Abstract The burgeoning global market for soil microbial inoculants use in agriculture is being driven by pressure to increase sustainable crop production managing pests and diseases without environmental impacts. Microbial inoculants, based predominantly on bacteria fungi, are applied as alternatives conventional inorganic fertilizers (biofertilizers) or carry out specific functions including biocontrol of (biopesticides), bioremediation enhancement characteristics. While some such rhizobia have a long successful history use, others performed inconsistently the field failed live up their promise suggested laboratory testing. A more precise understanding ecology modes action inoculant strains key optimizing efficacy guiding targeted situations where they address limitations production. This will require greater collaboration between science disciplines, microbiology, plant science, molecular biology agronomy. Inoculants must be produced formulated ensure effective establishment practicality implementation alongside existing cropping practices. New approaches strain selection construction beneficial consortia should lead efficacious products. Extensive rigorous evaluation under range conditions has rarely been undertaken urgently needed validate emerging products underpin growers, especially that largely unregulated at present.

Abstract The global amount of solid waste has dramatically increased as a result rapid population growth, accelerated urbanization, agricultural demand, and industrial development. world's is expected to reach 8.5 billion by 2030, while production will 2.59 tons. This deteriorate the already strained environment climate situation. Consequently, there an urgent need for methods recycle waste. Here, we review recent technologies treat waste, assess economic feasibility transforming into energy. We focus on municipal, agricultural, found that methane captured from landfilled-municipal in Delhi could supply 8–18 million houses with electricity generate 7140 gigawatt-hour, prospected potential 31,346 77,748 gigawatt-hour 2030 2060, respectively.

Abstract Background Understanding the genetic and environmental factors that structure plant microbiomes is necessary for leveraging these interactions to address critical needs in agriculture, conservation, sustainability. Legumes, which form root nodule symbioses with nitrogen-fixing rhizobia, have served as model plants understanding genetics evolution of beneficial plant-microbe decades, thus added value models plant-microbiome interactions. Here we use a common garden experiment 16S rRNA gene amplicon shotgun metagenomic sequencing study drivers microbiome diversity composition three genotypes legume Medicago truncatula grown two native soil communities. Results Bacterial decreased between external (rhizosphere) internal compartments (root endosphere, leaf endosphere). Community was shaped by strong compartment × origin genotype interactions, driven significant effects rhizosphere endosphere. Nevertheless, all were dominated Ensifer , genus rhizobia forms symbiosis M. additional suggests nodulating not genetically distinguishable from those elsewhere plant.

The recent literature indicates that plant growth-promoting bacteria (PGPB) employ a range of mechanisms to augment plant's ability ameliorate salt and drought stress. These include synthesis auxins, especially indoleacetic acid, which directly promotes growth; antioxidant enzymes such as catalase, superoxide dismutase peroxidase, prevents the deleterious effects reactive oxygen species; small molecule osmolytes, e.g., trehalose proline, structures water content within bacterial cells reduces turgor pressure; nitrogen fixation, improves exopolysaccharides, protects from loss stabilizes soil aggregates; antibiotics, stress-debilitated plants pathogens; enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, lowers level ACC ethylene in plants, thereby decreasing stress-induced senescence. Many reports overcoming these stresses indicate most successful PGPB possess several mechanisms; however, involvement any particular mechanism protection is nearly always inferred not proven.

Microbial consortium inoculation has been proposed as a natural-based strategy to safeguard multiple ecosystem services. Still, its observed effects and comparisons single-species have yet be systematically quantified. In this global meta-analysis of 51 live-soil studies (carefully selected from pool 2149 studies), we compared the impact (mean variability) inoculations on biofertilization bioremediation. Our results showed that both increased plant growth by 29 % 48 %, respectively, pollution remediation 80 with non-inoculated treatments. We revealed diversity inoculants synergistic effect between frequently used inoculums (e.g., Bacillus Pseudomonas) contributed effectiveness inoculation. Despite reduction in efficacy field settings greenhouse results, had more significant overall advantage under various conditions. recommend increasing original soil organic matter, available N, P content regulating pH 6–7 achieve better effect. Overall, these findings support use microbial consortia for improved bioremediation living suggest perspectives constructing inoculating beneficial consortia.

Inoculation of soil with living microbes or propagules has grown in interest and application due to the modification/degradation systems (including native microbial communities), need maintain agricultural yields fewer synthetic inputs. Whilst beneficial microorganisms such as plant growth promoting bacteria (PGPB) mycorrhizal fungi have been employed via inoculation, their utilisation an agronomic tool remains trivial context large-scale commercial agriculture. The development inoculation products thus far largely focused on capacity support health (and correlating yield/profitability), little attention paid ability these organisms/products influence carbon. Given expected inoculant industry (estimated reach US$12.5b revenue by 2027), increasing commercialisation carbon sequestration (via credits other financially linked instruments), find viable solutions assist drawdown atmospheric CO2, a greater understanding role cycling is required order facilitate capable supporting retention Here, we review mechanisms which contribute suggest several groups that may be promising candidates for further exploration. Of many mediated identified, highlight (among others) arbuscular transition from labile recalcitrant pools (mineral associated aggregated), melanising endophytic potential source stable carbon, PGPB stimulators growth/reliance entering pool. We put forward ‘biochar + microbe system’ avenue overcome current limitations building retaining stocks. This timely, given challenges facing global food production, address climate change.

Sustainable food production, among other non-intensive production systems, involves the important interactions of myriads plant growth-promoting microorganisms, plant, soil, soil fauna, and utilizable carbon in rhizosphere capable enhancing health, growth, protection that lead to increased crop productivity. Plant rhizobacteria (PGPR) including symbiotic rhizobia free-living possess traits help enhance growth due their many modes action start with ability colonize both intracellular extracellular niche search for a source reduction free use quantity agrochemicals. In past few decades, focus on developing biosafety agro-products has shifted from agrochemical-based applications more sustainable system without posing negative impacts microflora or fauna. The present review focuses application PGPR inoculants soils seeds improve biological nitrogen fixation, solubilization phosphate, secretion phytohormones required especially pressured environment. We discuss how enhances nutritional regulation hormonal balance plants, bacterial taxa enrichment, improvement sources utilization beneficial growth. highlight antagonistic synergistic microorganisms within beyond bulk which indirectly boosts rate induces resistance against phytopathogens. While soil-borne pathogens continually oppose functions these improved diverse strategies form agro-compatibility, root colonization, nutrient, iron, space competition, systemic resistance, antibiotics synthesis, lytic acid, hydrogen cyanide, siderophore advanced production. Finally, we highlighted roles phytoremediation, techniques applying microbial commercialization products challenges countries have defeat.
