Micro 13: Bacterial Metabolism and Genetics

Clinical Deep Dives · Feb 16, 2026 · 41m

This episode enters the bacterial interior. Drawing from Murray’s chapter, it explores how bacteria generate energy, synthesise essential components, and adapt genetically to changing environments. Metabolism is framed not as biochemistry for its own sake, but as a determinant of growth conditions, tissue tropism, and laboratory identification.

Aerobic versus anaerobic pathways, fermentation, nutrient requirements, and metabolic flexibility explain why some organisms thrive in oxygen-rich lungs while others dominate oxygen-poor tissues. Growth curves and environmental resilience underscore…
