Agar Bacteriological (Agar No. 1, Oxoid) is a clear purified high gel strength bacteriological agar compatible with all culture media. This agar has low calcium (Ca) and magnesium (Mg) levels and has very high working gel strength (1.5% w/v).

Agar Bacteriological, Oxoid is compatible with all culture media. It can be formulated to either broth or agar of the same medium with very similar metal values. This characteristic is especially valuable in antimicrobial MIC studies where differences in mineral/metal content can profoundly influence the results. Due to the low mineral/metal content in Agar Bacteriological, Oxoid, it allows free diffusion of antimicrobial substances. As a result, it is a highly satisfactory agar for antimicrobial diffusion studies (disc diffusion susceptibility tests).

Precautions
Incubation in a carbon dioxide enriched atmosphere is not recommended because of its pH effect on the medium. If it is imperative to use CO₂ then known control organisms should be included with the test plates to measure its effect.
Carbohydrates should not be added to Mueller-Hinton Agar because they may influence the rate of growth of the organism and the resulting pH of the medium.
The addition of lysed horse blood to the medium may further reduce the levels of thymidine and prevent the growth of thymidine-dependent organisms.

The medium may not support the growth of some fastidious strains for example microorganisms that require thymine and thymidine for growth. Close adherence to the methodology is required to obtain satisfactory results.
