Agar


Agar and the solidifying agents in solid growth media should be well chosen, with certain criteria to consider.

Agar is available in a range of qualities dictated by the target application. For example, Fluka brand agar (Cat. No. 05038) is highly purified and ideal when high transparency and brightness is needed, as in nutritional studies (Vitamin Assay Media) and sensitivity testing procedures, or when high purity and good diffusion of substances is essential. For identification and differentiation we recommend using a purified or even highly purified agar. However, when isolating a single colony in most cases a standard quality will suffice. Typical solid media has an agar concentration of 1.0 - 1.5%, to accommodate the requirements of different applications and growth habits of the target microorganisms. For more details please contact our technical service Flukatec@europe.sial.com.
