Electrode Potential Measurements of Fermenting Sauerkraut as Influenced by <i>Aerobacter cloacae</i>

TL;DRAbstract

The medium which supports bacterial growth exerts a governing influence on the rate and extent of bac- terial growth.Where the growth of lactic acid bacteria is favored by the presence of acid, other bacteria are unfavorably affected.This fact is of importance in the sauerkraut fermentation where the formation of acid soon retards the growth of spoilage type organisms.Another factor which influences the growth of bacteria is the oxidation-reduction potential of the medium (Allyn and Baldwin, 1923).The initial oxidationreduction potential of the medium exerts a governing influence on the growth of bacteria when adverse states of oxidation exist within the bacterial environment.This action may be selective at times, since some bacteria grow more favorably than others at lower oxidation-reduction potentials.It is a general phenomenon that growing bacteria lower the oxidation-reduction potential.The lowering of the potential by one of two organisms in mixed culture may result in a relation
