Description
Bacto™ Casamino Acids is an acid hydrolysate of casein, prepared according to the method
described by Mueller and Miller.1 The method described, reduces the sodium chloride and iron
content of the hydrolyzed casein. This hydrolyzed casein, supplemented with inorganic salts,
growth factors, cystine, maltose and an optimum amount of iron was used by Mueller and
Miller to prepare diptheria toxin. Bacto Casamino Acids duplicate this specially treated
hydrolyzed casein.
