Rober Kock developed the culture plate method to identify pathogens.
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.
No, Blood Agar does not support viral cultivation. If you have a nutrient agar plate with a lawn of cells coating the surface, you could add viruses to the lawn and the viral culture will survive on the plate by infecting the cells in the lawn, clearing them as the cells are lysed. The areas of clearance on the plate are called plaques.
Satellites are used to measure the movement of plate by radiation.
American microbiologist Robert Koch is credited with discovering the streaking method in the late 1800s. This method involves spreading a bacterial sample on an agar plate to isolate individual colonies for further study.

Alsalam alkom There is a difference between the two term (lawn culture and streak culture), if you used a loop for making new culture from primary culture you called that streaking method (like ABC streaking method), while if you used swab and streaked almost all the plate then, you can say (lawn culture).. In conclusion to the above 1- streaking is used to purify the bacterial culture (i.e to make well isolated colony) 2- lawn culture is used for antibiotic sensitivity tests Ali Maki .

Mine is on a plate located under the seat.
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.
The streak plate method makes it easier for colonies of bacteria to grow. It also generally leads to individual colonies that look like small dots, rather then simply a mat of bacterial growth.

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
Pour plate method
When bacteria is grown in an Agar plate, one quantitative method to measure growth is using a counting chamber. Another method is using viable plate counts.
A popular method is to use 791 style sticky tape. I find this is a very effective method A popular method is to use 791 style sticky tape. I find this is a very effective method
