Abstract The increased dependence of farmers on chemical fertilizers poses a risk to soil fertility and ecosystem stability. Plant growth-promoting rhizobacteria (PGPR) are at the forefront sustainable agriculture, providing multiple benefits for enhancement crop production health. Bacillus subtilis is common PGPR in that plays key role conferring biotic abiotic stress tolerance plants by induced systemic resistance (ISR), biofilm formation lipopeptide production. As part bioremediating technologies, spp. can purify metal contaminated soil. It acts as potent denitrifying agent agroecosystems while improving carbon sequestration process when applied regulated concentration. Although it harbours several antibiotic genes (ARGs), reduce horizontal transfer ARGs during manure composting modifying genetic makeup existing microbiota. In some instances, affects beneficial microbes rhizosphere. External inoculation B. has both positive negative impacts endophytic semi-synthetic microbial community. Soil texture, type, pH bacterial concentration play crucial regulation all these processes. amendments consortia produced engineering could be used lessen effect diversity. complex plant–microbe interactions decoded using transcriptomics, proteomics, metabolomics epigenomics strategies which would productivity well-being more attributes similar character Dr. Jekyll plant growth, health environment akin Mr. Hyde.

Frass derived from black soldier fly larvae treatment of biodegradable wastes. A critical review and future perspectives

Waste Management, Год журнала: 2022, Номер 142, С. 65 - 76

Опубликована: Фев. 14, 2022

Inadequately treated biodegradable waste is considered an environmental, social and economic threat worldwide, which call for great attention. Waste treatment with larvae of the black soldier fly (BSF, Hermetia illucens) complies concepts circular economy, as it enables transformation these wastes into marketable products, closing loops promoting circularity. The processing residues (frass) constantly generated in management facilities large volumes, this product can be used organic fertilizer agriculture, stimulating a transition to economy. However, many aspects related frass are still unknown, such its varying composition nutrients, microorganisms bioactive compounds, post-processing requirements improved biological stabilization, behavior soil action plants' metabolism, among other aspects. In review article, we highlight potential from BSF world market regarding possible use fertilizer, summarize recent results novel point towards future research perspectives.

The Role of Beneficial Microorganisms in Soil Quality and Plant Health

Sustainability, Год журнала: 2022, Номер 14(9), С. 5358 - 5358

Опубликована: Апрель 29, 2022

The practice of agriculture has always been a source food production. increase in the global population leads to improvements agriculture, increasing crop quality and yield. Plant growth results from interaction between roots their environment, which is soil or planting medium that provides structural support as well water nutrients plant. Therefore, good management necessary prevent problems will directly affect plant health. Integrated pragmatic approach production, includes integrated pest focusing on protection. Currently, there an extended idea many microorganisms, such fungi bacteria, are useful since they attractive eco-friendly alternatives mineral fertilizers chemical pesticides. microbes interact with plants supply crops, control phytopathogens stimulate growth. These actions have beneficial implications agriculture. Despite great benefits microorganisms use quite limited; however, recent years. This may be because more progress needed field applications. One most employed genera Bacillus it several mechanisms act biofertilizers biopesticides. In this review, role special emphasis genus, health discussed, highlighting advances topic.

A review on mechanisms and prospects of endophytic bacteria in biocontrol of plant pathogenic fungi and their plant growth-promoting activities

Heliyon, Год журнала: 2024, Номер 10(11), С. e31573 - e31573

Опубликована: Май 23, 2024

Endophytic bacteria, living inside plants, are competent plant colonizers, capable of enhancing immune responses in plants and establishing a mutual relationship with them. bacteria have been described as being used to control phytopathogenic fungi while exhibiting growth-promoting activity. Here, we discussed the mechanisms actions discovered some major groups beneficial endophytic such Bacillus, Paenibacillus, Pseudomonas. Most studied strains these genera were isolated from rhizosphere soils, more extensive study is needed. It essential understand underlying biocontrol develop an effective screening approach for selecting potential bacteria. We suggested strategy based on mechanistic phenomena. This review will help screen sustainable agriculture.

Lysinibacillus spp.: an IAA-producing endospore forming-bacteria that promotes plant growth

Antonie van Leeuwenhoek, Год журнала: 2023, Номер 116(7), С. 615 - 630

Опубликована: Май 3, 2023

Lysinibacillus is a bacterial genus that has generated recent interest for its biotechnological potential in agriculture. Strains belonging to this group are recognized their mosquitocidal and bioremediation activity. However, years some reports indicate importance as plant growth promoting rhizobacteria (PGPR). This research sought provide evidence of the PGP activity spp. role indole-3-acetic acid (IAA) production associated with Twelve strains were evaluated under greenhouse conditions, six which increased biomass root architecture corn plants. In most cases, stimulation was evident at 108 CFU/mL inoculum concentration. All produced IAA high variation between them (20-70 µg/mL). The bioinformatic identification predicted genes allowed detection indole pyruvic pathway synthesize all strains; additionally, tryptamine detected two strains. Extracellular filtrates from strain's cultures coleoptile length an IAA-similar concentration pattern, demonstrates had auxin-like effect on tissue. Five previously showed PGPR also promoted Arabidopsis thaliana (col 0). These induced changes mutant plants (aux1-7/axr4-2), partial reversion phenotype indicated growth. work provided solid association activity, constitutes new approach genus. elements contribute exploration agricultural biotechnology.

PeerJ, Год журнала: 2023, Номер 11, С. e15128 - e15128

Опубликована: Май 10, 2023

Zinc-solubilizing rhizobacteria can convert insoluble zinc to an accessible form and increase Zn bioavailability in soil, which help mitigate deficiency crops. In this work, 121 bacterial isolates were isolated from the rhizosphere soils of peanuts, sweet potatoes, cassava, their capability solubilize was evaluated using Bunt Rovira’s agar containing 0.1% ZnO ZnCO 3 . Among these isolates, six showed high solubilization efficiencies ranging 1.32 2.84 1.93 2.27 on medium supplemented with , respectively. a quantitative analysis soluble liquid ZnO, isolate KAH109 maximum concentration 62.89 mg L −1 also produced most indole-3-acetic acid (IAA) at 33.44 whereas KEX505 IAA 17.24 along showing potassium activity. These strains identified as Priestia megaterium aryabhattai based 16S rDNA sequence analysis. greenhouse experiment conducted Nakhon Pathom, Thailand ability P. stimulate growth production green soybeans examined. The results revealed that inoculation considerably increased plant dry weight by 26.96% 8.79%, respectively, number grains per 48.97% 35.29% when compared those uninoculated control. According results, both be considered potential solubilizing bioinoculant promote yield soybeans.
