• LOUIS PASTEUR french chemist, discovers what occurs during ALCOHOLIC FERMENTATION.

  he coined "MICROBIOLOGY aerobes and unaerobes"
• LOUIS PASTEUR develops a process known as PASTEURIZATION

  developed vaccines to prevent chicken pox, cholera, anthrax,
• LOUIS PASTEUR developed vaccines to prevent rabies
• JOHN TYNDALL discovered highly resistant bacterial structure later known as ENDOSPORE.
• JOHN TYNDALL concluded that prolonged boiling or intermittent heating was neccesary to kill spores, a process called TYNDLLISATION.
• LORD JOSEPH LISTER father of ANTISEPTIC SURGERY.

  concluded that wound infection are caused by microorganisms
• LORD JOSEPH LISTER devised a method to destroy microbes by spraying CARBoLIC ACID into the air.
• ROBERT KOCH a german physician, proved that anthrax bacillus (B. Anthracis) was the causative agent of anthrax.

  > discovered that B.anthrax produces spores.

  > developed methods of fixing, straining and photogrphing bacteria.
• ROBERT KOCH developed methods of cultivating bacteria on solid media

  > discovered the bacterium (M. TUBERCULOSIS) that causes tuberculosis and the bacterium (VIBRIO CHOLERAE)that causes cholera.
• Frau Hesse - AGAR
• KOCH'S POSTULATES experimental procedure to prove that a scientific microbe is the cause of a specific infectious disease published in 1884
• FANNE EILSHEMIUS HESSE koch assistant.

  > first proposed the use of AGAR
• AGAR better than gelatin because of its higher melting pointing 96c and solidifying 40-45c points.
• RICHARD PETRI developed the PETRI DISH

  PETRI DISH a container used for solid culture media
• EDWARD JENNER first to prevent small pox and discovered technique of vacinnation
• PAUL ERLICH discovered treatment of syphilis.
