Optimising carbon and nitrogen sources for Azotobacter chroococcum growth [PDF]

, 2013
The present work deals with selecting and optimization of carbon and nitrogen sources for producing biomass from Azotobacter chroococcum. Four carbon sources (glucose, sucrose, manitol and sodium benzoate) and four nitrogen sources (yeast extract, meat ...

The Production of Gram-positive Variants by Azotobacter chroococcum [PDF]

Journal of General Microbiology, 1957
SUMMARY: Cultures of Azotobacter chroococcum isolated by four independent operators regularly produced Gram-positive forms, from which typical cultures of A. chroococcum were recovered under controlled conditions. This observation appears to confirm those of earlier workers, and is in accordance with the theory that the aerobic and anaerobic nitrogen ...

Formation of Fragile Cysts by a Strain of Azotobacter Chroococcum [PDF]

Journal of General Microbiology, 1969
SUMMARY: A strain of Azotobacter chroococcum (designated A. chroococcum NTS) which produces fragile cysts was isolated from soil. Fragility of the cysts was measured by ultrasonic treatment and compared to the fragility of cysts of a typical strain of A. chroococcum.

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 ...
