Further, microbe – microbe interactions allow the simulation microbial community interactions naturally, and is one of the many modern methods for the development of novel and effective metabolites.

This contributed volume explores how plant growth-promoting rhizobacterias (PGPR) provide a wide range of benefits to the plant. Further, it discusses the key roles PGPR play in nutrient acquisition and assimilation, improved soil texture, secreting, and modulating extracellular molecules. The book outlines how plant secondary metabolites are natural sources of biologically active compounds used in a wide range of applications, and surveys the significant role of volatile organic compounds (VOCs) in plant communication by mediating above- and below-ground interactions between plants and the surrounding organisms. This volume compiles research from leading scientists from across the globe, linking the translation of basic knowledge to innovative applied research. The book focuses on the following three categories: 1) understanding the secondary metabolites produced by PGPR, the signaling mechanisms and how they affect plant growth, 2) the plausible role of volatile organic compounds produced by PGPR, their role and the signaling mechanism for plant growth promotion, and 3) Applications of VOCs and secondary metabolites of PGPR for seed germination, plant growth promotion; stress tolerance and in-plant health and immunity.

Attaining sustainable agricultural production while preserving environmental quality, agro-ecosystem functions and biodiversity represents a major challenge for current agricultural practices; further, the traditional use of chemical inputs (fertilizers, pesticides, nutrients etc.) poses serious threats to crop productivity, soil fertility and the nutritional value of farm produce. Given these risks, managing pests and diseases, maintaining agro-ecosystem health, and avoiding health issues for humans and animals have now become key priorities. The use of PGPR as biofertilizers, plant growth promoters, biopesticides, and soil and plant health managers has attracted considerable attention among researchers, agriculturists, farmers, policymakers and consumers alike. Using PGPR as bioinoculants can help meet the expected demand for global agricultural productivity to feed the world's booming population, which is predicted to reach roughly 9 billion by 2050. However, to provide effective bioinoculants, PGPR strains must be safe for the environment, offer considerable plant growth promotion and biocontrol potential, be compatible with useful soil rhizobacteria, and be able to withstand various biotic and abiotic stresses. Accordingly, the book also highlights the need for better strains of PGPR to complement increasing agro-productivity.

Sustainable increase in agricultural production while keeping the environmental quality, agro-ecosystem function and biodiversity is a real challenge in current agricultural practices. Application of PGPR can help in meeting the expected demand for increasing agricultural productivity to feed the world's booming population. Global concern over the demerits of chemicals in agriculture has diverted the attention of researchers towards sustainable agriculture by utilizing the potential of Plant Growth Promoting Rhizobacteria (PGPR).

This edited book aims to focus on microbial diversity in arid lands and deserts versus specific microbial assemblages associated with plants. The book explains ecological drivers that shape this diversity, how plant-associated microbiomes are selected, and their biotechnological potential are discussed. Diversity and functional redundancy of these associated PGPM make them very active in supporting plant improvement, health and resistance to drought, salt and other stresses, and these dimensions will be explored in this book. Implementing proper biotechnological applications of the arid and desert-adapted PGPM constitutes a sizeable challenge, and the book attempts to take up that challenge and help researchers in this field to gain a detailed understanding of PGPM from arid ecosystems. This book serves as a handbook for research workers, teachers, postgraduate students and extension personnel, other development workers, and policy planners engaged in arid zone development.

The book highlights the importance of prebiotics, probiotics and synbiotics in the signalling mechanism between gut microbiota and brain, also referred to as the gut-brain axis. A stable gut microbiota is essential for normal gut physiology and overall health, since it assists in proper signalling along the brain-gut axis. The book describes how the cross talks between gut microbiota and brain, not only regulate gastro-intestinal functions but also ensure proper functioning of cognitive behaviour and immunological functions. The various chapters describe probiotic microorganisms that colonize gastrointestinal tract and provide an array of health benefits to the host. It further elaborates about certain non-digestible oligosaccharides (prebiotics) are easily fermented by specialist microbes in the gut, to produce health-promoting metabolites and inhibit the growth of pathogenic bacteria. This book is useful for students, researchers and scientists in the field of microbiology, food science and nutrition. It is also meant for industry experts involved in developing nutraceuticals.

Increasing agro productivity to feed a growing global population under the present climate scenario requires optimizing the use of resources and adopting sustainable agricultural production. This can be achieved by using plant beneficial bacteria, i.e., those bacteria that enhance plant growth under abiotic stress conditions, and more specifically, microorganisms such as plant growth promoting rhizobacteria (PGPR), which are the most promising candidates in this regard.

Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture focuses on plant health in agro-ecosystems of various economically important cash and food crops with a concern to promote sustainable agriculture. They have emerged as a key organic tool for enhancing yields. In a natural environment the interactions between plants and phytopathogenic fungi are complex and survival requires a development of resistance to plant diseases. Diversity of Plant Growth Promoting Rhizobacteria (PGPR) diversity depends on the nature of root exudates and soil conditions that affect their interaction with host plants. Novel strategies, such as, applying bioactive natural products against the pathogenic fungus are required to control disease sustainably. Various classes of secondary metabolites including lipopeptides, macrolides, alkaloids, terpenoids and phenolics from microorganisms and plants strongly suppress fungal growth and can also be effective in controlling plant diseases both in vitro and in vivo. The modes of actions of some potential antifungal secondary metabolites against pathogenic fungus are also discussed. Eco-friendly fungal species and their metabolites are excellent agents used for regulating various fungal and bacterial phytopathogens and may have tremendous potential for other applications, and play a key role in enhancing plant tolerance to stress. Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture also covers bovine-based formulations used for sustainable production and nutritional security through horticultural crops, thereby addressing the problems associated with malnutrition and under-nutrition encountered by small and marginal farmers, as well as by families facing resource constraints. These techniques can also improve breathable air, drinkable water, and consumable foods. This book addresses the need to mitigate the health problems of people via organic crop production and to improve the socio-economic status of farmers (especially in developing countries), and to revitalize agricultural sustainability.
