An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. 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 small plants like the moss Physcomitrella patens. [2]
After the desired level of growth is achieved, agar plates can be stored upside down in a refrigerator for an extended period of time to keep bacteria for future experiments. There are a variety of additives that can be added to agar before it is poured into a plate and allowed to solidify. Some types of bacteria can only grow in the presence ...
Chemotaxis assays with agar plates. This way of evaluation deals with agar-agar or gelatine containing semi-solid layers made prior to the experiment. Small wells are cut into the layer and filled with cells and the test substance.

1.5% agar - this gives the mixture solidity; 0.5% sodium chloride - this gives the mixture proportions similar to those found in the cytoplasm of most organisms; distilled water - water serves as a transport medium for the agar's various substances; pH adjusted to neutral (6.8) at 25 °C (77 °F). Nutrient broth has the same composition, but ...
