Metagenomics for Microbiology, Second Edition demonstrates the complexity and diversity of microbial communities and its important roles in health and disease and in ecosystem function. This new edition highlights remaining challenges and promising approaches making metagenomics research more tractable leading to efficacious translation of microbiota-based applications. Each chapter is fully updated along with over five new chapters on the most recent research data and analysis thereof to move forward our understanding of microbial principles, Metagenomics for Microbiology, Second Edition continues to provide a solid base for the design and analysis of omics studies for the characterization of microbial consortia focusing on the technological underpinnings of metagenomic approaches and their conceptual and practical applications.
