Viruses, Viroids & Prions (not really “organisms”) WHAT IS MICROBIOLOGY? The study of small organisms. Viruses, Viroids & Prions (not really “organisms”) Prokaryotes: Bacteria & Archaea Eukaryotic Microbes: Algae Fungi “Protozoa”

LIFE IS DIVIDED INTO 3 DOMAINS

How small is small? MICRON or MICROMETER - 1 millionth of a meter (10-6 meters) - symbol is µ NANOMETER - 1 billionth of a meter (10-9 meters) Bacteria are usually several micrometers in diameter. Fungi are about 10+ micrometers in diameter

THE HISTORY OF MICROBIOLOGY We will look at natural history and human history

MICROBES ARE EVERYWHERE! • earliest life - 3.8 billion years old • represent more than half of the biomass (animals <15%) • almost every natural surface • important symbionts • vital to the ecosystem

BACTERIAL SYMBIONTS

MICROORGANISMS ARE VITAL TO NUTRIENT CYCLING

MICROBIAL GENETICS

MICROBIAL GENOMICS

FOOD MICROBIOLOGY Bread Cheese Yogurt Sauerkraut Wine Beer
