This investigation aimed to identify the bioremediation potential of Mn
2+
-resistant bacterial strains cultured from the Surya Kund hot spring, Yamunotri, Uttarakhand. In this study, eight heavy metal-resistant isolates belonging to two phyla, i.e.,
Firmicutes
and
Proteobacteria, were investigated for their Mn
2+
biosorption potential.
The metal tolerance potential of all the thermophilic bacterial strains was determined by MIC. Bioremediation assay of these metal-resistant strains was performed for Mn
2+
through the live and dead biomass of the bacterial cell. The evaluation of the bioremediation rate of metal ions through bacteria was done by AAS. All the selected bacterial strains were evaluated with effective biosorption rates for
Mn
2+
.
Acinetobacter sp.
LSN-10 (YII-1) has been showing the highest potential for the removal of Mn
2+
in both live (41.202%) and dead biomass (64.721%) conditions. The bioremediation rate of dead biomass was observed quite higher in comparison to bioremediation through live bacterial cells in the maximum number of isolates. This study may provide a new eco-friendly and cost-effective approach to dealing with metal toxicity. However, further investigation is needed to identify the most effective applications and potential limitations of this method.
