“…Environmental HM pollution in soil and water reduces crop production and can be detrimental to health safety through food chains owing to industrial solid waste, and agricultural inputs such as fertilizers and pesticides. These persistent environmental contaminants are non-degradable and can only be transformed into other harmless forms, such as Hg, Cd, As, Cr, Tl, Pb, Mn, and Ni, which cause severe toxic effects in living organisms [ 4 , 5 , 6 , 7 , 8 ]. Fe, Cu, Co, and Zn are essential HMs that act as coenzymes in biological processes and are less toxic at low concentrations [ 9 ].…”

Rapid industrialization has led to the pollution of soil and water by various types of contaminants. Heavy metals (HMs) are considered the most reactive toxic contaminants, even at low concentrations, which cause health problems through accumulation in the food chain and water. Remediation using conventional methods, including physical and chemical techniques, is a costly treatment process and generates toxic by-products, which may negatively affect the surrounding environment. Therefore, biosorption has attracted significant research interest in the recent decades. In contrast to existing methods, bacterial biomass offers a potential alternative for recovering toxic/persistent HMs from the environment through different mechanisms for metal ion uptake. This review provides an outlook of the advantages and disadvantages of the current bioremediation technologies and describes bacterial groups, especially extremophiles with biosorbent potential for heavy metal removal with relevant examples and perspectives.

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.

“…In the Bhojpur district of Bihar, two gram-positive bacteria, Bacillus infantis and Bacillus litoralis, were reported in 2018 for their ability to oxidize arsenite to arsenate (Biswas and Sarkar 2019). This oxidation process helps in the detoxi cation of arsenite.…”

Arsenic is a metalloid that is naturally present in the environment. Exposure to arsenic can cause health issues like cancer, cardiovascular, neurological, and respiratory complications. With more than a million people affected due to arsenic contamination in groundwater, Bihar is one of the worst arsenic-affected states in India. Groundwater is one of the primary sources for cooking, farming, and other household chores. People are exposed to arsenic through food as well as contaminated drinking water. As a result, arsenic has made its way into the food chain. Several cases of cancer, arsenical dermatosis, and keratosis have been reported in Bihar. The source of arsenic contamination in Bihar has yet to be identified, although the Himalayan sediments have been suspected as one of the prime reasons. The government has taken steps to prevent and control arsenic contamination in the state; however, reports in recent years indicate the number of blocks affected by arsenic contamination has been rapidly increasing. This necessitates a more comprehensive arsenic mitigation tool. Various technologies can be employed to mitigate levels of arsenic in groundwater, of which bioremediation is one of the more cost-effective and sustainable methods. The current article is an attempt to give an overview of the sources and areas of Bihar with arsenic contamination, and the concentration in different regions. It also provides a piece of detailed information on arsenic contamination on health, and the current state of arsenic bioremediation.
