Bacteriological agar is a gelling agent used in the preparation of culture media and in other routine bacteriological applications. Its main advantage is the absence of inhibitors which could hinder optimal development of microorganisms. In addition, bacteriological agar also possesses other attributes such as high transparency, high hysteresis and very reliable reproducibility. Bacteriological agar American type gives lower gel strength and is utilized at concentrations ranging from 1.2% to 1.6%. Each batch is thoroughly tested for biological performance against a battery of known bacterial cultures in order to ensure proper growth characteristics and absence of inhibitors. Also, other tests are carried out to be certain that each batch meets established physical and chemical specifications.
