Impact of Copper on the Physiology and Transcriptome of Methylosinus Trichosporium OB3b Grown on Either Methane or Methanol

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Methylosinus trichosporium OB3b can grow on methanol in the absence but not presence of copper due: (1) overgeneration of reducing power from methanol oxidation; (2) formate accumulation leading to acidification of the growth medium and inactivation of formate dehydrogenase; and (3) lack of expression of potential oxidative stress defence genes ...

Genome Size and Complexity in Azotobacter chroococcum

Microbiology, 1984
All of eight strains of Azotobacter chroococcum examined contained between two and six plasmids ranging from 7 to more than 200 MDal in size. Strain MCC-1, a derivative of NCIMB 8003, was cured of various of the four largest of its five plasmids and the phenotypes of the strains compared. all fixed nitrogen and exhibited uptake hydrogenase activity.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Sodium-Dependent Growth of Azotobacter chroococcum [PDF]

Applied and Environmental Microbiology, 1986
The majority of Azotobacter chroococcum strains in a collection obtained from Alberta soils were absolutely dependent on Na + for growth. Two strains from the American Type Culture Collection also were either Na + dependent or were stimulated by Na +

Microbial Inoculation Strategies for Optimal Cherry Tomato Production

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT The use of microorganisms is a promising technique in agriculture to provide greater water and nutrient efficiency for crops. The objective of this study was to evaluate the effects of microbial inoculation on plant growth, fruit yield and fruit quality of cherry tomatoes (Solanum lycopersicum var. cerasiforme) in a protected environment.

Strategies for Enhancing Resilience in Horticultural Crops Against Combined Abiotic Stresses

Physiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT Horticultural crops are increasingly exposed to simultaneous abiotic stresses such as drought, salinity, and temperature extremes, which often exacerbate each other's effects, leading to severe yield and quality losses. Addressing these multifaceted challenges necessitates the development and application of integrated and innovative strategies.

Enhancing polyamide fabric performance through green reduction of graphene oxide for superior ultraviolet protection and electrical conductivity

Coloration Technology, Volume 141, Issue 1, Page 26-43, February 2025.
Abstract In this study, a polyamide warp‐knitted fabric was treated with a graphene oxide (GO) aqueous dispersion using a laboratory‐type Jigger dyeing machine. Subsequently, the GO underwent a chemical reduction process, employing rosehip extract powder as a nature‐based reducing agent. The effect of reduction time (12 and 24 h) was investigated.

Soil inoculation with nitrogen‐fixing bacteria to supplement maize fertilizer need

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract Nitrogen (N) is an essential plant nutrient, but low and variable plant‐available N levels in agricultural soils often limit maximum grain production. The objective of this study was to determine if a free‐living nitrogen‐fixing bacterial inoculant (NFI) could supply biologically‐fixed N as an additional N source and if this enhances maize ...
