrolytic activities of halophilic bacteria isolated from subterranean rock salt. The estimated number of grown colonies was approximately 3000 per gram of a rock salt on the surface of the medium MH containing 10% NaCl. The investigated strains, randomly selected from the colonies observed on the plate, showed at least one of the tested extracellu...

Sambhar Lake (Salt of Earth), the largest inland saline and alkaline lake of India is situated in the state of Rajasthan, and is referred in the epic Mahabharata. When full, it covers an area of 230 sq km. It lays some 60 km west of Jaipur, adjacent to the Salt Lake City. Flocks of flamingoes are attracted by the delicious spirulina algae that flourish when the water reaches a medium degree of ...

The halophilic γ-proteobacterium Halomonas elongata DSM 2581(T) thrives at high salinity by synthesizing and accumulating the compatible solute ectoine. Ectoine levels are highly regulated according to external salt levels but the overall picture of its metabolism and control is not well understood. Apart from its critical role in cell adaptation to halophilic environments, ectoine can be used ...

A Halomonas sp., a marine halophilic and oligotrophic bacterium, was grown on exudates of Dunaliella bardawil. The bacteria increased the solubility of Fe, thereby enhancing its availability to the algae. As a result, the algal growth rate increased. Because of these syntrophic relations, growth of the marine alga D. bardawil was facilitated at Fe levels that would otherwise induce Fe deficienc...

BACKGROUND Microbial culturomics represents an ongoing revolution in the characterization of environmental and human microbiome. METHODS By using three media containing high salt concentration (100, 150, and 200 g/L), the halophilic microbial culturome of a commercial table salt was determined. RESULTS Eighteen species belonging to the Terrabacteria group were isolated including eight moder...

We have explored the use of optical oxygen electrodes to study oxygenic photosynthesis and heterotrophic activities in crystallizer brines of the salterns in Eilat, Israel. Monitoring oxygen uptake rates in the dark enables the identification of organic substrates that are preferentially used by the community. Addition of glycerol (the osmotic solute synthesized by Dunaliella) or dihydroxyaceto...

Halophilic microorganisms derived from diverse thalassohaline and athalassohaline environments including marine estuaries, saline and soda lakes, inland solar salterns and acidic habitats are categorized as slight-, moderateand extreme halophiles according to their NaCl requirements. Taxonomic studies with culturable diversities of halophiles revealed that they belong to both Archaea and Bacter...

Microbial life can be found over a wide range of extreme conditions like high salinity, pH, temperature, pressure, light intensity, oxygen and nutrients. Halotolerant or halophilic microorganisms, are able to live in saline environments, offer potential applications in various fields of Biotechnology. The halotolerant or halophilic microorganisms are important for maintenance of soil condition ...

An experiment was conducted at the Indian Agricultural Research Institute, New Delhi (2017-18) to report identification of halophilic poly-ß-hydroxybutyrate (PHB) producing bacteria and optimization process parameters for maximum PHB recovery. The phylogenetic analysis classified isolates into bacterial phylum α, γ-Proteobacteria, Firmicutes. Halomonas sp. KB7 Stenotrophomonas maltophila B11 pr...
