27 Why should the prepared plate be inverted during culture?

 

 

 

1 Prevent the culture medium from detaching from the petri dish

 

 

 

2 petri plate is inverted for easy to take

 

 

3 Conducive to bacterial growth and reproduction

 

 

 

4 Prevent bacterial contamination during culture

 

 

5 Conducive to nutrient enrichment and observation and counting

 

When the plate is inverted for microbial culture, due to the influence of gravity, the nutrients in the culture medium will be concentrated on the surface of the culture medium and the sub-layer below the surface. This facilitates the growth and reproduction of microorganisms. At the same time, since the colonies do not spread too quickly, it is easier to identify the characteristics of the colonies during observation, which facilitates subsequent counting and analysis.
