Extracellular hydrolytic enzymes of halophilic bacteria isolated from a subterranean rock salt crystal
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...
متن کاملResearch Paper ISOLATION AND CHARACTERIZATION OF MODERATE HALOPHILIC Salinicoccus sp. PRODUCING EXTRACELLULAR HYDROLYTIC ENZYMES
A moderate halophilic bacterium was isolated from the brine samples of Sambhar salt lake, Rajasthan (India). The isolate formed pigmented colonies and the bacterial cells are motile, Coccoid, Gram positive, strictly aerobic, catalaseand oxidasepositive, ferments carbohydrates, while failed to utilize citrate as sole carbon source. The isolate grew in presence of 2-20% (w/v) NaCl and at pH 7-11,...
متن کاملHalophilic Bacteria as a Source of Novel Hydrolytic Enzymes
Hydrolases constitute a class of enzymes widely distributed in nature from bacteria to higher eukaryotes. The halotolerance of many enzymes derived from halophilic bacteria can be exploited wherever enzymatic transformations are required to function under physical and chemical conditions, such as in the presence of organic solvents and extremes in temperature and salt content. In recent years, ...
متن کاملCulturable diversity of halophilic bacteria in foreshore soils
Halophilic bacteria are commonly found in natural environments containing significant concentration of NaCl such as inland salt lakes and evaporated sea-shore pools, as well as environments such as curing brines, salted food products and saline soils. Dependence on salt is an important phenotypic characteristic of halophilic bacteria, which can be used in the polyphasic characterization of newl...
متن کاملDiversity of culturable halophilic sulfur-oxidizing bacteria in hypersaline habitats.
Unexpectedly high culturable diversity of moderately and extremely halophilic obligately chemolithoautotrophic sulfur-oxidizing bacteria (SOB) was discovered in the sediments of various hypersaline habitats, including chloride-sulfate lakes in Mongolia, Russia and Ukraine, a sea saltern in Slovenia and a deep-sea salt brine from the Mediterranean. Six different groups of halophilic SOB, includi...
