Study Guide on Microbiology, Organic and Inorganic Compounds, and their Applications

Historians in Microbiology

• Father of Microbiology: Anton Van Leeuwenhoek.

• Disproof of Spontaneous Generation: Louis Pasteur.

  • Contributions:

  • Pasteurization: Process of heating liquids to kill harmful bacteria.

  • Fermentation: Studied the process and its applications.

  • Immunology: Developed vaccinations.

• Bacillus anthracis and Anthrax: Robert Koch

  • Known for Koch's Postulates which link a specific organism to a specific disease.

  • Purpose of Koch's postulates: To establish a causal relationship between a microbe and a disease. Not limited to bacteria; protozoans and viruses can also be studied, but viruses present growth challenges.

Aseptic Techniques

• Aseptic Practices in Nursing: Florence Nightingale.

• Aseptic Surgery: Joseph Lister, known for promoting sterile surgical techniques.

Organic vs. Inorganic Compounds

• Inorganic Compounds: Primarily acids, bases, and salts.

  • Identification of compounds (testing for acids vs bases vs salts):

  • A compound disassociates in water releasing a hydrogen ion (H⁺): it is an acid.

  • A compound disassociates releasing a hydroxide ion (OH⁻): it is a base.

  • A compound that disassociates into neither H⁺ nor OH⁻: it is a salt.

• Type of bond in ionic compounds: Ionic bond.

Identifying Compounds

• Examples:

  • Hydrochloric acid (HCl): Inorganic

  • Glucose (C₆H₁₂O₆): Organic

  • Lactase: Organic

  • Chloride salt: Inorganic

• Acids and bases are characterized by specific ions:

  • Acid characterized by H⁺ ions.

  • Base characterized by OH⁻ ions.
