Culture Types Of Agar Plates

Specifically it is a streak plate.

Culture types of agar plates.

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. The orange lines and dots are formed by bacterial colonies. Nine obviously different colonies are numbered. 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. An agar plate an example of a bacterial growth medium. 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. Blood agar plates baps contain mammalian blood usually sheep or horse typically at a concentration of 5 10.

Examples include streptococcus haemolyticus. Baps are enriched differential media used to isolate fastidious organisms and detect hemolytic activity. 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. A growth medium or culture medium is a solid liquid or semi solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation 1 or.

On solid media a single microbe will grow and divide to produce a colony a spot of identical descendants. But it takes time and kind of messy and sometimes you can screw up your project. Agar plates come with many different types of media or nutrients depending on the microorganism you want to culture. β hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony.

Starting with sterilized agar plates. We have premade or called pre prepared nutrient agar plates made with sterile petri dishes at very affordable. Blood agar plates blood agar plates bap are made by adding five to ten percent sheep or horse blood to the nutrient medium.
