Abstract

Microorganisms that live their life in places with high salt concentrations are known as Halophiles. Halophilic bacteria play a majority role in hypersaline environments than other microorganisms. These Halophiles are having intense strategies of adaptation and tolerate them to sustain their survival in the saline extreme, such adaptation in hypersaline environments makes them to give unique attention to the researcher for their biological properties. The diversity of halophiles bacteria incorporates aerobic and anaerobic phototrophs, aerobic heterotrophs, fermenters, denitrifies, sulfate reducers, and methanogens. The biotechnological important of the halophilic bacteria, such as producing a Novel bioactive compounds, industrially important enzyme, Bio-surfactants, Stabilizers Exopolysacharides, Probiotics etc. Secondary metabolites are organic compounds produced by bacteria, fungi, or plants which are not directly involved in the normal growth, development, or reproduction of the organism. Some common examples of secondary metabolites include ergot alkaloids, antibiotics, naphthalenes, nucleosides, phenazines, quinolines, terpenoids, peptides, and growth factors.
