“…To circumvent these limitations, the microbiological As(III) oxidation has been proposed as an eco-friendly alternative to conventional chemical pre-treatment methods (Bahar et al 2013 ). Several As(III)-oxidising microorganisms have been recovered in various As-rich environments including geothermal sites, soils, sediments, mine, arsenical pesticides and smelter-impacted sites (Engel et al 2013 ; Fazi et al 2016b ; Heinrich-Salmeron et al 2011 ; Lami et al 2013 ; Paul et al 2018 ; Quéméneur et al 2008 , 2010 ; Satyapal et al 2018 ; Sultana et al 2012 ; Thul et al 2019 ). The As(III) oxidation is a detoxification process in heterotrophic bacteria (Bahar et al 2012 ; Muller et al 2003 ; Vanden Hoven and Santini 2004 ), or an energetic metabolism in chemolithoautotrophic microorganisms, such as Rhizobium NT-26 and T. arsenivorans (Battaglia-Brunet et al 2006 ; Garcia-Dominguez et al 2008 ; Hoeft et al 2007 ; Santini et al 2000 ).…”

Owing to their roles in the arsenic (As) biogeochemical cycle, microorganisms and plants offer significant potential for developing innovative biotechnological applications able to remediate As pollutions. This possible use in bioremediation processes and phytomanagement is based on their ability to catalyse various biotransformation reactions leading to, e.g. the precipitation, dissolution, and sequestration of As, stabilisation in the root zone and shoot As removal. On the one hand, genomic studies of microorganisms and their communities are useful in understanding their metabolic activities and their interaction with As. On the other hand, our knowledge of molecular mechanisms and fate of As in plants has been improved by laboratory and field experiments. Such studies pave new avenues for developing environmentally friendly bioprocessing options targeting As, which worldwide represents a major risk to many ecosystems and human health.

“…The microbe Micrococcus sp. KUMAs15 could also remove As from the culture medium in a laboratory condition by surface adsorption as well as arsenic accumulation at the environmentally relevant concentration of As; the results have been earlier reported [12]. The present study aimed to validate the possible pathogenic effect of the isolated arsenic-decontaminating bacterium on human cell lines.…”

“…A highly As-resistant microbial isolate has been previously reported from our laboratory. The microbial isolate is designated as KUMAs15 identified as a strain of Micrococcus [12] following 16SrDNA sequencing and analysis of homology by the NCBI BLAST function [13] and Ribosomal Database Project [14]. The isolated microbial strain has shown arsenite [As(III)] oxidation capability, by accelerating the spontaneous conversion of As (III) to a less toxic form arsenate [As(V)] [15] which could be removed from water with ease due to its lower solubility than As (III) [16,17].…”

Background: An arsenic-resistant microbial strain, Micrococcus sp. KUMAs15 isolated from West Bengal, India, has demonstrated high resistance to arsenic due to its arsenic accumulation and adsorption ability, establishing the strain as a potential arsenic bioremediation candidate for arsenic-contaminated niche. The successful field application of the microbe necessitates evaluation of probable immunotoxicological reactions on human cells. The present study determines expression profiles of pro-inflammatory and anti-inflammatory cytokines in cells exposed to KUMAs15. Results: The present study explored the alterations in expressions of the pro-inflammatory and anti-inflammatory cytokines in two human cell lines exposed to KUMAs15. The expression profile of the cytokine genes demonstrated that Micrococcus sp. KUMAs15 does not significantly induce inflammatory effects in these human cell lines. The upregulated expression of IL-8 and downregulated expression of IL-6 were observed in HaCaT. The HepG2 have shown downregulated IL-12 gene expression. These observations indicate the non-pathogenicity of KUMAs15 on the human cell lines. Conclusion: The observations from the study extend the applicability of the arsenic-resistant Micrococcus sp. KUMAs15 for environmental arsenic decontamination. The isolate KUMAs15 was observed to be non-pathogenic to the human cell lines, as the strain does not initiate inflammatory reactions in these cell lines.

“…It could be due to the interference in phosphate transport system for the uptake of arsenic leading to the extension of logarithmic growth. Paul et al, also reported a growth response of KUMAs15 at different concentrations of arsenate and arsenite with lengthened lag phase but the maximum growth obtained for KUMAs15 was after 28-30h of incubation (Paul et al 2018).…”

Arsenic (As) is a quintessential toxic metalloid and it has been classified as Group 1 human carcinogen. The evolution of arsenic defense mechanisms due to the omnipresent nature of arsenic has resulted in its alteration to less toxic forms. The present study deals with the isolation of arsenic remediating microbial strains from soil samples and their integration into bioremediation strategy. From the metal contaminated site, 118 different bacterial strains were isolated from heavy metal contaminated site. Twenty-five strains were tolerant to arsenic and one bacterial strain Enterobacter cloacae (RSC3) demonstrated maximum growth at high concentration of arsenate (6000ppm). The cell growth kinetics of RSC3revealed the specific growth rate (µ) to be 0.55 h-1. The The bacteria hosts arsC gene in the genome involved in the reduction of arsenate to arsenite. AAS, SEM, TEM and EDX studies confirmed the arsenate transportation and efflux of arsenic by the bacteria. Furthermore, the strain showed multi-resistance to other heavy metals like zinc, cadmium, selenium and nickel and several antibiotics indicating its application for facilitating bioremediation of toxic metal contaminated sites.
