Effect of coexisting metal ions on bio-precipitation of Cu2+ phosphate by Rahnella sp. LRP3 and its stability in soil

Plant, Soil and Environment, 2021
The phosphate precipitation of heavy metal induced by microorganisms plays an important role in immobilising heavy metal in soil. However, there is little knowledge about the effect of coexisting metal ions on the induction of Cu phosphate mineral and ...

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

Plant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Fate of Nitrogen During Metabolism of Whey Lactose by Rahnella aquatilis

Journal of Dairy Science, 1999
The rate of intake of peptides and free amino acids by Rahnella aquatilis was studied, as well as the evolution of concentrations of exopolysaccharide, biomass, and several metabolites. For this purpose, eight wheybased fermentation media were tested: hydrolyzed bovine whey under 1) aerobic and 2) anaerobic conditions; hydrolyzed bovine whey with 3) 2 ...

Urinary tract infection due to Rahnella aquatilis in a renal transplant patient [PDF]

Journal of Clinical Microbiology, 1992
Rahnella aquatilis is an unusual gram-negative rod belonging to the family Enterobacteriaceae. It inhabits fresh water and is rarely isolated from clinical specimens. We report the case of a urinary tract infection caused by this organism in a renal transplant patient.

Characterization of Levansucrase fromRahnella aquatilisJCM-1683

Bioscience, Biotechnology, and Biochemistry, 1992
Levansucrase (EC 2.4.1.10) was purified to homogeneity from cell-free extracts of Rahnella aquatilis JCM-1683 by streptomycin treatment, ammonium sulfate fractionation, and HPLC with a DEAE-Toyopearl pak 650M, TSKgel G-3000SW, and TSKgel DEAE-5PW. The enzyme had optimum activity around pH and 55—60°C.

Biological Control of Grape Crown Gall byRahnella aquatilisHX2 [PDF]

Plant Disease, 2007
Crown gall induced by Agrobacterium vitis is a worldwide plant disease in grape-growing regions. Rahnella aquatilis HX2, a new isolate from vineyard soil in Beijing, showed a significant inhibition effect on the development of crown galls in grapevines. In field trials, immersion of the basal ends of grape cuttings with HX2 cell suspension inhibited or

The Volatile Pentadecane From Bacillus Alleviates Plant Iron Deficiency Through Activating the Reduction‐Based Fe Uptake System

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1564-1577, March 2026.
ABSTRACT Iron (Fe) is an essential micronutrient for plant growth and development. Rhizosphere microorganisms play crucial roles in plant Fe nutrition, yet the underlying mechanisms remain largely unknown. Here, we assessed the effect of the volatile organic compounds (VOCs) produced by Bacillus velezensis SQR9 on Fe uptake in Arabidopsis, elucidated ...
