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(

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

Modification of pyruvate kinase and lactate dehydrogenase in foot muscle of the sea mussel Mytilus galloprovincialis under anaerobiosis and recovery

Brazilian Journal of Medical and Biological Research, 1997
The modification of pyruvate kinase (PK) and lactate dehydrogenase (LDH) activity in foot muscle of the mussel Mytilus galloprovincialis during exposure to air and recovery in water was investigated.

ArxA From Azoarcus sp. CIB, an Anaerobic Arsenite Oxidase From an Obligate Heterotrophic and Mesophilic Bacterium

Frontiers in Microbiology, 2019
Arsenic is a toxic element widely distributed in nature, but numerous bacteria are able to resist its toxicity mainly through the ars genes encoding an arsenate reductase and an arsenite efflux pump.

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.

Differential Gene Expression of Mucor lusitanicus under Aerobic and Anaerobic Conditions

Journal of Fungi, 2022
Mucor lusitanicus and some other members of the fungal order Mucorales display the phenomenon of morphological dimorphism. This means that these fungi aerobically produce filamentous hyphae, developing a coenocytic mycelium, but they grow in a multipolar

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.
