Table of contents

This volume is written with the objective of covering the basic issues in biological nitrogen fixation such as: the physiology, biochemistry and molecular genetics of nitrogen fixation; and the role of signal molecules and host gene expression in nodulation and nitrogen fixation. The book also details recent developments in biofertilizer technology, such as: the immobilization of cyanobacteria; endophytic nitrogen fixation; and solubilization and mobilization of nutrients by phosphobacteria and VA mycorrhiza and their role as bioinoculants.

This book provides a comprehensive overview of the benefits of biofertilizers as an alternative to chemical fertilizers and pesticides. Agricultural production has increased massively over the last century due to increased use of chemical fertilizers and pesticides, but these gains have come at a price. The chemicals are not only expensive; they also reduce microbial activity in agricultural soils and accumulate in the food chain, with potentially harmful effects for humans. Accordingly, it is high time to explore alternatives and to find solutions to overcome our increasing dependence on these chemicals. Biofertilizers, which consist of plant remains, organic matter and microorganisms, might offer an alternative. They are natural, organic, biodegradable, eco-friendly and cost-effective. Further, the microbes present in the biofertilizers are important, because they produce nutrients required for plant growth (e.g., nitrogen, phosphorus, potassium), as well as substances essential for plant growth and development (e.g., auxins and cytokinins). Biofertilizers also improve the physical properties, fertility and productivity of soil, reducing the need for chemical fertilizers while maintaining high crop yield. This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment. The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. As such, it offers a valuable resource for researchers, academics and students in the broad fields of microbiology and agriculture.

The rapid increase in microbial resources along with the development of biotechnological methods has revolutionized the field of microbial biotechnology. Genome characterization methods and metagenomic approaches further illustrate the role of microorganisms in various fields of research. Recent Advancement in Microbial Biotechnology: Agricultural and Industrial Approach provides an overview on the recent application of the microorganisms in agricultural and industrial improvements. The purpose of this book is to integrate all these diverse areas of research in a common platform. Recent advancement in Microbial Biotechnology targets researchers from both academia and industry, professors and graduate students working in molecular biology, microbiology and biotechnology. - Gives insight in the exploration of microbial functional diversity in different systems - Highlights important microbes and their role in enhancing agricultural productivity - Provides understanding to the basics with advance information of microbial biotechnology - Explores the importance of microbial genomes studies in agricultural and industrial applications

Sharply focused, up-to-date information on microbial biofertilizers—including emerging options such as Piriformospora indica and Matsutake The Handbook of Microbial Biofertilizers provides in-depth coverage of all major microbial biofertilizers (rhizobia, arbuscular mycorrhizal fungi, and cyanobacteriaas well as new and emerging growth promoters (endophytes). It examines the role of microbes in growth promotion, bioprotectors, and bioremidiators, and presents protocols and practical strategies for using microbes in sustainable agriculture. An abundance of helpful charts, tables, and figures make complex information easy to access and understand. In this first-of-its-kind volume, contributors from 11 countries and several continents address important issues surrounding microbial biofertilizers, including: the rhizobium-host-arbuscular mycorrhizal tripartite relationship mycorrhiza as a disease suppresser and stress reducer mycorrhiza helping bacteria the impact of functional groups of soil microorganisms on nutrient turnover PBPRs as biofertilizers and biopesticides the potential of wild-legume rhizobia for use as a biofertilizers the expanding role of blue-green algae in sustainable agriculture the role of microbial fertilizers in sustainable plant production new and emerging endophytes the commercial potential of biofertilizers In this young century, the use of biofertilizers is already growing rapidly. It has been recognized that these environment-friendly bioprotectors, growth boosters, and remediators are essential for soil/plant health. The Handbook of Microbial Biofertilizers is designed to fit the expanding information needs of current and future biotechnologists, microbiologists, botanists, agronomists, environmentalists, and others whose work involves sustained agriculture.

Great attention has been paid to reduce the use of conventional chemical fertilizers harming living beings through food chain supplements from the soil environment. Therefore, it is necessary to develop alternative sustainable fertilizers to enhance soil sustainability and agriculture productivity. Biofertilizers are the substance that contains microorganisms (bacteria, algae, and fungi) living or latent cells that can enrich the soil quality with nitrogen, phosphorous, potassium, organic matter, etc. They are a cost-effective, biodegradable, and renewable source of plant nutrients/supplements to improve the soil-health properties. Biofertilizers emerge as an attractive alternative to chemical fertilizers, and as a promising cost-effective technology for eco-friendly agriculture and a sustainable environment that holds microorganisms which enhance the soil nutrients' solubility leading a raise in its fertility, stimulates crop growth and healthy food safety. This book provides in-depth knowledge about history and fundamentals to advances biofertilizers, including latest reviews, challenges, and future perspectives. It covers fabrication approaches, and various types of biofertilizers and their applications in agriculture, environment, forestry and industrial sectors. Also, organic farming, quality control, quality assurance, food safety and case-studies of biofertilizers are briefly discussed. Biofertilizers' physical properties, affecting factors, impact, and industry profiles in the market are well addressed. This book is an essential guide for farmers, agrochemists, environmental engineers, scientists, students, and faculty who would like to understand the science behind the sustainable fertilizers, soil chemistry and agroecology.
