Yeast makes bread, beer
Lactobacillus makes bacteria, yoghurt
Fermentation in Lactobacillus
Lactose —> lactic acid
Sterilisation can happen if heated as well as using anti-bacteria. It removes the microbe which reduces contamination so we do not get infected.
Pasteurisation kills the bacteria which reduces contamination so we do not get infected. Also, this makes sure that the right product is produced.
Lactobacillus undergoes fermentation. pH lowers which denatures the protein
