    Study Notes

    The Science of Microbiology

    • Microbiology revolves around two interconnected themes: understanding microscopic organisms and applying knowledge for human and planetary benefits.

    Importance of Microorganisms

    • First living organisms on Earth
    • Found everywhere life is possible
    • Most numerous organisms on the planet
    • Global ecosystem depends on their activities
    • Influence human society in many ways

    Basic and Applied Microbiology

    • Basic Microbiology: studies the fundamental nature and properties of microorganisms
    • Applied Microbiology: employs knowledge to control and use microorganisms beneficially

    The Future of Microbiology

    • Keeps us healthy
    • Keeps the environment clean
    • Makes air breathable
    • Supports and protects crops
    • Provides new sources of medicine
    • Helps with food digestion

    A Brief History of Microbiology

    • Historical roots date back to A. Hooke, van Leeuwenhoek, and Cohn (discovery linked to the microscope invention)

    Louis Pasteur

    • French chemist
    • Disproved spontaneous generation theory using the swan-neck flask
    • Developed the Germ Theory of Fermentation (wine making)
    • Developed the Germ Theory of Disease
    • Introduced sterilization and pasteurization

    Robert Koch

    • German physician
    • Developed methods for studying bacteria in pure culture
    • Established Koch postulates (criteria to prove a microbe causes a disease)

    Joseph Lister

    • English surgeon
    • Introduced the concept of aseptic technique
    • Developed antiseptic surgery
    • Known as the "father of antiseptic surgery"

    Developments in Nonmedical Microbiology

    • Martinus Beijerinck and the Enrichment Culture technique
    • Sergei Winogradsky and the concept of chemolithotropy

    Other Key Figures

    • Angelina Fannie Hesse: suggested using agar instead of gelatin
    • Julius Richard Petri: developed the Petri dish

    Landmarks in Microbiology

    • Various discoveries and milestones in microbiology over the past 65 years
