of halotolerance in microorganisms can be applied to organism growth and ecosystem dynamics in increasingly saline environments. Halotolerance can be applied to pollution and climate change; processes of halotolerance may be implemented to limit the damages of pollution.

Some halotolerant microorganisms are able to use light energy to generate proton and chloride gradients which allows bioenergetic processes to occur. The light-transducing protein, bacteriorhodopsin, allows this pathway to occur
