Halobacillus halophilus, a moderately halophilic bacterium, accumulates a variety of compatible solutes including glycine betaine, glutamate, glutamine, proline, and ectoine to cope with osmotic stress. Non-targeted analysis of intracellular organic compounds using 1H-NMR showed that a large amount of trans-4-hydroxy-L-proline (Hyp), which has not been reported as a compatible solute in H. halo...

Actinomycetes are Gram-positive filamentous bacteria well known for the production of bioactive compounds. Recently, many halophilic habitats have been explored isolation actinomycetes that exhibit biotechnological potentials. In this investigation, a saline habitat Rajasthan, Sambhar Salt Lake (SSL) was selected to study population and Carboxy Methyl Cellulase (CMCase) by native isolates. A to...

Summary Production of Thai fish paste Ka‐pi‐plaa fermented using beardless barb, Cyclocheilichthys apogon was monitored. The physicochemical, microbiological and antioxidant properties were compared after each process, that is autolysis, salting, sun‐drying fermentation. Colour parameters L* decreased while a* b* increased during production ( P < 0.05). finished product presented an intense ...

The cellular adjustment of Bacteria and Archaea to high-salinity habitats is well studied and has generally been classified into one of two strategies. These are to accumulate high levels either of ions (the "salt-in" strategy) or of physiologically compliant organic osmolytes, the compatible solutes (the "salt-out" strategy). Halophilic protists are ecophysiological important inhabitants of sa...

The high world interest given to the researches concerning the study of moderately halophilic solvent-tolerant bacteria isolated from marine polluted environments is due to their high biotechnological potential, and also to the perspective of their application in different remediation technologies. Using enrichment procedures, I isolated two moderately halophilic Gram-negative bacterial strains...

Alkaline proteases producing halophilic bacteria isolated from Sambar Lake, Rajasthan were investigated for keratinolytic activity. The aim of this study was to optimize culture conditions for maximum enzyme production as well as characterization of proteases with keratinolytic action. Casein was used as sole carbon and nitrogen source for alkaline protease production at 37°C and 150 rpm. Highe...

Halophilic Martelella strain AD-3, isolated from highly saline petroleum-contaminated soil, can efficiently degrade polycyclic aromatic hydrocarbons (PAHs), such as phenanthrene and anthracene, in 3-5% salinity. Gentisic acid is a key intermediate in the microbial degradation of PAH compounds. However, there is little information on PAH degradation by moderately halophilic bacteria. In this stu...

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...

Rock salt represents a potential host rock formation for the final disposal of radioactive waste. The interactions between indigenous microorganisms and radionuclides, e.g. uranium, need to be investigated to better predict the influence of microorganisms on the safety assessment of the repository. Hence, the association process of uranium with two microorganisms isolated from rock salt was com...
