Culture Types Of Agar Plates

Microbial growth media contains nutrients and an energy source to fuel the microbes as they grow and agar to keep the media in a semi solid gel like state.

Culture types of agar plates.

Before you can transfer and store mushroom cultures on agar you need properly made nutrient rich agar plates. Store nutrient agar plates in refrigerator. On solid media a single microbe will grow and divide to produce a colony a spot of identical descendants. The orange lines and dots are formed by bacterial colonies.

We have premade or called pre prepared nutrient agar plates made with sterile petri dishes at very affordable. The basic process for doing this is to mix up a nutrient rich agar solution pressure sterilize it and then pour the mix onto sterile dishes in a clean environment. Agar plates come with many different types of media or nutrients depending on the microorganism you want to culture. You can buy nutrient agar powder and sterile petri dishes and prepare nutrient agar plates by yourself.

Agar plates are the standard solid support material for growing microorganisms.

But it takes time and kind of messy and sometimes you can screw up your project. In the above picture of a mixed culture an agar plate that has been exposed to the air and many different colony morphologies can be identified.

Some colony types recur in various areas of the plate note 3 and 4. Baps are enriched differential media used to isolate fastidious organisms and detect hemolytic activity. An agar plate an example of a bacterial growth medium. Examples include streptococcus haemolyticus.

β hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony. Specifically it is a streak plate. Blood agar plates blood agar plates bap are made by adding five to ten percent sheep or horse blood to the nutrient medium.
