The present book provides a broad overview of mycology. It explores the diversity of keratinophilic, marine and those involved in bio-deterioration causing losses in paper industry, and discusses role of fungal biotechnology in pulp and paper industry. Considering the sustainability of environment, ectomycorrhiza and arbuscular mycorrhizal (AMF) fungi can be applied as biofertilizers in nurseries and plantations. Moreover, answers for questions of bioremediation with special regards to handling toxic metals in wastewater, recycling of agro-wastes, etc. has been incorporated. This book would be very useful for readers of diverse disciplines including mycologist, plant pathologists, mycotechnologist, botanists, zoologists, pharmacologists, environmentalists and medical mycologists. Salient Feathers: Includes current developments in mycodiversity and biotechnology; Targets the most important issues of biotechnology; Provides new trends and innovative ideas in mycotechnology; Deals with diverse topics-fungi from soil to sea, from disease to drug potential; Focuses on eco-friendly biotechnology, viz., biofertilizers, biocontrol agents and bioremediators; Contains suitable materials for students, teachers and researchers.
