Management of Mycorrhizal Symbiosis for Mycoremediation and Phytostabilization overviews the many advances that have been made in mycorrhizal research and practice. Many microorganisms are present in plant rhizosphere, among which root-associated mycorrhizal fungi are ancient fungi that have evolved along with the evolution of plants. Mycorrhizal fungi of the soil can colonize more than 80% of terrestrial plant roots, where the mycorrhizal symbiosis helps the host to obtain water and nutrients, in exchange of lipids and sugars from the host plant to the mycorrhizal fungus for its life history. The mycorrhizal extraradical mycelium can extend beyond the root zone, enabling the absorption of water and nutrients from the soil. Thus, the reciprocal symbiosis can provide an important technology for crop reduction of fertilizer inputs and environmental stewardship. Mycorrhizal fungal fertilizers have been produced commercially in Europe, Asia, and North America, which provides strong support for mycorrhizal applications in agriculture and environmental field. Therefore, there is a great need to summarize the recent research results and bring them together in a book. This book provides soil scientists and mycorrhizal researchers with a comprehensive overview of new advances in mycorrhizal fungi. It may also serve as a reference for professionals in adjacent fields working in environmental management, microbiology, and crop science.Provides readers with new insights into mycorrhizae, such as lipids as mycorrhizal energy substances, and diversity of mycorrhizal fungi in various environmentsPresents the role of mycorrhizal fungi in sustainable soil scienceHighlights the potential of phytoremediation and mycorrhizal remediation in contaminated soils

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.

This book reviews the potential mechanisms in arbuscular mycorrhizas (AMs), in the hope that this can help arbuscular mycorrhizal fungi (AMF) to be more used efficiently as a biostimulant to enhance stress tolerance in the host plants. AMF, as well as plants, are often exposed to all or many of the abiotic and biotic stresses, including extreme temperatures, pH, drought, water-logging, toxic metals and soil pathogens. Studies have indicated a quick response to these stresses involving several mechanisms, such as root morphological modification, reactive oxygen species change, osmotic adjustment, direct absorption of water by extraradical hyphae, up-regulated expression of relevant stressed genes, glomalin-related soil protein release, etc. The underlying complex, multi-dimensional strategy is involved in morphological, physiological, biochemical, and molecular processes. The AMF responses are often associated with homeostatic regulation of the internal and externalenvironment, and are therefore critical for plant health, survival and restoration in native ecosystems and good soil structure.
