microbial ecology - correct Answer-the study of the rela onship between microorganisms and
their environment
compe ve exclusion - correct Answer-a way to kill the bad bacteria
- change in the pH
- secrete enzymes
- eat the food
bioremedia on - correct Answer-using microbes to clean up pollutants
Bacillus thuringienisis - correct Answer-can kill insects but doesn't harm plants or animals
,Order of the Scien fic Method - correct Answer-observe

theory
law
Mycology - correct Answer-study of fungi

Robert Hooke - correct Answer-• All living organisms are composed of li le 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 - correct Answer-• 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
, Rebecca Lancefield - 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 - correct Answer-• discovered phenol: was used to stop surgical would infec ons
• usually in hospitals : Staphylococcus aures aka staph infec on
at least 20% of popula on is a carrier for the staph infec on and they carry it in their noses
Louis Pasteur - correct Answer-• father of microbiology and is the most important scien st in
microbiology
• showed that microbes are responsible for fermenta on
• Fermenta on: conversion of sugar to alcohol in the absence of air
• Discovered that pasteuriza on was something that could stop food spoilage
• Pasteuriza on: the applica on of a high heat for a short me to kill harmful bacteria in
beverages
How was he lucky in his discovery of pasteuriza on?—there we're no endospores and that
would should have been detected during the search for spontaneous genera on but it didn't
Robert Koch - correct Answer-Proved that bacterium causes anthrax and provided the
experimental steps of Koch's Postulate
Edward Jenner - correct Answer-• Discovered vaccina on (or the process of vaccina on)
Did it through using cow parts to vaccinate a child to protect against small pox
Alexander Fleming - correct Answer-• Discovered the 1st an bio c
• It was penicillin and it was totally found by accident
