Abstract EN
Perchlorate (ClO4−) has several industrial applications and is frequently detected in environmental matrices at relevant concentrations to human health.
Currently, perchlorate-degrading bacteria are promising strategies for bioremediation in polluted sites.
The aim of this study was to isolate and characterize halophilic bacteria with the potential for perchlorate reduction.
Ten bacterial strains were isolated from soils of Galerazamba-Bolivar, Manaure-Guajira, and Salamanca Island-Magdalena, Colombia.
Isolates grew at concentrations up to 30% sodium chloride.
The isolates tolerated pH variations ranging from 6.5 to 12.0 and perchlorate concentrations up to 10000 mg/L.
Perchlorate was degraded by these bacteria on percentages between 25 and 10.
16S rRNA gene sequence analysis indicated that the strains were phylogenetically related to Vibrio, Bacillus, Salinovibrio, Staphylococcus, and Nesiotobacter genera.
In conclusion, halophilic-isolated bacteria from hypersaline soils of the Colombian Caribbean are promising resources for the bioremediation of perchlorate contamination.
