Proteome Response of Staphylococcus xylosus DSM 20266T to Anaerobiosis and Nitrite Exposure

Frontiers in Microbiology, 2018
The viability and competitiveness of Staphylococcus xylosus in meat mostly depend on the ability to adapt itself to rapid oxygen and nutrients depletion during meat fermentation.

Avaliação da porosidade e placa férrica de raízes de arroz cultivado em hipoxia Evaluation of porosity and iron plaque on rice roots grown under hypoxia

Revista Brasileira de Ciência do Solo, 2010
A alta difusividade do oxigênio em diversos materiais dificulta a criação e, ou, manutenção de um ambiente livre de O2. As técnicas utilizadas são pouco eficientes na exclusão do O2 e, portanto, não expressam a condição do solo alagado.

Inducing the Alternative Oxidase Forms Part of the Molecular Strategy of Anoxic Survival in Freshwater Bivalves

Frontiers in Physiology, 2018
Hypoxia in freshwater ecosystems is spreading as a consequence of global change, including pollution and eutrophication. In the Patagonian Andes, a decline in precipitation causes reduced lake water volumes and stagnant conditions that limit oxygen ...

Difficulties Associated with Small-Scale Production of Carbonic Maceration Wines

Fermentation, 2022
The aim of the work was to study the vinification by carbonic maceration carried out in small volume tanks, because the use of these deposits is necessary in scientific studies where repetitions are mandatory.

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 ...

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.
