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?
Previous answer: "because of infection" This person is obviously trying to be funny, the right word should be "Contamination", as for spread plate, the bacteria is more exposed to air as it is spread over the agar plate. Therefore, the result might not be accurate, as it might be contaminated. As for the pour plate method, the bacteria is in the agar itself, it is not exposed to air, thus, less risk of getting contaminated.
What is the lawn plate method?
The lawn plate method is a microbiological technique used to assess the antimicrobial activity of substances, such as antibiotics or disinfectants. In this method, a bacterial culture is evenly spread across the surface of an agar plate to form a "lawn" of bacteria. Small wells or disks containing the test substances are then placed on the agar, and after incubation, the zones of inhibition around the wells or disks indicate the effectiveness of the antimicrobial agent against the bacteria. This method is widely used in research and clinical settings to evaluate new antimicrobial compounds.
Who was the first to developed the culture plate method to identify pathogens?
Rober Kock developed the culture plate method to identify pathogens.
How do the results of pour plate method compare with those obtained using the streak plate and spread plate method?
In the pour plate, the microorganisms will grow within the gel that has been set, and in the spread-plate technique, growth will be on top of the agar gel where it has been spread.

Do both the spread-plate and pour-plate method in a experiment produce similar bacterial counts or are they vastly different?
Both Spread-plate and pour plate method don't give the same results. Because in the case of spread plate method the inoculmn used for inoculation can't be spread in a exact volume. A little inoculmn remains stick with the spreader after spreading. On the other hand, in pour plate method it doesn't happen. So mostly, through comparing the counts by both methods, less counts are obtained in spread plate method. I am Working as a Sr. Microbiologist in a Biotech company
What is Two methods for obtaining isolated colonies?
Two common methods for obtaining isolated colonies are the streak plate method and the spread plate method. In the streak plate method, a sterile inoculating loop is used to spread a diluted microbial sample across the surface of an agar plate in a series of streaks, which helps to separate individual cells. The spread plate method involves diluting the microbial sample and evenly spreading a small volume across the surface of an agar plate using a sterile spreader, allowing colonies to grow from individual cells. Both techniques aim to achieve isolation for further study or identification of microorganisms.

Advantages of pour plate method over other methods of bacterial colony?
The purpose of the spread-plate technique is to grow and isolate colonies of bacteria. A sample of bacteria is transferred to the agar plate, an environment that provides nourishment for the bacteria to grow. The bacteria sample is applied to the agar plate which a special streaking technique that dilutes the amount of bacteria in each section of the agar plate continuously. This is because if you just swabbed the bacteria onto the plate with no special technique the colonies would grow very densely together and be difficult to study. The streaking technique gradually dilutes the amount of bacteria in each 'quadrant' of the plate, so the last quadrant should have small, isolated colonies that can be easily studied. The spread plate technique is also used for the eneumeration of aerobic microorganisms from the given sample. This can be done by serial diluting the samples, placing 0.1ml of the diluted sample in the middle of an agar plate and spreading the sample over the surface with a help of an L-rod. After the incubation rhe colonies can be counted.

What is a glass spreader?
You may be referring to a " hockey stick. " This is a short glass rod bent in a hockey stick shape and it is used to spread cells on a cell plate after they have been delivered to the plate by microliter pipette.

it is the plate under the plate (kea nga UNDER plate!!!) hahaha
