Leaching of organic carbon from grassland soils under anaerobiosis

, 2020
The projected increase of extreme precipitation and freeze-thawing events may lead to frequent occurrence of anaerobiosis in upland soils, which has significant impacts on biogeochemical processes affecting soil carbon loss.

Fnr and ArcA Regulate Lipid A Hydroxylation in Salmonella Enteritidis by Controlling lpxO Expression in Response to Oxygen Availability

Frontiers in Microbiology, 2018
Lipid A is the bioactive component of lipopolysaccharide, and presents a dynamic structure that undergoes modifications in response to environmental signals. Many of these structural modifications influence Salmonella virulence. This is the case of lipid

Corrosion protection by anaerobiosis

Water Science and Technology, 2001
Biofilm-forming bacteria can protect mild (unalloyed) steel from corrosion. Mild steel coupons incubated with Rhodoccocus sp. strain C125 and Pseudomonas putida mt2 in an aerobic phosphate-buffered medium containing benzoate as carbon and energy source, underwent a surface reaction leading to the formation of a corrosion-inhibiting vivianite layer [Fe3(

Photosynthetic and Growth Responses of Arundo donax L. Plantlets Under Different Oxygen Deficiency Stresses and Reoxygenation

Frontiers in Plant Science, 2019
Promotion of nonfood species production to marginal, degraded lands abandoned by mainstream agriculture is affected by extremes of water availability (droughts and floods), which have increased in frequency and intensity and account for severe yield ...

Invertebrates at the Land-Sea Interface in a Climate Change World: Heatwaves, Floods, Fire and Ice. [PDF]

Glob Chang Biol
Diverse communities of coastal marine invertebrates living on rocky shores, mudflats, mangroves and saltmarsh occur at the interface between marine and terrestrial environments, where they are vulnerable to the combined impacts of extreme climatic events (ECEs) such as marine and atmospheric heatwaves, fire, flooding, hyposalinity and changes in ...

Bacillus cereus Fnr binds a [4Fe-4S] cluster and forms a ternary complex with ResD and PlcR

BMC Microbiology, 2012
Background Bacillus cereus is a facultative anaerobe that causes diarrheal disease in humans. Diarrheal syndrome may result from the secretion of various virulence factors including hemolysin BL and nonhemolytic enterotoxin Nhe.

The Many Facets of Hypoxia in Plants

Plants, 2020
Plants are aerobic organisms that require oxygen for their respiration. Hypoxia arises due to the insufficient availability of oxygen, and is sensed by plants, which adapt their growth and metabolism accordingly.
