pasteurize

Examples of pasteurize in the following topics:

• Pasteur and Spontaneous Generation

  • Louis Pasteur's 1859 experiment is widely seen as having settled the question.
  • In summary, Pasteur boiled a meat broth in a flask that had a long neck that curved downward, like a goose.
  • Many of these residual objections were routed by the work of John Tyndall, succeeding the work of Pasteur.
  • By sterilizing a food source and keeping it isolated from the outside, Pasteur observed no putrefaction of the food source (top panel).
  • Upon exposure to the outside environment, Pasteur observed the putrefaction of the food source (bottom panel).

• Achiral Diastereomers (Meso-Compounds)

  • Investigations of isomeric tartaric acid salts, carried out by Louis Pasteur in the mid 19th century, were instrumental in elucidating some of the subtleties of stereochemistry.

  • HH_LName=Pasteur).

• History of Microbiology: Hooke, van Leeuwenhoek, and Cohn

  • By boiling the broth beforehand, Pasteur ensured that no microorganisms survived within the broths at the beginning of his experiment.
  • Nothing grew in the broths in the course of Pasteur's experiment.
  • Thus, Pasteur dealt the death blow to the theory of spontaneous generation and supported germ theory instead.
  • The famous scientist Louis Pasteur, one of the founders of microbiology.
  • Explain how Van Leeuwenhoek, Spallanzani, Pasteur, Cohn and Koch contributed to the field of microbiology

• Origins of Antimicrobial Drugs

  • The era of antimicrobials begins when Pasteur and Joubert discover that one type of bacteria could prevent the growth of another.
  • The history of antimicrobials begins with the observations of Pasteur and Koch, who discovered that one type of bacteria could prevent the growth of another.

• Productivity Gains in Agriculture

  • Pasteurization of milk allowed it to be shipped by railroad.
  • (It was noted that calves fed pasteurized milk were less likely to develop tuberculosis, and soon it was found that pasteurization reduced the incidences of several other diseases in humans. ) Keeping livestock indoors in winter reduces the amount of feed needed.

• Antibiotic Discovery

  • Louis Pasteur observed, "if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics".
  • Antibiosis was first described in 1877 in bacteria when Louis Pasteur and Robert Koch observed that an airborne bacillus could inhibit the growth of Bacillus anthracis.
  • Louis Pasteur was a French microbiologist and chemist best known for their experiments supporting the Germ theory of disease, and for his vaccinations, most notably the first vaccine against rabies.

• Modern Microbiology

  • Louis Pasteur and Robert Koch were contemporaries of Cohn's and are often considered to be the father of microbiology and medical microbiology, respectively.
  • Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation, thereby solidifying microbiology's identity as a biological science.
  • Pasteur also designed methods for food preservation (pasteurization) and vaccines against several diseases such as anthrax, fowl cholera, and rabies.
  • While Pasteur and Koch are often considered the founders of microbiology, their work did not accurately reflect the true diversity of the microbial world because of their exclusive focus on microorganisms having direct medical relevance.

• Intro and major themes

  • Pasteur thought um, no stuff doesn’t just magically become alive, but he had to prove it.
  • Pasteur Flask helped prove that it was not magic that living things came from

• Discovery and Detection of Viruses

  • Viruses were first discovered after the development of a porcelain filter, called the Chamberland-Pasteur filter, which could remove all bacteria visible in the microscope from any liquid sample.
  • In 1892, Dmitri Ivanowski showed that this disease could be transmitted in this way even after the Chamberland-Pasteur filter had removed all viable bacteria from the extract.

• Fermented Foods

  • Historically, when studying the fermentation of sugar to alcohol by yeast, Louis Pasteur concluded that the fermentation was catalyzed by a vital force, called "ferments," within the yeast cells.
