“…138 Three major modes of arsenic biotransformation occurred in the environment: redox transformation between As( iii ) and As( v ), the reduction and methylation of As, and the bioproduction of organ arsenic compounds. 8,139–141 Arsenic contamination with sources in water 142–169 of some locations over the world are summarized in Table 3. Concentration range of As in water samples around the world is illustrated in Fig.…”

“…177,178 Nonetheless, in other cases this contamination is a consequence of mining operations, which, for instance, have led to As contents of up to 8250 mg L −1 in surface waters of Ghana and Togo. 164,166 Likewise, in Latin America, the population of various countries, including Argentina, Bolivia, Brazil, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Peru, and Uruguay 15, 143,144,[147][148][149]152,154,156,157,163,180 are facing problems with As contaminated water too (see Table 3).

“…In Asia, countries such as India, Bangladesh, China, Pakistan, and Vietnam, evidence high concentrations of As contamination. In Africa, elevated As concentrations have been reported in both the surface and groundwater (Mudzielwana et al, 2020). In Latin America, the estimated population at risk of As exposure exceeds ~14 million people, with hundreds of recorded cases of exposure in countries such as Chile, Argentina, and Mexico (Castrejón et al, 2020;Muñoz et al, 2016;Osuna-Martínez et al, 2020).…”

Isolation and molecular identification of native As-resistant bacteria: As(III) and As(V) removal capacity and possible mechanism of detoxification

et al. 2022

The study of arsenic resistant microorganisms with high arsenic removal capacity is fundamental for the development of economically sustainable technologies for the treatment of water contaminated with this metalloid. In this work, the isolation and identi cation of 4 native strains was carried out.: Rhodococcus gordoniae, Microbacterium hydrocarbonoxydans, Exiguobacterium indicum and Pseudomonas kribbensis . R.gordoniae was identi ed as the bacterium with the highest growth capacity in both As(III) and As(V). E.indicum removed about 74.8% of Arsenate, As(V), and 61.7% of Arsenite , As(III), while R.gordoniae removed about 81.6 % of As(III), and 77.2% of As(V), while that M.hydrocarbonoxydans was able to remove up to 79.9% of As(III) and 68.9% of As(V). Finally, it was observed that P. kribbensis removed about 80.2% of As(V). This study also contributes to the possible detoxi cation mechanisms employed by these bacteria, the knowledge of which could be crucial in the successful implementation of in situ bioremediation programs.
