Diversity of Bacteria.

🤖 Plain-English Summary

Bacteria exhibit extraordinary evolutionary and ecological diversity. Despite advances in genomics and cultivation-independent methods, vast portions of bacterial diversity remain uncultured and poorly understood.

🔑 Key Findings

• They range from dominant, well-characterized phyla to rare lineages that are known only through environmental sequencing.
• This chapter reviews four key bacterial phyla, including Pseudomonadota, Bacillota, Actinomycetota, and Bacteroidota.
• These phyla are widely distributed, metabolically versatile, and play a central role in ecosystem functioning and human health.
