CoachThe hockey stick is used to spread the microbial inoculum evenly across the agar surface in a spread plate method. By dragging the hockey stick back and forth over the agar surface, it helps to distribute the microbes in a consistent and uniform manner, promoting even colony growth.

What is the function of a hockey stick in microbiology?
In microbiology, a hockey stick is a tool used for streaking bacterial cultures on agar plates to isolate individual colonies. By dragging the stick across the plate, the bacteria are spread out in a way that allows for distinct colonies to grow. This helps microbiologists study and identify different strains of bacteria.
What are 3 methods used to isolate microorganisms from a mixed culture?
It is necessary to make the colonies well-isolated from each other so that each appears distinct, large and shows characteristic growth forms.Most bacteria, many other microfungi, and unicellular microalgae, may be most commonly obtained by plating methods such as streak plate method, pour plate method and spread plate method.
What is the main advantage of pour-plate method over other methods of bacterial colony isolation?
The main advantage of the pour-plate method is that it allows for the even distribution of bacteria throughout the agar, resulting in isolated colonies both on the surface and within the agar. This method gives accurate colony count and provides easy identification of different colony types present in the sample.
Who was the first to developed the culture plate method to identify pathogens?
Rober Kock developed the culture plate method to identify pathogens.
What is the type of plating technique that is probably performed when using the above dilution technique?
The plating technique most likely performed when using the dilution technique is spread plating. In spread plating, a sample is spread over the surface of the agar plate using a sterile spreading tool to obtain individual colonies. This method helps to isolate and quantify bacteria present in the sample.
