Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

Plant Growth-Promoting Rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and enhance growth through various mechanisms. This study assessed the role of PGPR in sustainable agriculture. Bacterial isolates were collected from districts Kerala, followed by isolation screening. Out 90 strains, ten selected for comprehensive in vitro characterization, including morphological, biochemical molecular identification. LC-MS-TOF analysis identified 37 anti-phytopathogenic compounds positive mode 11 negative mode, confirming their strong biocontrol potential.These findings highlight potential to disease resistance, supporting eco-friendly agricultural practices.

Effective Microbial Strategies to Remediate Contaminated Agricultural Soils and Conserve Functions

Agronomy, Год журнала: 2024, Номер 14(11), С. 2637 - 2637

Опубликована: Ноя. 8, 2024

The growing global emphasis on sustainable agriculture has brought increased attention to the health and productivity of soils, especially through lens soil microbiology. Microbial communities in are essential for nutrient cycling, organic matter decomposition, maintaining overall health. However, agricultural practices, including synthetic fertilizers intensive farming, have led short time impacts these microbial ecosystems, potentially threatening fertility environmental quality. Agricultural expansion food production generate waste chemical inputs, such as heavy metals, pesticides, herbicides, leading significant contamination. This scenario requires implementation remediation strategies that both energy efficient. In this context, microbiological processes present a much promising approach mitigating pollution. Techniques bioremediation, which harness natural metabolic capabilities microorganisms, bioaugmentation, involves introduction specific strains increase degradation processes, being explored. These approaches vital restoring health, contributing conservation biodiversity, improving promoting long-term productivity.

Plant growth-promoting bacteria (PGPB) are considered a promising tool for triggering the synthesis of bioactive compounds in plants and to produce healthy foods. This study aimed demonstrate impact PGPB on growth, accumulation primary secondary metabolites, biological activities, nutritional qualities Eruca sativa (arugula), key leafy vegetable worldwide. To this end, Jeotgalicoccus sp. (JW0823), was isolated identified by using partial 16S rDNA-based identification phylogenetic analysis. The findings revealed that JW0823 significantly boosted plant biomass production about 45% (P<0.05) enhanced pigment contents 47.5% 83.8%. JW0823-treated showed remarkable improvements their proximate composition vitamin contents, with E levels increasing 161.5%. induced metabolites including antioxidants, vitamins, unsaturated fatty acids, essential amino thereby improving treated plants. An increase amounts acids recorded, isoleucine showing highest 270.2%. accompanied increased activity enzymes involved acid biosynthesis, glutamine synthase, dihydrodipicolinate cystathionine γ-synthase, phenylalanine ammonia-lyase enzymes. Consequently, total antioxidant antidiabetic activities inoculated were enhanced. Additionally, improved antimicrobial against several pathogenic microorganisms. Overall, treatment is highly method enhancing health-promoting properties characteristics E. sativa, making it valuable quality important vegetable.

Effect of Herbicide-Resistant Oil-Degrading Bacteria on Plants in Soil Contaminated with Oil and Herbicides

Plants, Год журнала: 2024, Номер 13(24), С. 3560 - 3560

Опубликована: Дек. 20, 2024

Biological remediation of agricultural soils contaminated with oil is complicated by the presence residual amounts chemical plant protection products, in particular, herbicides, which, like oil, negatively affect soil microbiome and plants. In this work, we studied five strains bacteria genera Pseudomonas Acinetobacter, which exhibited a high degree biodegradation (72–96%). All showed resistance to herbicides based on 2,4-D, imazethapyr tribenuron-methyl, ability fix nitrogen, phosphate mobilization, production indole-3-acetic acid. The pollutants affected growth-stimulating properties different ways. most promising strain P. citronellolis N2 was used alone together oat lupine plants for including herbicide-treated oil-contaminated soil. Combined contamination more toxic microorganisms. Bacterization stimulated formation chlorophyll suppressed synthesis abscisic acid malonic dialdehyde tissues. combined use effectively reduced content hydrocarbons (including herbicides). results obtained can be develop new methods bioremediation polychemical pollution.
