THE APPLICATION OF IMMOBILIZED BIOCATALYZERS TO INTESNIFY THE ETHANOL FERMENTATION OF LACTOSE.

Ethanol fermentation of lactose mash by biocatalyzers immobilized in calcium alginate was studied in order to improve the process productivity and economy. The fermentation effectiveness of S. cerevisiae co-immobilized with a β-galactosidase and the directly lactose- fermenting immobilized yeast: K. fragilis and C. pseudotropicalis were compared. The application of the immobilized K. fragilis produced desirable results and even after its 10th (20 days) fermentation the immobilized yeast provided the stable high fermentation level (on average about 6 %/vol of ethanol) while maintaining its activity. Such lactose-mash fermentation was greater than in conventional method (by free cells). In addition, the application of S.cerevisiae co-immobilized with β-galactosidase produced somewhat greater fermentation levels than the conventional method.

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. The program aims at improving the level of publishing and editing practices, increasing the impact of scientific journals on science development, and extending the international range of scientific journals.
