Handbook of Molecular Microbial Ecology

Microbes are significant drivers of the world’s ecosystems. Microbial ecology is the study of microbes in the environment and their interactions with each other. Microbes are the tiniest creatures on Earth, yet despite their small size, they have an enormous impact on us and on our environment. Microbial ecology can help answer some of our most practical questions such as “How can we improve our lives?” as well as basic questions such as “Why are we here?” Microbial ecology can show us our place in the cosmos -- how life originated and how it evolved, and how we are related to the great diversity of all other organisms. The study of microbial ecology can help us improve our lives through the use of microbes in environmental restoration, food production, and bioengineering of useful products such as antibiotics, food supplements, and chemicals. The study of these bizarre and diverse creatures that are everywhere yet nowhere to be seen is fascinating and a pursuit that appeals to the curiosity and playfulness in us. Most types of microbes remain unknown. It is estimated that we know less than 1% of the microbial species on Earth. Yet microbes surround us everywhere - air, water, soil. The vast majority of the world’s diversity and metabolic potential lies within micro-organisms, yet we are just beginning to understand and utilize this ultimate resource of biological diversity. Microbial populations are able to tolerate and to grow under varying environmental conditions, including habitats with extreme environmental conditions such as hot springs and salt lakes. Understanding the environmental factors controlling microbial growth and survival offers insight into the distribution of microorganisms in nature, and many studies in microbial ecology are concerned with examining the adaptive features that permit particular microbial species to function in particular habitats. The field of microbial ecology has been revolutionized in the past two decades by the introduction of molecular methods into the toolbox of the microbial ecologist.

Handbook of Molecular Microbial Ecology starts by looking at general Microbial ecology in Chapter 1 and then introduces some strategies for genome analysis on Chapters 2 and 3. On Chapter 4, the new concept of species in the metagenomics era is discussed. It continues by looking at how metagenomics data is obtained...
