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.

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 ...

Efficacy of Organic Soil Conditioners for Barley (Hordeum vulgare) Production in Arid Regions

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
Introduction Barley cultivation in arid regions can be enhanced through deficit irrigation, which reduces water usage while minimizing yield loss. This method maximizes water‐use efficiency, making barley suitable for areas with limited water resources. Objective. To evaluate the effects of different soil amendments on improving barley production under

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 ...

Impacts of Azotobacter Inoculation on Hybrid Maize Growth and Yield in Midhill of Lamjung, Nepal

International Journal of Agronomy, Volume 2025, Issue 1, 2025.
In recent times, the need for the replacement of chemical‐based nitrogen fertilizers has arisen due to various economic, soil sustainability, and availability issues. Thus, the use of biological nitrogen fixation microbes as biofertilizers has gained prominence. A field experiment was conducted in Lamjung campus to assess the efficacy of Azotobacter as
