A quote from the following paper...
"Certain lactobacilli have been shown to produce inhibitory products against other organisms normally considered as objectionable in foods.The inhibitory compound that accumulated in the culture and in the cell suspensions was identified as hydrogen peroxide. In our study it was shown that even at refrigeration and low pH temperature, lactobacilli isolated from yogurt produced hydrogen peroxide."
