Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils.

The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on...

Metal contamination is an increasing ecological and eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils are key features for soil bioremediation.

Following an introduction to the physical, chemical and biological components of contaminated soils, various chapters address the interactions of soil, microorganisms, plants and the water phase necessary to transfer metals into biological systems. These include topics such as potential hazards at mining sites; rare earth elements in biotic and abiotic acidic systems;...

Plant-based medicines play an important role in all cultures, and have been indispensable in maintaining health and combating diseases. The identification of active principles and their molecular targets from traditional medicine provides an enormous opportunity for drug development. Using modern biotechnology, plants with specific chemical compositions can be mass propagated and genetically improved for the extraction of bulk active pharmaceuticals. Although there has been significant progress in the use of biotechnology, using tissue cultures and genetic transformation to investigate and...

Sebacinales have emerged as a fascinating order with mutualistic plant-fungal symbionts that consists of exclusively beneficial fungi.

This volume of Soil Biology presents an overview of the current results in Sebacinales research with a focus on the potential of these fungi in crop improvement and stress tolerance. The authors demonstrate that Sebacinales are not only extremely versatile in their associations with roots, but are also almost universally present as symptomless endophytes. With this extraordinary diversity, Sebacinales with the key fungus Piriformospora indica...

Biological remediation methods have been successfully used to treat polluted soils. While bacteria have produced good results in bioremediation for quite some time now, the use of fungi to decontaminate soils has only recently been established.

This volume of Soil Biology discusses the potentials of filamentous fungi in bioremediation. Fungi suitable for degradation, as well as genetically modified organisms, their biochemistry, enzymology, and practical applications are described. Chapters include topics such as pesticide removal, fungal wood decay processes, remediation of soils...

Symbiotic Fungi - Principles and Practice presents current protocols for the study of symbiotic fungi and their interactions with plant roots, such as techniques for analyzing nutrient transfer, ecological restoration, microbial communication, and mycorrhizal bioassays, AM inoculum procedures and mushroom technology.

The protocols offer practical solutions for researchers and students involved in the study of symbiotic microorganisms. The volume will be of great use for basic research, biotechnological applications, and the development of commercial products.

Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume.

The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects...
