BIOD 171 MICROBIOLOGY MODULE 6
PRACTICE QUESTIONS AND DETAILED
SOLUTIONS
◉ Rebecca Lancefield.
Answer: • came up with the system that help classifying different
microorganisms
• it was all based on different polysaccharides in the cell wall
also helped discover Streptococcus pyognes - which is basically
strep and we know this because pyognes is a pus forming
microorganism
◉ Joseph Lister.
Answer: • discovered phenol: was used to stop surgical would
infections
• usually in hospitals : Staphylococcus aures aka staph infection
at least 20% of population is a carrier for the staph infection and
they carry it in their noses
◉ Louis Pasteur.
Answer: • father of microbiology and is the most important scientist
in microbiology
• showed that microbes are responsible for fermentation
,• Fermentation: conversion of sugar to alcohol in the absence of air
• Discovered that pasteurization was something that could stop food
spoilage
• Pasteurization: the application of a high heat for a short time to kill
harmful bacteria in beverages
How was he lucky in his discovery of pasteurization?—there we're
no endospores and that would should have been detected during the
search for spontaneous generation but it didn't
◉ Robert Koch.
Answer: Proved that bacterium causes anthrax and provided the
experimental steps of Koch's Postulate
◉ Edward Jenner.
Answer: • Discovered vaccination (or the process of vaccination)
Did it through using cow parts to vaccinate a child to protect against
small pox
◉ Alexander Fleming.
Answer: • Discovered the 1st antibiotic
• It was penicillin and it was totally found by accident
Staphylacoccus agnues
, ◉ Agostino Bassi.
Answer: Believed that silk worm disease was caused by a fungus
◉ Ignaz Semmelweis.
Answer: • 1st person that came up with hand washing
starting with delivering babies and babies we're dying and then
when they washed their hands the death rate when way down
◉ Woes.
Answer: discovered the 3 domains and they were all based on the
sequences of nucleotides in rRNA
◉ Carols Linnaeus.
Answer: established the system of scientific nomenclature
◉ Spontaneous Generation.
Answer: the hypothesis that life arises from non living matter ; a
vital force is necessary fro life
disproven by Louis Pasteur
◉ Biogenesis.
