This edited volume covers all aspects of microbes in consortia; their roles in the ecological balance of soil by mineralize soil nutrients, plant growth promotion, protecting plants from disease by acting as biocontrol agents etc. Step-by-step descriptions are provided to the development and designing strategies of microbial consortia of rhizobacteria, phytohormone producing with biocontrol; ACC-deaminase producing with siderophore producing; vice-versa, and many combinations of multifaceted bacteria. The development of microbial consortia into successful bioinoculant and biofertilizers is also included in various chapters. In addition, molecular mechanisms to study the synergistic behaviors of rhizobacteria, accompanied by numerous helpful schematic drawings. Using phylogeny to justify the molecular similarity among two different bacteria identifies the possibility of microbial synergism, fruitful to development of microbial consortium and establish them in the rhizosphere with consorted mechanisms. In addition, clear drawings are included in support of understanding the natural phenomenon of synergism in below-ground ecosystem. Essential information is provided on ecological management by consorted mechanisms of rhizobacteria that directly affect 'agriculture sustainability' and an individual chapter is devoted to the understanding of future research, and addressing bottlenecks and successful steps. This book assists the academicians, researchers and NGOs in negotiating the steep learning curve involved in gaining the skills needed to perform design and development of microbial consortiums, preparation of PGPR-based fertilizers, which offers significant advantages in terms of pertaining novel knowledge on the groundbreaking research, still ongoing.

This book covers aspects of biological nitrogen fixation along with the unique signaling and interaction between the diazotrophic bacteria and plants, especially the non-legumes. Nitrogen is the most important growth-limiting nutrient in the ecosystems and biological nitrogen fixation involving microbial symbionts, mainly rhizobia and legumes holds enormous interest across the globe. However, free-living rhizobacteria of non-legumes especially cereals, also establish themselves within the root system, fixing nitrogen and contributing to plant productivity, soil fertility, and agricultural sustainability. These non-symbiotic nitrogen fixers additionally exhibit various plant growth-promoting traits elevating productivity, fortifying nutrient content, and managing water stress in plants. The recent perspectives highlighting the mechanisms and background of non-symbiotic nitrogen fixation provide answers to unravel the potential of nitrogenase and various spectra of habitats of rhizobia and other diazotrophic bacteria. Further, the application of genetic engineering and the development of nitrogen-fixing cereals can provide a possible solution to the problem of food shortage. The book includes various scientific inputs providing comprehensive knowledge about the emergence of agricultural sustainability through nitrogen-fixing bacteria. The book illustrates the systematic mechanisms involved in biological nitrogen fixation through various illustrations, schematic drawings, and flow charts aiding in better understanding. The chapters elaborate on the physiology and metabolism of plant-bacteria interaction in different crops under diverse environmental conditions. Thus, the volume will provide a holistic scenario helping in advancing the novel plant-microbe interactions, cell-signaling, and plant-molecular interactions. The book will assist the agronomists, microbiologists, ecologists, plant pathologists, molecular biologists, environmentalists, policymakers, conservationists, and NGOs to develop biofertilizers and bioinoculants using various genera of microbes and contribute to the targets of sustainable goals in an eco-friendly manner.
