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 …

Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Net-zero emission and self-sustaining carbon-neutral have been widely encouraged and
intensively explored in wastewater treatment, as the wastewater industry accounts for …

Nitrogen is an essential component of all living organisms and the main nutrient limiting life
on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric …

Methane-dependent nitrate and nitrite removal in anoxic environments is thought to rely on
syntrophy between ANME-2d archaea and bacteria in the genus 'Candidatus …

Methane is a key compound in the global carbon cycle that influences both nutrient cycling
and the Earth's climate. A limited number of microorganisms control the flux of biologically …

Anammox-mediated systems have attracted considerable attention as alternative cost-
effective technologies for sustainable nitrogen (N) removal from wastewater. This review …

Background Soil microbiomes play an important role in the services and functioning of
terrestrial ecosystems. However, little is known of their vertical responses to restoration …

The recent recovery of genomes for organisms from phyla with no isolated representative
(candidate phyla) via cultivation-independent genomics enabled delineation of major new …

Methane is the final product of the anaerobic decomposition of organic matter. The
conversion of organic matter to methane (methanogenesis) as a mechanism for energy …
