Arsenic contamination in aquatic and terrestrial ecosystem is a serious environmental issue.
Both natural and anthropogenic processes can introduce it into the environment. The …

Arsenic (As) is a metalloid that occurs widely in the environment. The biological oxidation of
arsenite [As (III)] to arsenate [As (V)] is considered a strategy to reduce arsenic toxicity and …

Symbiotic bacteria, commonly called rhizobia, lead a saprophytic lifestyle in the soil and
form nitrogen-fixing nodules on legume roots. During their lifecycle, rhizobia have to adapt to …

Arsenic is a ubiquitous toxic metalloid, the concentration of which is beyond WHO safe
drinking water standards in many areas of the world, owing to many natural and …

The family Rhizobiaceae includes many genera of soil bacteria, often isolated for their
association with plants. Herein, we investigate the genomic diversity of a group of …

Arsenic contamination of drinking water affects more than 140 million people worldwide.
While toxic to humans, inorganic forms of arsenic (arsenite and arsenate), can be used as …

A freshwater photosynthetic arsenite‐oxidizing bacterium, Cereibacter azotoformans strain
ORIO, was isolated from Owens River, CA, USA. The waters from Owens River are elevated …

以湖南石门雄黄尾矿污染土壤为对象, 研究纵向不同深度, 横向不同距离土样中的重金属污染
程度以及细菌群落结构变化规律, 查明砷污染土壤的核心微生物组成并将其与土壤理化指标进行 …

Fluoride (F) and arsenic (As) are two major contaminants of water and soil systems around
the globe, causing potential toxicity to humans, plants, animals, and microbes. These …

In environments where arsenic and microbes coexist, microbes are the principal drivers of
arsenic speciation, which directly affects bioavailability, toxicity and bioaccumulation …
