How does glucose concentration affect the growth of bacteria?
the greater the conentraion, the faster the growth of bacteria. it is an energy source.
Agent that slows or stops the growth of bacteria?
Antibiotics inhibit the growth of bacteria.
What is confluent growth?
A continuous bacterial growth covering all or part of the filtration area of a membrane filter in which the bacteria colonies are not discrete.
What are the three types of hemolysis bacteria can exhibit?
1. Alpha- which will appear on a blood agar plate with a slightly greenish growth. 2. Beta- will appear as growth which obvious lysis surrounding the bacteria. 3. Gamma- appears as just a slightly yellow growth
What is the different between bactericidal and bacteriostatic?
BACTERIOCIDE: The agent which kill bacteria is called bacteriocidal it can be done by heat of any chemical. BACTERIOSTATIC: The agent which inhibit the growth and reproduction of bacteria but do not necessasarily kill the bacteria.
What media are use to determine motility and growth patterns of bacteria?
SIM test
What are the three different growth patterns of bacteria?
Diplo- is a prefix that refers to a paired arrangement of cell growth. The prefix Staphylo- describes an arrangement of cells that resemble grapes. Strepto- is a prefix that refers to an arrangement of chains of cells. ( hope this helps)
What is the predictable order of growth patterns?
What is the preditable order of growth patterns referred to
What is the film of cells at the surface of a broth called?
When bacteria are grown in broths such as trypticase soy broth (TSB), they may exhibit patterns of growth ranging from a sediment at the bottom of the tube, turbid growth throughout the tube, or a pellicle (thick growth at the top of the tube).
What effect does Mercurochrome have on bacteria?
It will affect the growth of the bacteria.
How does glucose concentration affect the growth of bacteria?
the greater the conentraion, the faster the growth of bacteria. it is an energy source.
What bacteria are required for plant growth?
Symbiotic bacteria
Agent that slows or stops the growth of bacteria?
Antibiotics inhibit the growth of bacteria.
Do Bacteria Affect Plant Growth?
It increase plant growth.
What is confluent growth?
A continuous bacterial growth covering all or part of the filtration area of a membrane filter in which the bacteria colonies are not discrete.
Is acute necrotizing ulcerative gingivitis is caused by the abnormal growth of bacteria in the mouth?
Abnormal growth of bacteria in the mouth.
Why do bacteria grow weak in the freezer?
Bacteria all have a specific optimum growth temperature. When the temperature is not at the optimum, growth is slowed down. When it is too cold, the bacteria will still be alive, but growth will be very slow and spoilage will happen slower.
