Research on the possibility of propionic acid fermentation in milk permeate was carried out by the authors. On the base of fermentation experiments with liquid media-models and on milk permeate they have arrived at the following conclusions. Regulation of pH-value in fermentative liquid improves propionic acid production significantly. By using mixed strain culture of Lactobacillus Propionic acid bacteria time of fermentation can considerably be reduced. Propionic acid production has a maximum at 40 g/m3 lactose content and in thi case production of propionic acid on a level of 21,3 g/dm3 means achieving 97 per cent of the theoretical maximum value.
