Effect of Hydrogen Peroxide on Activity of Lactic Cultures in Milk

Abstract
The ability of single strain lactic streptococci and commercial lactic starter cultures to produce acid was evaluated in milk containing 0-200 [mu]g of hydrogen peroxide (H2O2) ml. All cultures were inhibited slightly at H2O2 concentrations as low as 5 ug/ml. Both single strain and commercial cultures varied in their sensitivity to H2O2.
