Little information is there on biodegradation of industrial pollutants by halotolerant rhizosphere microorganism. Moderate halophile microorganism has wide application in degradation of organic pollutants under moderate salt condition. Their potential to fully degrade harmful chemicals remain unexplored. Conventionally known mesophilic organisms are found incapable for efficient removal of pollutants in saline concentration. Halophile or halotolerant microorganism are different and adapted to low-extreme salt condition. Therefore, these microorganisms are capable of bioremediation of hydrocarbon, dyes and phenol under saline condition. The previous studies have shown that halophilic microorganism can eliminate polycyclic aromatic hydrocarbon, petroleum hydrocarbon and phenolic compounds. In the present review we discuss recently work done on degradation of hydrocarbon, phenols, heavy metals, azo dyes, pesticide such DDT, lindane by halotolerant rhizobacteria.
