TLDR
Halotolerant microorganisms play an essential role in food biotechnology for the production of fermented food and food supplements and the degradation or transformation of a range of organic pollutants and theproduction of alternative energy are other fields of applications of these groups of extremophiles.Abstract:
Halotolerant or halophilic microorganisms, able to live in saline environments, offer a multitude of actual or potential applications in various fields of biotechnology. The technical applications of bacteriorhodopsin comprise holography, spatial light modulators, optical computing, and optical memories. Compatible solutes are useful as stabilizers of biomolecules and whole cells, salt antagonists, or stress-protective agents. Biopolymers, such as biosurfactants and exopolysaccharides, are of interest for microbially enhanced oil recovery. Other useful biosubstances are enzymes, such as new isomerases and hydrolases, that are active and stable at high salt contents. Halotolerant microorganisms play an essential role in food biotechnology for the production of fermented food and food supplements. The degradation or transformation of a range of organic pollutants and the production of alternative energy are other fields of applications of these groups of extremophiles.read more

Microbial production of surfactants and their commercial potential.
JD Desai,Ibrahim M. Banat +1 more
TL;DR: Biosurfactants are more effective, selective, environmentally friendly, and stable than many synthetic surfactants, and the most promising applications are cleaning of oil-contaminated tankers, oil spill management, transportation of heavy crude oil, enhanced oil recovery, recovery of crude oil from sludge, and bioremediation of sites contaminated with hydrocarbons, heavy metals, and other pollutants.
