Terms
A liquid culture that contains the nutrients the microbe needs.
What is a broth culture?
A tough structure that protects a dormant bacterium, allowing it to become freely living once the external conditions become suitable for life.
What is an endospore?
The type of microscope we use for our labs.
What is a light microscope?
Extremophiles belong to this domain.
What is archaea?
The process of adding a sample of bacteria to a culture.
What is inoculation?
The study of blood serum and immune responses.
What is serology?
A subtype of organism within the species grouping, sometimes called a serotype.
What is a strain?
A solid culture that contains the nutrients the microbe needs.
What is agar culture?
If a bacterium is rod shaped, it probably has this word as part of it's name.
What is bacillus?
This type of Archaea is not named for the conditions under which it lives.
What are methanogens?
Organisms that must have oxygen in order to survive.
What are obligate aerobes?
Extremophiles that live in very salty conditions.
What are halophiles?
This type of microscope has the greatest magnification.
What is a scanning tunneling microscope or STM?
The type of extrmophiles you would find in the hot springs and geysers at Yellowstone National Park.
What are thermophiles?
A differential dye technique that allows identification of bacteria that have a combination of fatty acids, waxes, and complex lipids in their cell walls.
What is the acid-fast stain?
Reproduction of viruses using the host cell's biomachinery, resulting in lysis of the host cell to release the visions.
What is the lytic cycle?
The conversion of atmospheric nitrogen into a nitrogen-containing molecule that organisms can use.
What is nitrogen fixation?
A differential dye applied to divide bacteria into two distinct groups.
What is the Gram stain?
Gram-positive bacteria can be split into these two groups.
What are firmicutes and actinobacteria?
This member of domain Bacteria produces a significant amount of oxygen for the atmosphere.
What is cyanobacteria?
Organisms that can perform aerobic respiration but can switch to fermentation when little or no oxygen is present.
What are facultative anaerobes?
Sometimes called a temperate infection, this occurs when a viral nucleic acid is inserted into the host genome and replicates as the host replicates.
What is the lysogenic cycle?
When a Gram stain is applied, gram-positive bacteria appear this color, while gram-negative bacteria appear this color.
What is purple and red?
The presence of this chemical in the cell wall is used to differentiate Bacteria from Archaea.
What is peptidoglycan?
You would expect to find this macromolecule within a cell infected by a virus.
What are nucleic acids?
