An agar plate or Petri dish is used to provide a growth medium using a mix of agar and other nutrients in which microorganisms, including bacteria and fungi, can be cultured and observed under the microscope.Agar is indigestible for many organisms so that microbial growth does not affect the gel used and it remains stable. Agar is typically sold commercially as a powder that can be mixed with Making Agar Plates for Bacterial Growth. Contamination is critical, as you are providing a platform for bacteria and yeast to grow. They both exist naturally on our skin and in the air, so gloves are a necessity. STEP 2: Weigh out your LB AGAR on your digital scale. These agar plates provide a solid medium on which microbes may be cultured. They remain solid, as very few bacteria are able to decompose agar.

Being kept in one place, the resulting cells have accumulated to form a visible patch. Most bacterial colonies appear white, cream, or yellow in color, and fairly circular in shape. One might ask why agar, as opposed to regular gelatin (like that found in Jello), is used for As microbiologists combined different formulations of nutrients with agar to grow a diverse set of microorganisms, they created another tool for microbial identification: selective and differential media that help microbiologists identify bacteria and yeast species.

Spores that are able to reproduce can settle on the dish and and use the agar as nutrients for growth, and within days you can view the mold or bacterial growth in what’s called colony forming units (CFU). Blood Agar Discussion This agar is a differential medium intended to depict the different bacteria responses in red blood cells. After the incubation of 24 hours, the blood agar plate was observed to have completed β (beta) hemolysis. A single colony should look like a white dot growing on the solid medium. This dot is composed of millions of genetically identical bacteria that arose from a single bacterium.
Peptone is the principal source of organic nitrogen for the growing bacteria. 0.3% beef extract/yeast extract plate, as it binds on unhydrolyzed protein in the plate. The bacterium, Bacillus subtilis strain VV grown on BCG-casein agar plates.

The agar serves as food for the bacteria. Growing bacteria can be tricky so dont give up if your first couple of attempts fail. Once you have them growing, count the number of colonies and note the differences in colour, shape and other properties. Did you find more bacteria on … Tips: Always label each plate clearly with a sharpie/marker pen; Always have correct controls; If you have more than 10 interested surfaces you can draw a “+” on the bottom of the petri dish (agar side, not the lid).
