Mycology
The study of algae
Phycology
The study of Protozoa
Protozoology
The study of viruses
Virology
Name some things that microorganisms play a big role in
Disease production, food contamination & spoilage, alcoholic beverage production, waste degradation
Name some importance of microorganisms
Play a major role in recycling essential elements; benefit society by their production of food, beverages, antibiotics and vitamins
Father of the microscope
Antonie van Leeuwenhoek ; first described microscopic organisms using scope
Stated that all cells arise from preexisting cells (biogenesis)
Rudolph Virchow
Theory of spontaneous generation
Abiogenesis
Living organisms can arise spontaneously from no living material. Ex) frogs from mud OR maggots from meat (Francesco Redi)
What happened during the golden age of microbiology?
Many disease producing organisms discovered; they grow best at body temperature; gained a better understanding of the role of immunity and ways to control and prevent infection by microbes
What is pasteurization?
Heating alcohol just enough to kill bacteria; solves spoilage problems; developed by Pasteur
High-temperature, short-time pasteurization
It takes typically 72 degrees C for about 15 seconds as opposed to 63 degrees C for 30 minutes
*Also, cold & freezing temperatures are not as effective in killing bacteria as high temperatures
Describe Germ Theory of Disease
Scientists began to suspect that microorganisms might have an influence on human disease; Joseph Lister began using disinfectants to soak bandages which greatly reduced infections and deaths
Provided indirect evidence that microorganisms were the casual agents of disease; developed the idea of sterilizing tools for operations; Greatly reduced infections and deaths
