Effect of nitrate on respiration ofMentha arvensis

Biologia Plantarum, 1978
The supply of nitrate nitrogen caused a marked increase in the rate of respiration of Japanese mint. Sodium azide strongly inhibited the rate of respiration at all the nitrate levels, but the inhibition was more marked at higher levels. Besides this, inhibition caused by azide treatment was less marked in older and nitrogen deficient tissues than in ...

Engineering Nanoplatforms for Alzheimer's Disease Detection via Biomolecular Corona Proteomic and Lipidomic Profiling

Advanced Healthcare Materials, EarlyView.
Engineered nanoparticles capture disease‐specific biomolecular coronas that uncover hidden molecular features of Alzheimer's disease. Combined proteomic and lipidomic analyses reveal a characteristic shift in ribosomal machinery and energy metabolism, generating a multiomic fingerprint that supports accurate disease detection and opens new ...

The molybdate transport protein ModA regulates nitrate reductase activity to increase the intestinal colonization and extraintestinal dissemination of Klebsiella pneumoniae in the inflamed gut

Virulence
The mammalian intestine is a major site of colonization and a starting point of severe infections by Klebsiella pneumoniae. Inflammatory bowel disease (IBD) is an inflammatory disorder of the gut, and host-derived nitrate in IBD confers a luminal growth ...

Brucella spp. are facultative anaerobic bacteria under denitrifying conditions

Microbiology Spectrum, 2023
Bacteria of the genus Brucella are responsible for human and animal brucellosis worldwide and comprise the well-characterized, so-called classical species belonging to the core clade, with a host range limited to mammals, and the novel atypical strains ...

Towards the Anaerobic Production of Surfactin Using Bacillus subtilis

Frontiers in Bioengineering and Biotechnology, 2020
The anaerobic growth of B. subtilis to synthesize surfactin poses an alternative strategy to conventional aerobic cultivations. In general, the strong foam formation observed during aerobic processes represents a major obstacle. Anaerobic processes have,

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus

Advanced Healthcare Materials, EarlyView.
This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...

Simultaneous sulfate and nitrate reduction in coastal sediments

ISME Communications, 2023
The oscillating redox conditions that characterize coastal sandy sediments foster microbial communities capable of respiring oxygen and nitrate simultaneously, thereby increasing the potential for organic matter remineralization, nitrogen (N)-loss and ...

Detection of genes for membrane-bound nitrate reductase in nitrate-respiring bacteria and in community DNA [PDF]

FEMS Microbiology Letters, 2000
A nested PCR primed by four degenerate oligonucleotides was developed for the specific amplification of sequences from the narG gene encoding the membrane-bound nitrate reductase. This approach was used to amplify fragments of the narG gene from five Pseudomonas species previously shown to be able to express the membrane-bound nitrate reductase and ...
