Unit 1: Intro Flashcards
study of microorganisms
Microbiology
biological entities that are too small to be seen with our naked eye
Microbes
Major groups:
* Bacteria, Algae, Protozoa, Helminths,
and Fungi
* Viruses - noncellular; depend on cells for
replication
“Father of Microbiology” and inventor of high-power microscopy.
- He also Crafted >200 microscopes
Antonie van Leeuwenhoek
- In _____, he first to see bacteria (he called them
“_____”) in the rain, seawater, snow, and
the scum on teeth
1676, “wee animacules”
fundamental processes of life
(organisation, metabolism and reproduction)
Microbiology uses microbial cells to probe the fundamental processes of life (organization, metabolism and reproduction)
Basic biological science
Microbiology is at the forefront of many important breakthroughs in human and veterinary medicine, agriculture, and industry
Applied biological science
attempted to disprove the “Spontaneous Generation”
Lazaro Spallanzani
demolished “Spontaneous Generation”
Louis Pasteur
Developed method to Isolate and culture bacteria (Invented the 4 postulates)
Robert Koch
characterized bacterial nitrogen an sulfur transformations; described his work as “Microbial Ecology”, discovered virus TMV (Tobacco Mosaic Virus)
Martinus Beijerinck
discovered antibiotic penicillin and enzyme lysosome
Alexander Fleming
described Archaea and proposed three domains of life
Carl Woese
Invented Polymerase Chain Reaction (PCR)
Kary Mullis
Used genome sequencing to examine Sargasso Sea and identified 1.2 million previously unknown genes
Craig Venter
Introduces Kingdom Protista and the terms “Ecology and Monera”
Ernst Haeckel
Developed the concept of chemoautotrophy
Sergei Winogradsky
According to him, mice could arise from rags and wheat kernels left in an open container for 3 weeks.
Jan Baptista van Helmont
“Life from non-life“, “De novo synthesis”
“Living organisms spring forth from non-living materials”
Theory of Spontaneous Generation
earliest recorded scholars to articulate the theory of Spontaneous Generation
ARISTOTLE
First to refute the idea that maggots spontaneously on meat left out in the open air.
Francesco Redi
“Father of Modern Microbiology and Immunology”
Louis Pasteur
