American Bacteriological Agar is a gelling agent used in the preparation of culture media and other bacteriological applications.
Agar is a natural hydrocolloid extracted from several species of red algae, mainly the Gelidium , Gracilaria and Pterocladia types. American Bacteriological Agar is a gelling agent used in the preparation of culture media and other bacteriological applications. The main advantage of this agar is the absence of inhibitors, which could interfere in the growth of microorganisms. It has excellent transparency, high hysteresis and very reliable reproducibility. Each batch produced is thoroughly tested for biological performance against a battery of known bacterial cultures in order to ensure proper growth characteristics and absence of inhibitors. American Agar type gives a lower strength than the European version. It is used in concentrations from 1 .2% to 1.6%.
