competitive exclusion - THE CORRECT ANSWER-a way to kill the bad
bacteria
- change in the pH
- secrete enzymes
- eat the food
bioremediation - THE CORRECT ANSWER-using microbes to clean up
pollutants
Bacillus thuringienisis - THE CORRECT ANSWER-can kill insects but
doesn't harm plants or animals
Order of the Scientific Method - THE CORRECT ANSWER-observe
hypothesis
prediction
experiment
,consistency
theory
law
Mycology - THE CORRECT ANSWER-study of fungi
bacteriology - THE CORRECT ANSWER-study of bacteria
virology - THE CORRECT ANSWER-study of viruses
algology - THE CORRECT ANSWER-study of algae
protozoology - THE CORRECT ANSWER-study of protozoa
Robert Hooke - THE CORRECT ANSWER-• All living organisms are
composed of little boxes or "cells"
• -came up with cell theory - that all microorganisms are made
up of cells
-marked the beginning of the cell theory
Anton van Leeuwenhook - THE CORRECT ANSWER-• 1st cells observed
under the microscope
also made the original electron microscope : 10 mil X
Rebecca Lancefield - THE CORRECT 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 - THE CORRECT 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 - THE CORRECT 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 - THE CORRECT ANSWER-Proved that bacterium causes
anthrax and provided the experimental steps of Koch's
Postulate
