“…E. coli, Bacillus idriensis, and Sphingomonas desiccabilis are engineered species for As bioremediation [72]. Some fungi, including Rhizobium sp., Rhizopus sp., Trichoderma sp., Aspergillus flavus, and Penicillium canescens, are As bioremediators too [63,73]. Moreover, some yeasts like Saccharomyces cerevisiae can reduce arsenate by ArsC (Figure 7), a protein that has As reductase activity.…”

Nowadays, pollution of the environment is a huge problem for humans and other organisms’ health. Conventional methods of pollutant removal like membrane filtration or ion exchange are not efficient enough to lower the number of pollutants to standard levels. Biological methods, because of their higher efficiency and biocompatibility, are preferred for the remediation of pollutants. These cost-effective and environment-friendly methods of reducing pollutants are called bioremediation. In bioremediation methods, enzymes play the most crucial role. Enzymes can remedy different types of organic and inorganic pollutants, including PAHs, azo dyes, polymers, organocyanides, lead, chromium, and mercury. Different enzymes isolated from various species have been used for the bioremediation of pollutants. Discovering new enzymes and new subtypes with specific physicochemical characteristics would be a promising way to find more efficient and cost-effective tools for the remediation of pollutants.

“…Arsenic is a metalloid with high toxicity, which can be found in the environment in geological substrata, whereas it can also be released by human activities [1]. In numerous areas, arsenic in freshwater atmosphere, due to direct release from anthropogenic and natural sources, is a severe concern [2].…”

Water is a valuable compound for plants, animals, and humans. Various contaminating agents pollute it, with arsenic being one of them. Measurements of arsenic in potable water in Upper Sindh were conducted during this study. The samples were prepared by microwave-assisted digestion and analyzed by an atomic absorption spectrophotometer. A total of 240 potable water samples were collected from 8 Talukas of Upper Sindh. DMS coordinates were also recorded with the help of the Global Positioning System (GPS). The highest arsenic content of 50µg/L was observed in Garhi Khairo Taluka. The average arsenic content in water samples of all of the Talukas, except Miro Khan, was found higher than the WHO permissible limit. The 69.2% of samples were found to be contaminated by arsenic. Therefore, the water of the studied area is concluded to be in poor condition for cooking and drinking.
