Isolation of Halophilic Bacteria from Maharlu salt Lake - Iran and their evaluation for the production of bioactive compounds
Authors
Abstract:
Halophilic bacteria grow over a wide range of salt concentrations. In this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. A total of 50 water, sediments and soil samples were collected from Maharlu salt lake in southern region of Fars-Iran and subjected for isolation of the bioactive compound producing Halophilic bacteria. The results obtained indicated that out of all isolates, three strains could produce the bioactive compounds. The isolates were molecular (16SrRNA) identified as Bacillus licheniformis, Bacillus subtilis and Bacterium Culaeen. Furthermore, structural analysis of the bioactive compounds was carried out in order to achieve maximum information concerning to them. The results obtained illustrated the existence of glycoprotein in all the bioactive compounds. Although, Staphylococcus aureus, Aspergillusniger and Mucor…. were sensitive to all the bioactive compounds, Pseudomonas aeruginosa, Escherichia coli and Bacillus cereus were resistant to them. In addition, the bioactive compound producing isolated strains by Bacillus licheniformis and Bacillus subtilis showed antifungal activity against Aspergillusniger and mucor sp. In total, our finding illustrated that the maharlu salt lake might be considered a source of halophilic bacteria with potent activity for production of the bioactive compounds. In addition, isolation and characterization of these compounds culminate in the achievement of the new drugs.

full textIsolation of some bacteria for halophilic microbiome of Urmia Lake
Urmia Lake is the largest lake in the Iranian plateau and the second largest Salt Lake in the world. This study was conducted to identify hypersaline bacteria in the lake through the screening with molecular markers. For the molecular study of the bacterial microbiome of the lake, samples were collected from water, sludge and soil of the different parts of the lake during different seasons of 2...
full textThe isolation of halophilic urease-producing bacteria and the study of their nano-crystal production
Urease-producing bacteria can precipitate calcite nano-crystals by producing urease in the presence of urea and calcium. Calcite precipitation resulting from microbial activity is a process which causes cementation of soil particles in nature. The purpose of this study was to isolate urease-producing halophilic bacteria in order to precipitate calcite in saline soil. Natural samples, including ...

Screening and identification of moderately halophilic protease producing bacteria from different regions of Maharloo, a hypersaline lake in the southern area of Iran, were the objectives of this study. In the preliminary screening, 16 isolates exhibited proteolytic activity on saline skim milk agar. All isolates were able to grow comfortably in the media containing 7-15% of salt. Protease...
full textDiversity of Moderate Halophilic bacteria from Sambhr Salt Lake
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...
