Exploring Microbial Potential for Sustainable Agriculture

Microsphere

Microbes play diverse roles in agriculture. They are present in soil, in or on plant parts, and are also found associated with livestock. Soil microbes regulate biogeochemical cycles and cycling of organic matter and nutrients. They secrete compounds that promote growth of the plants by direct or indirect pathways. Many microbes possess catabolic genes that can degrade pesticides. Microbes also work against phytopathogens by inducing resistance in plants, hyperparasitism, antibiosis, competing for nutrients or space, or by producing secondary metabolites. Microbial balance in the gut of the ruminants influences their health and thus their productivity. More recently, in order to improve agricultural production, role of microbes has been explored for developing agricultural practices like organic farming and Climate Smart Agriculture. An understanding of these diverse roles of microbes can aid in the development of microbial interventions for sustainable agriculture, such as developm...

Microbial Contribution to Agricultural Development and Environmental Conservation

American journal of biomedical science & research, 2023

Alternatives are required to solve challenges encountered in the food security sector with the increasing global population due to ecological instability and changes observed in climate. Abiotic stress including high salinity and drought caused the degradation of soil thereby making it not fittable for agricultural practices to reveal the problem encountered. However, microbial communities including bacteria, fungi, and archaea have been proven to contribute to soil health, plant growth promotion, induce systemic resistance against diseases, and overall promote abundant production of agricultural products. These microbes also have the potential to control biotic and abiotic stresses and they are associated with improving climate-resilient soils. This review reveals the green and sustainable methods employed to combat soils encountering the problem posed by the change in climate and further reveals the potential of the microbes to stimulate the production of nutrients or elements required for agricultural sustainability, and also the beneficial value they add to the environment via biogeochemical cycle.

Microbiome as a Key Player in Sustainable Agriculture and Human Health

Frontiers in Soil Science

The aggregate of microorganisms in the soil environment is a microbiome that emerged as a vital component of sustainable agriculture in the recent past. These beneficial microorganisms perform multiple plant growth-promoting activities including fixation, mineralization, solubilization, and mobilization of nutrients, production of siderophores, antagonistic substances, antibiotics, and release of plant growth-promoting substances, such as auxin and gibberellin hormones, mediated by interactions between host plant roots and microbes in the rhizosphere. Numerous plant species forms symbiotic association with microbes and draw the benefit of mineral nutrient supply with the expense of minimal energy, and their distribution is governed by nature and the number of root exudates, crop species, and cultivars. On the other hand, microorganisms with critical roles in the microbiome can be isolated, formulated, and developed as a new biological product called biofertilizers. Agriculturally, i...

Linking Soil Microbial Diversity to Modern Agriculture Practices: A Review

International Journal of Environmental Research and Public Health

Agriculture is a multifarious interface between plants and associated microorganisms. In contemporary agriculture, emphasis is being given to environmentally friendly approaches, particularly in developing countries, to enhance sustainability of the system with the least negative effects on produce quality and quantity. Modern agricultural practices such as extensive tillage, the use of harmful agrochemicals, mono-cropping, etc. have been found to influence soil microbial community structure and soil sustainability. On the other hand, the question of feeding the ever-growing global population while ensuring system sustainability largely remains unanswered. Agriculturally important microorganisms are envisaged to play important roles in various measures to raise a healthy and remunerative crop, including integrated nutrient management, as well as disease and pest management to cut down agrochemicals without compromising the agricultural production. These beneficial microorganisms see...

