STUDY OF THE LEVEL OF ORGANIC ACID BIOSYNTHESIS BY PROPIONIC ACID BACTERIA CULTURES
Abstract
The article presents data on the reduction of the acidity of the nutrient medium by cultures of propionic acid bacteria. The period of maximum acid production relative to the increase in the optical density of the medium was determined. The profile of carbon source utilization by propionic acid bacteria cultures was also established and was shown to include a broad range of mono- and disaccharides, as well as the trisaccharide raffinose and polyhydric alcohols. The concentrations of organic acids after cultivation in a medium based on the fugate of homofermentative lactic acid bacteria containing lactic acid were determined: formic acid, 1.5–5.9 g/L; lactic acid, 0.2–4.9 g/L; acetic acid, 0.1–4.0 g/L; succinic acid, 0.4–2.9 g/L; propionic acid, 3.2–10.3 g/L. A decrease in lactic acid content by 0.3–28.6 g/L was also observed.
