100
A visible population of microorganisms originating from a single parent cell and growing on a solid medium
What is a bacterial colony
100
The total magnification of a specimen with ocular lens magnification 10x and objective magnification 40x.
What is 400x
100
The creator of gram-staining
What is Hans Christian Gram
100
A medium that selects for the growth of one group of bacteria and inhibits the other.
What is a selective medium
100
Toxic by-products of oxygen utilization
What are hydrogen peroxide and oxides
200
A liquid culture medium used for bacterial growth.
What is broth
200
How well two objects can be distinguished from one another on a microscope
What is resolution
200
The dyes used in gram-staining
What are crystal violet and safranin
200
Media that support the growth of all bacteria but help you differentiate between different groups according to the reaction the bacteria has on the surface of the medium
What is differential media
200
Extremophiles microorganisms that thrive in high salt concentrations
What are halophilic bacteria
300
A needle-like shape of a bacterial colony
What is punctiform
300
The method used to identify the morphology and grouping of bacteria without retrieving any further information
What is simple staining
300
The de-colorizer used to wash away the crystal violet from gram-negative bacteria
What is ethanol
300
Bacteria that grows on EMB plate with a green metallic sheen
What is a gram-negative bacterium and a strong sugar fermenter
300
Microorganisms that grow better in O2, however, these bacteria can also grow in the absence of O2 with a lower growth rate
What are facultative anaerobes
400
The method used to isolate a single colony and have a pure bacterial culture.
What is isolation streaking
400
Bacterial morphology that is circular with 4 circular cells forming a square.
What is a coccus with tetrad arrangement
400
The gram-stained color of a gram-positive bacterial cell wall and that of gram-negative bacterial cell wall
What are purple and pink
400
Which bacteria can grow on a PEA plate?
What are gram-positive bacteria
400
A microorganism that thrives in extremely hot environments—from 60 °C upwards. The optimal temperature for the existence of hyperthermophiles is often above 80 °C.
What are hyperthermophilic bacteria
500
This sector has the highest bacterial population which is known as the "parent population"
What is sector 1
500
The step which allows bacteria to bind to the slide and breaks down the enzymes that can interfere with simple staining
What is heat fixing
500
The most important indicators of the success during gram-staining
What are the positive and negative controls
500
Which medium can bacteria that are purple in a gram stain grow (EMB or PEA)?
What is PEA plate
500
Microorganisms that can tolerate high pressures. They do not necessarily require these high pressures as they can grow and reproduce in less extreme environments along with high-pressure environments.
What are barotolerant bacteria
