METAPROTEOMICS APPROACH FOR PROTEIN ANALYSIS OF HALOTOLERANT
Ayesha Ameen and Shahid Raza*
Halophiles have evolved two basic strategies to survive in salt stress conditions. In ‘compatible solute’ strategy, most of the halophilic bacteria cope with their external environments by accumulating small, highly water soluble organic compounds like glycine betaine, proline, glutamine, potassium, glutamic acid and ectoine. In ‘salt in’ strategy, bacterial and archaeal cells maintain internal environment by accumulating high concentrations of potassium chloride. Accumulation of different compatible solutes can stimulate the bacterial growth in salt stress conditions. Halophilic and halotolerant bacteria can also be used to degrade different organic compounds in bioremediation process.
