Abstract
An improved powdered bacterial growth medium composition adapted to be admixed with water is described. The powdered growth medium includes an alkaline earth metal cation in a compound A admixed with a compound B containing an anion which reacts with the alkaline earth metal cation in compound A in an aqueous growth medium to form an essentially water insoluble salt or base, including the alkaline earth metal cation and the anion, which is acid neutralizing. The water insoluble salt is thus formed in situ in the aqueous growth medium when compounds A and B are added to the aqueous solution. Also described is an improved method for growing acid producing bacteria in an aqueous growth medium by forming the insoluble salt or base. The resulting growth medium is particularly adapted for neutralizing acids generated during growth of lactic acid producing bacteria which are grown for use in various food fermentations.
