Abbreviation of Zhonghai biological plate counting agar medium

  Plate counting agar medium (PCA) plate counting agar medium, also referred to as PCA, is used for the determination of the total number of colonies
This medium is a non selective solid medium, and its main components include tryptone, yeast extract, glucose and agar
Tryptone provides organic nitrogen source and free amino acid
Yeast extract powder is rich in nutrients, which can provide growth factors for microorganisms, and glucose is used as energy material
The nutrients in CNOOC biotechnology plate counting agar medium 1300-1 ⑨ 30-979 can meet the growth of most microorganisms
The total number of microbial colonies was determined

[product features]
Plate counting agar medium is mainly used to determine the total number of colonies
Its quality will affect the growth of microorganisms and directly affect the accuracy of the total number of colonies The raw material composition of Sea plate counting agar medium in com is relatively fine, and the production process is more advanced, so it is more rapid in terms of dissolution speed, which greatly improves the work efficiency for the determination of the total number of colonies, and the growth rate of the culture medium control strain can meet the requirements of relevant standards

[application field]
Scientific experimental research and other fields

[usage]
Weigh 23
5g of plate counting agar medium, add 1L of purified water or water for injection, heat and boil until it is completely dissolved, then repack, and then autoclave at 116 ℃ for 30 minutes

[precautions]
1
Please wear disposable gloves and masks for operation, and avoid contact with hands and mouth

2
It is not allowed to continuously take multiple media with the same tool at the same time

3
Please close the bottle cap after taking it
Do not misplace the bottle cap and tools
Put the bottle back in time after use to avoid forgetting and inconvenience

4
Pay attention to aseptic operation
The removed reagent cannot be put back into the original reagent bottle to avoid microbial pollution

5
When used for pouring counting, the temperature of pouring medium is too high, which will damage or scald the microorganisms in the sample and affect the counting results
Generally, the pouring temperature is required to be about 45 ℃
Therefore, the
