A hockey stick is used
when spreading bacteria over a solid medium
.
What is the purpose of spread plate method?
The spread plate method is a
technique to plate a liquid sample containing bacteria so that the bacteria are easy to count and isolate
. A successful spread plate will have a countable number of isolated bacterial colonies evenly distributed on the plate.
What is the function of hockey stick in microbiology?
The hockey stick is “air cooled.” The sterilized hockey stick is
used to spread the dye across the agar surface
. It is important that the hockey stick be held level with the agar surface. The bend in the glass should be close to the outer edge of the plate.
What is streaking in biology?
In microbiology, streaking is
a technique used to isolate a pure strain from a single species of microorganism, often bacteria
. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested.
How do you describe a hockey stick?
An ice hockey stick is
a piece of equipment used in ice hockey to shoot, pass, and carry the puck across the ice
. Ice hockey sticks are approximately 150–200 cm long, composed of a long, slender shaft with a flat extension at one end called the blade.
What is a pure culture and why is it important in microbiology?
As developed by Koch, pure cultures
allow the pure isolation of a microbe
, which is vital in understanding how an individual microbe may contribute to a disease.
What is a pour plate?
In a pour plate,
a small amount of inoculum from a broth culture is added by pipette to the centre of a Petri dish
. Cooled, but still molten, agar medium in a test tube or bottle is then poured into the Petri dish.
What is the difference between pour plate and spread plate method?
The key difference between Pour plate and Spread plate is that
a known volume of the sample is spread on the surface of the agar medium in spread plate
, while, in pour plate, a known volume of the sample is mixed with agar and then poured into a plate.
How do you plate bacteria on agar?
- Hold loop with bacterial sample parallel to fresh plate.
- Gently rub loop across surface spreading bacteria thinly throughout.
- Flip loop on other side or even gently drag edges across plate if visible bacteria still needs to be delivered.
What is the difference between streak plate and spread plate technique?
The key difference between streak plate and spread plate is that
the streak plate is used to isolate and purify a particular bacterial species from a mixture of bacteria
while the spread plate is used to enumerate and quantify bacteria in a sample.
What are the 3 categories of bacteria morphology?
Most bacteria come in one of three basic shapes:
coccus, rod or bacillus, and spiral
.
What is the purpose of streaking?
As you might guess, the purpose of streaking for isolation is
to produce isolated colonies of an organism on an agar plate
. This is useful when you need to separate organisms in a mixed culture or when you need to study the colony morphology of an organism.
What is the purpose of quadrant streaking?
In order to obtain well-isolated discrete colonies, the quadrant streak technique should be used. This
allows sequential dilution of the original microbial material (broth culture or colonies on a plate or slant) over the entire surface of a fresh plate.
What is an illegal stick in hockey?
An illegal hockey stick refers to
a playing stick that violates the outlined rules regarding the material, length, width, and curve of both the blade and shaft of the stick
. … No projections are allowed on the stick in order to keep players safe on the ice.
