ACS Agricultural Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

The immobilization of beneficial bacteria using innovative techniques such as JetCutter has garnered attention in agriculture due to its high efficiency and production rate. This study focused on immobilizing Bacillus pumilus alginate hydrogels with enhance water retention soil plant biostimulant properties. Key operational parameters, bacterial viability, auxin production, microparticle effects were evaluated. Operating at 445 rpm a flow 6.55 g s–1 was critical for optimal matrix formation. resulting dried microparticles ranged from 0.52 0.99 mm size, capacity 67% w/w. After 180 days, the cell viability 2.61 × 109 CFU mL–1, average 162.02 208.94 μg g–1 without l-tryptophan, demonstrating effectiveness this technique maintaining activity. aimed developing biofertilizer based natural polymers tool, specifically context sustainable enhancing resilience water-deficit conditions, optimization microbial formulations. approach utilizing technology producing agricultural biofertilizers represents novel application that could production.

Rhizobium sp. as a Growth Inducer of Phaseolus vulgaris L., Determining the Qualitative Chemical Composition of Its Ethyl Acetate Extract Using High-Resolution Liquid Chromatography Coupled with Mass Spectrometry

International Journal of Plant Biology, Journal Year: 2025, Volume and Issue: 16(1), P. 37 - 37

Published: March 20, 2025

Phaseolus vulgaris L. is one of the most important legumes for human consumption due to its contents proteins, antioxidants, minerals, and bioactive compounds. In last decade, there has been a growing research interest in increasing yields while reducing or replacing use chemical fertilizers. This led focus on plant growth-promoting Rhizobacteria (PGPR) as biofertilizers sustainable agricultural practices. The aim this study was determine activity culture broth Gram-negative soil bacteria Rhizobium sp. (F7), which conserved Collection Beneficial Bacteria at Institute Fundamental Research Tropical Agriculture (INIFAT), identify main secondary metabolites present ethyl acetate crude extract using high-resolution liquid chromatography coupled with mass spectrometry (UHPLC-ESI-MS/MS). seeds evaluated. obtained by liquid–liquid extraction from broth, UHPLC-ESI-MS/MS used metabolites. results indicated that exhibited an vitro growth-stimulating effect. Furthermore, ten were identified (p-coumaric acid, indole-3-lactic naringenin, siderophores B C, among others). These findings highlight produced sp., bacterial strain INIFAT collection, have positive effect growth promoters plants. They reveal potential promising candidate inclusion management

Potential of Bacillus halotolerans in Mitigating Biotic and Abiotic Stresses: A Comprehensive Review

Stresses, Journal Year: 2025, Volume and Issue: 5(2), P. 24 - 24

Published: March 25, 2025

Bacillus halotolerans, a halophilic bacterial species of the genus Bacillus, is emerging as biological control agent with immense potential for sustainable agriculture, particularly in extreme conditions and environmental rehabilitation. This review summarizes current state research on B. emphasizing its diverse applications biocontrol plant pathogens, growth promotion under salinity stress, nematode management, bioremediation. halotolerans utilizes several mechanisms such production siderophores phytohormones, secretion exopolysaccharides, release antifungal nematicidal compounds, which allows it to mitigate both abiotic biotic stresses various crops, including wheat, rice, date palm, tomato, others. In addition, genomic metabolomic analyses have revealed secondary metabolite that improves antagonistic growth-promoting traits. Despite significant progress, challenges remain translating laboratory results into field applications. Future should focus formulating effective bioinoculants trials maximize practical utility agriculture resilience.
