Halophiles are salt loving organisms requiring about 3M5M NaCl concentration in their growth. Eleven halophilic archaea and nine bacteria were isolated from various samples from extremely high salt concentrated ecosystem from western parts of Maharashtra, India. The isolates were studied using morphological and biochemical studies. Most of the isolates were gram negative in nature. These organi...

BACKGROUND Generally, extremophiles have been deemed to survive in the extreme environments to which they had adapted to grow. Recently many extremophiles have been isolated from places where they are not expected to grow. Alkaliphilic microorganisms have been isolated from acidic soil samples with pH 4.0, and thermophiles have been isolated from samples of low temperature. Numerous moderately ...

The microbial loop is the conventional model by which nutrients and minerals are recycled in aquatic eco-systems. Biochemical pathways in different organisms become metabolically inter-connected such that nutrients are utilized, processed, released and re-utilized by others. The result is that unrelated individuals end up impacting each others' fitness directly through their metabolic activitie...

The to-date studies on extreme halophiles were focused on shake flask cultivations. Bioreactor technology with quantitative approaches can offer a wide variety of biotechnological applications to exploit the special biochemical features of halophiles. Enabling industrial use of Haloferax mediterranei, finding the optima of cultivation parameters is of high interest. In general, process paramete...

Some of the most commonly occurring but difficult to isolate halophilic prokaryotes, Archaea as well as Bacteria, require or prefer pyruvate as carbon and energy source. The most efficient media for the enumeration and isolation of heterotrophic prokaryotes from natural environments, from freshwater to hypersaline, including the widely used R2A agar medium, contain pyruvate as a key ingredient....

Halophilism has been of considerable interest since the report of Farlow (1880) on the reddening of salted fish. Any industry using either a salt packing process or a salt brine must be concerned with the control of halophiles. Considerable work has been done, therefore, with the isolation, identification, and control of these organisms. Stuart, Frey, and James (1933), Gibbons (1936), Lefevre a...
