Micro test 1 Flashcards
Reactive Oxygen Species
- superoxide
2.Hydrogen Peroxide - Hydroxyl Radical
Oxygen concentrations
Obligate anaerobe- will die in O2
Obligate aerobe- need O2
Facultative anaerobe- can live without O2 but live better with it
Aerotolerant- can live with or without O2
Microaerophile- need reduced amounts of O2
Aerobe protective enzymes
- SOD
- Catalase
- Peroxidase
What formation does the Z-ring proceed?
Formation of the septum and fill splitting of the cell
Protein responsible for helping the Z-ring?
FtsZ
Which protein keeps out target cells in the middle
MinA by oscillating
Robert Hooke
1.First to observe microorganisms
2. Creator of the compound microscope
Carl Woese
Distinguished the 3 domains based on rRNA sequences
Leeuwenhoek
Father of microbiology
First to accurately describe microorganisms
Koch
Created Koch’s postulates help find the cause of diseases
Francesco Redi
Put decaying meat in different containers in order to see if maggots would appear. Concluded that maggots only appeared in the open container
John Needham
Saw that after boiling a solution with hay, some microorganisms still appeared. Supported spontaneous generation
Lazzaro
Did similar experiment as needham but sealed the container and found that microbes didn’t appear. Supported biogenesis
Pasteur
Used swan-neck flasks that to show that after boiling a solution and exposing it to air, microbes didn’t appear.
Comma shaped
Vibrio
