BACTERIAL AND YEAST BY-PRODUCTS FORMATION IN ETHANOL FERMENTATION OF GLUCOSE MEDIUM AND RYE MASHES

Zymomonas mobilis - bacterium producing ethanol and Saccharomyces cerevisiae yeast were compared for their fusels and other by-products biosynthesis during classical ethanol fermentation and when immobilized in agar gel. Glucose medium as well as classical and extruded rye mash were used. The most intensive production of fusels took place in the first 12 h of fermentation. When the microorganisms were immobilized in Ca-alginate, they produced more higher alcohols then during classical fermentation. The amount of by-products produced on glucose medium was higher than that produced on rye medium. Spirits prepared from yeast fermentation contained 7 times more by-products than those made from bacteria fermentation.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN.
