About this video
Microbes survive anywhere by mastering nutrients, oxygen use, and flexible metabolism—learn how these strategies drive infection, persistence, and lab diagnostics. This video explains microbial nutrient needs (macronutrients, trace elements like iron and siderophores), energy and carbon strategies (phototrophs, chemotrophs, autotrophs, heterotrophs), and why most pathogens are chemo-heterotrophs. Discover how oxygen shapes metabolism—obligate aerobes, obligate anaerobes, facultative anaerobes, microaerophiles, and aerotolerant species—plus the role of reactive oxygen species and defense enzymes (catalase, peroxidase, superoxide dismutase) in survival and diagnostic tests.
