What is responsible for solidifying nutrient agar plates?
Agar
What is the suitable media for the gram positive bacteria?
Gram negative gastrointestinal bacteria, colonies such as E.coli can usually be isolated on simple agar plates, incubated at roughly 37 degrees. Other plates can be used if you want to isolate certain aspects of the colony, but usually agar is the first choice.
What type of media is used for growing a culture from a throat specimen?
blood and chocolate agar plates as well as in universities laboratory Nutrient agar plates are also provided
Why the inoculated agar medium plate must be inverted position in incubator?
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.
What field of biology is observing colonies of bacteria?
microbiology normal the bacteria are grown on agar plates atsrting out with a dense area and spread out to in the end isolate individual colonies and have some hope of identifying them
Why Plate Count Agar is used?
it is used to count the colonies
How do the colonies on the surface of the pour plates differ from those suspended in the agar?
How do colonies on the surface of a pour plate differ from those suspended in the agar?
Can macConkey Agar plates test for e coil?
Yes. Colonies will be red or pink.
Why is condensation on the agar undesirable?
It'll cause the spreading of the colonies that are growing on the agar surface if the condensed water falls on them. That's why usually the plates are inverted during incubation.

Does pseudomonas aeruginosa grow on blood agar?
Yes, Pseudomonas aeruginosa can grow on blood agar, but it may not show the typical hemolysis patterns like other bacteria. It usually appears as flat, greenish colonies on blood agar plates.
Why are agar plates dried before being used for the preparation of dilution streak plates?
perhaps it is easier to streak that way, i mean when the agar is set and dry. .
What type of media is used for growing a culture from a throat specimen?
blood and chocolate agar plates as well as in universities laboratory Nutrient agar plates are also provided
What are unopened agar plates referred called?
they are the controlled plates
Why the inoculated agar medium plate must be inverted position in incubator?
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.
Does the stench produced by my agar plates mean bacteria is growing?
Yes bacterial colonies growing on agar plates tend to metabolize the medium leaving "fermented" waste products that are generally of foul odor. You should also be able to spot clusters of spots forming to confirm this hypothesis
