PREFACE
The term ecology is derived from the Greek words oikos house and logos study . Microbial ecology is the study of microbes in the environment and their interactions with each other. Microbial ecology deals only with a segment of the total ecological system. Microbial ecology is the relationship of microorganisms with one another and with their environment. It concerns the three major domains of life - Eukaryota, Archaea, and Bacteria - as well as viruses. Microorganisms, by their omnipresence, affect the entire biosphere. They are present in virtually all of our planet's environments, including some of the extreme habitat, from acidic lakes to the deepest ocean, and from frozen environments to hydrothermal vents. Microbial life is amazingly diverse and microorganisms literally cover the planet. An average gram of soil contains approximately one billion 1,000,000,000 microbes representing probably several thousand species. Microorganisms have special impact on overall biosphere. They are the backbone of ecosystems of the zones where light cannot approach. In such zones, chemosynthetic bacteria are present which provide energy and carbon to the other organisms there. Some microbes are decomposers, which have ability to recycle the nutrients. Microbes have a special role in biogeochemical cycles. Microbes, especially bacteria, are of great importance because their symbiotic relationship either positive or negative has special effects on the ecosystem. The study of Microbial Ecology includes 1 Microbial population and community ecology, 2 Theoretical and mathematical advances in microbial ecology, 3 Microbial drivers of biogeochemical processes, 4 Inter- and intraspecific microbial communication, 5 Tropic interactions with animals and plants, 6 Spanning the spectrum from mutualisms to parasitism and pathogenicity strategies of microbial adaptation, 7 Microbial processes and interactions in extreme or unusual environments and environmental pollution, Functional approaches to studying host-microbe interactions and communication, and 8 Novel molecular and genomics approaches, etc. The present book has been designed to incorporate all aspects of Microbial ecology. The chapters includes, Microbial Ecology Introduction, Components of Microbial Ecology, Microbial Diversity, Microbial Taxonomy, Ecosystem and Microbial Communities, Microbes in Air, Microbes in Water, Microbes in Soil, Biogeochemical Cycles Carbon Cycle, Nitrogen Cycle, Phosphorus Cycle, Sulphur Cycle, Microbial Population Interaction or Ecological Interrelationships, Adaptation of Microorganisms to Environmental Conditions, The Rumen Microbial Ecosystem, Microbes Biomass Wastes and Energy Production, Biological Solid Agricultural Waste Management, Microbe Sewage and Water Treatment, Bioremidation,
Biodegradation of Xenobiotics, Biomining, Microbial Control of Disease Causing Pest and Pathogen, Ecological Aspects of Biodeterioration, Biomining. In the end, Practical on Microbial Ecology have been appended. We trust, the book will meet the requirement of under and post graduate students of basic and agricultural sciences. We are thankful Dr. Updesh Purohit, Managing Director, Agrobios India for continuous cooperation and publishing the book in record time.
