Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Autotrophic denitrification (AuDen) is an efficient, convenient and eco-friendly biological
process for the treatment of nitrate-contaminated organic-deficient waters. AuDen can be …

Microorganisms can mediate arsenic (As) and antimony (Sb) transformation and thus
change the As and Sb toxicity and mobility. The influence of As and Sb on the innate …

Arsenic is the most prevalent environmental toxic element and causes health problems
throughout the world. The toxicity, mobility, and fate of arsenic in the environment are largely …

The biotransformation of arsenic is highly relevant to the arsenic biogeochemical cycle.
Identification of the molecular details of microbial pathways of arsenic biotransformation …

Hadal trenches are the deepest and most remote regions of the ocean. The 11-kilometer
deep Challenger Deep is the least explored due to the technical challenges of sampling …

The cultivation of bacteria is highly biased toward a few phylogenetic groups. Many of the
currently underexplored bacterial lineages likely have novel biosynthetic pathways and …

Arsenic is a metalloid whose name conjures up images of murder. Nonetheless, certain
prokaryotes use arsenic oxyanions for energy generation, either by oxidizing arsenite or by …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

Life at high salt concentrations is energetically expensive. The upper salt concentration limit
at which different dissimilatory processes occur in nature appears to be determined to a …
