Abstract
Environments with high-salt concentrations are often populated by dense microbial
communities. Halophilic microorganisms can be isolated from different saline environments
and different strains even belonging to the same genus have various applications.
Wastewater and soil rich in both organic matter and salt are difficult to treat using
conventional microorganisms typically found in wastewater treatment and soil bioremediation
facilities. Studies on decontaminative capabilities and decontamination pathways of
organic contaminants (i.e., aromatic compounds benzoate, cinnamate, 3-phenylpropionate,
4-hydroxybenzoic acid), heavy metals (i.e., tellurium, vanadium), and nutrients in
the biological treatment of saline wastewater and soil by halophilic microorganisms
are discussed in this review.