Trends of Microbial Biotechnology for Sustainable Agriculture and Biomedicine Systems: Diversity and Functional Perspectives describes how specific techniques can be used to generalize the metabolism of bacteria that optimize biologic improvement strategies and bio-transport processes. Microbial biotechnology focuses on microbes of agricultural, environmental, industrial, and clinical significance. This volume discusses several methods based on molecular genetics, systems, and biology of synthetic, genomic, proteomic, and metagenomics. Recent developments in our understanding of the role of microbes in sustainable agriculture and biotechnology have created a highly potential research area. The soil and plant microbiomes have a significant role in plant growth promotion, crop yield, soil health and fertility for sustainable developments. The microbes provide nutrients and stimulate plant growth through different mechanisms, including solubilization of phosphorus, potassium, and zinc; biological nitrogen fixation; production of siderophore, ammonia, HCN and other secondary metabolites which are antagonistic against pathogenic microbes. This new book provides an indispensable reference source for engineers/bioengineers, biochemists, biotechnologists, microbiologists, agrochemists, and researchers who want to know about the unique properties of this microbe and explore its sustainable agriculture future applications

Improvement of Soil Microbial Diversity through Sustainable Agricultural Practices and Its Evaluation by -Omics Approaches: A Perspective for the Environment, Food Quality and Human Safety

Soil is one of the key elements for supporting life on Earth. It delivers multiple ecosystem services, which are provided by soil processes and functions performed by soil biodiversity. In particular, soil microbiome is one of the fundamental components in the sustainment of plant biomass production and plant health. Both targeted and untargeted management of soil microbial communities appear to be promising in the sustainable improvement of food crop yield, its nutritional quality and safety. –Omics approaches, which allow the assessment of microbial phylogenetic diversity and functional information, have increasingly been used in recent years to study changes in soil microbial diversity caused by agronomic practices and environmental factors. The application of these high-throughput technologies to the study of soil microbial diversity, plant health and the quality of derived raw materials will help strengthen the link between soil well-being, food quality, food safety and human h...

The potential for plant growth-promoting bacteria to impact crop productivity in future agricultural systems is linked to understanding the principles of microbial ecology

Frontiers in Microbiology

Global climate change poses challenges to land use worldwide, and we need to reconsider agricultural practices. While it is generally accepted that biodiversity can be used as a biomarker for healthy agroecosystems, we must specify what specifically composes a healthy microbiome. Therefore, understanding how holobionts function in native, harsh, and wild habitats and how rhizobacteria mediate plant and ecosystem biodiversity in the systems enables us to identify key factors for plant fitness. A systems approach to engineering microbial communities by connecting host phenotype adaptive traits would help us understand the increased fitness of holobionts supported by genetic diversity. Identification of genetic loci controlling the interaction of beneficial microbiomes will allow the integration of genomic design into crop breeding programs. Bacteria beneficial to plants have traditionally been conceived as “promoting and regulating plant growth”. The future perspective for agroecosyst...

Microbiomes for Agro-environmental Sustainability

Microbial Ecology, 2021

The beneficial microbes play an important role in medical, industrial, and agricultural processes. The precious microbes belong to different groups including archaea, bacteria, and fungi which can be sort out from different habitat such as extreme environments (acidic, alkaline, drought, pressure, salinity, and temperatures) and associated with plants (epiphytic, endophytic, and rhizospheric) and human. The beneficial microbes exhibited multifunctional plant growth promoting (PGP) attributes such as N2-fixation, solubilization of micronutrients (phosphorus, potassium and zinc), and production of siderophores, antagonistic substances, antibiotic, auxin, and gibberellins. These microbes could be applied as biofertilizers for native as well as crops growing at diverse extreme habitat. Microbes with PGP attributes of N2-fixation, P-, and K-solubilization could be used at a place of NPK chemical fertilizers. Agriculturally, important microbes with Fe-and Zn-solubilizing attributes can be used for biofortification of micronutrients in different cereal crops. The biofertilizers are an eco-friendly technology and bioresources for sustainable agriculture and human health. In general, the concentrations of micronutrient in different crops are not adequate for human nutrition in diets. Hence, consumption of such cereal-based diet may result in micronutrient malnutrition and related severe health complications. The biofortification approach is getting much attention to increase the availability of micronutrients, especially Fe and Zn in the major food crops. The beneficial microbes can be used as probiotic as functional foods for human health. Probiotics microbes such as Bifidobacterium, Lactobacillus, Methanobrevibacter, Methanosphaera, and Saccharomyces are increasingly being used as dietary supplements in functional food products. The microbes with beneficial properties could be utilized for sustainable agriculture and human health.
