Agriculture in the 21st century is facing multiple challenges, such as those related to soil fertility, climatic fluctuations, environmental degradation, urbanization, and increase food demand for increasing world population. In meanwhile, scientific community key challenges crop production from existing land base. this regard, traditional farming has witnessed enhanced per acre yields due irregular injudicious use of agrochemicals, including pesticides synthetic fertilizers, but at a substantial cost. Another major concern modern agriculture that pests are developing pesticide resistance. Therefore, future sustainable requires alternative strategies can enhance an environmentally sound manner. The application rhizobacteria, specifically, plant growth-promoting rhizobacteria (PGPR), chemical gained much attention community. These harbor number mechanisms through which they promote growth, control pests, induce resistance various abiotic stresses. This review presents comprehensive overview involved growth promotion, biocontrol bioremediation contaminated soils. It also focuses on effects PGPR inoculation survival under stress. Furthermore, pros cons rhizobacterial along with directions discussed depth.

Metals to combat antimicrobial resistance

Nature Reviews Chemistry, Год журнала: 2023, Номер 7(3), С. 202 - 224

Опубликована: Фев. 8, 2023

Bacteria, similar to most organisms, have a love–hate relationship with metals: specific metal may be essential for survival yet toxic in certain forms and concentrations. Metal ions long history of antimicrobial activity received increasing attention recent years owing the rise resistance. The search antibacterial agents now encompasses ions, nanoparticles complexes (‘metalloantibiotics’). Although advanced clinic, metalloantibiotics are vast underexplored group compounds that could lead much-needed new class antibiotics. This Review summarizes developments this growing field, focusing on advances development metalloantibiotics, particular, those which mechanism action has been investigated. We also provide an overview alternative uses combat bacterial infections, including photodynamic therapy radionuclide diagnosis infections. Metals their promising source Their 3D geometry potential multiple mechanisms important assets; however, substantial investment research is needed advance them clinic.

The rhizosphere is undoubtedly the most complex microhabitat, comprised of an integrated network plant roots, soil, and a diverse consortium bacteria, fungi, eukaryotes, archaea. conditions have direct impact on crop growth yield. Nutrient-rich environments stimulate yield vice versa. Extensive cultivation exhaust soils which need to be nurtured before or during next crop. Chemical fertilizers are major source nutrients but their uncontrolled widespread usage has posed serious threat sustainability agriculture stability ecosystem. These chemicals accumulated in drained water, emitted air where they persist for decades causing overall Plant growth-promoting rhizobacteria (PGPR) present convert many plant-unavailable essential e.g., nitrogen, phosphorous, zinc, etc. into available forms. PGPR produces certain hormones (such as auxin, cytokinin, gibberellin), cell lytic enzymes (chitinase, protease, hydrolases, etc.), secondary metabolites, antibiotics, stress alleviating compounds (e.g., 1-Aminocyclopropane-1- carboxylate deaminase), chelating agents (siderophores), some signaling N-Acyl homoserine lactones) interact with beneficial pathogenic counterparts rhizosphere. multifarious activities improve soil structure, health, fertility, functioning directly indirectly support under normal stressed environments.

Integrating Biochar, Bacteria, and Plants for Sustainable Remediation of Soils Contaminated with Organic Pollutants

Environmental Science & Technology, Год журнала: 2022, Номер 56(23), С. 16546 - 16566

Опубликована: Окт. 27, 2022

The contamination of soil with organic pollutants has been accelerated by agricultural and industrial development poses a major threat to global ecosystems human health. Various chemical physical techniques have developed remediate soils contaminated pollutants, but challenges related cost, efficacy, toxic byproducts often limit their sustainability. Fortunately, phytoremediation, achieved through the use plants associated microbiomes, shown great promise for tackling environmental pollution; this technology tested both in laboratory field. Plant-microbe interactions further promote efficacy plant growth-promoting bacteria (PGPB) used assist remediation pollutants. However, efficiency microbe-assisted phytoremediation can be impeded (i) high concentrations secondary toxins, (ii) absence suitable sink these (iii) nutrient limitations, (iv) lack continued release microbial inocula, (v) shelter or porous habitats planktonic organisms. In regard, biochar affords unparalleled positive attributes that make it bacterial carrier health enhancer. We propose several barriers overcome integrating plants, PGPB, soil. Here, we explore mechanisms which PGPB soils, thereby improve analyze cost-effectiveness, feasibility, life cycle, practicality integration sustainable restoration management
