Article history: Received on: 11/04/2016 Revised on: 09/05/2016 Accepted on: 24/06/2016 Available online: 29/10/2016 Drug resistance in microorganisms is an emerging phenomenon that poses challenges to public health and treatment. The reservoir of drug resistance genes found in the resistome of environmental isolates in aquatic saline systems has been augmenting continuously. The spread of drug...

An annotated selection of World Wide Web sites relevant to the topics in Microbial Biotechnology Industrial and environmental applications of halophiles Halophiles have traditionally been important in the food industry. More recently, they have become important for the production of b-carotene and ectoine. This paper describes a halophilic lipase that could be useful for the production of eicos...

Cultureable bacterial diversity of previously unexplored Siachen glacier, Pakistan, was studied. Out of 50 isolates 33 (66%) were Gram negative and 17 (34%) Gram positive. About half of the isolates were pigment producers and were able to grow at 4-37°C. 16S rRNA gene sequences revealed Gram negative bacteria dominated by Proteobacteria (especially γ-proteobacteria and β-proteobacteria) and Fla...

Halophiles are salt-loving organisms that inhabit hypersaline environments and are well equipped to balance the osmotic pressure of the environment and resist the denaturing effects of salts. Halophiles can be grouped as slightly, moderately or extremely halophilic, depending on their requirement for NaCl. Moderately halophilic bacteria are microorganisms able to grow optimally in media contain...

In a study of a lake having a higher concentration of salts than the Dead Sea, all of the heterotrophic bacteria isolated were aerobes; no strictly anaerobic strains were found. Ninety percent of the strains were euryhalines and ten percent were strict halophiles. The extreme halophiles belonged to the species Halobacterium trapanicum and Halococcus morrhuae.

BACKGROUND The extremely halophilic archaea are present worldwide in saline environments and have important biotechnological applications. Ten complete genomes of haloarchaea are now available, providing an opportunity for comparative analysis. METHODOLOGY/PRINCIPAL FINDINGS We report here the comparative analysis of five newly sequenced haloarchaeal genomes with five previously published one...

Extremely to slightly halophilic bacteria were tested for susceptibility to two sterilizing agents, peracetic acid (PAA) and ethylene oxide (ETO). PAA susceptibility was explored by two methods: an agar plate (constant pH of 7.2) and a filter strip (constant incubation period of 37 days); 100% susceptibility was obtained by both methods. The dosage (0.5 ml/min) was applied to a filter pad in a ...

the objective of this study was to isolate halophilic bacteria with the ability to produce intracellular or extracellular l-asparaginase. a total number of 120 halophilic bacteria were isolated from 17 different saline habitats of iran including salt lakes, wetlands, brine springs and deserts. among these, 68 were able to grow in the presence of 1.5 m nacl and 52 demonstrated the ability to gro...
