Zusammenfassung
Die verschiedene caseinolytische Aktivität ist von dem Nachweismedium abhängig. Dieβ-Casein-Aktivität der Kultur war in jedem Fall größer als die Aktivität der anderen Casein-Fraktionen. Die höchste Aktivität wurde beim Wachstum in einem Casein-Nährboden mit 0,1% Hefeextrakt, 20 mmol CaCl2 und 1% Lactose gefunden. Der Einfluß des Nährbodens auf die proteolytische Aktivität der untersuchten Keime wurde ebenfalls ermittelt.
Summary
Different caseinolytic activity levels ofLactococcus lactis subsp.lactis IFPL 367 were obtained depending upon the culture medium tested. Activity on theβ-casein fraction was in all cases higher than activity on other casein fractions. The highest activity level was recorded for bacterial cells cultured in a casein-based medium that also contained 0.1% yeast extract, 20 mmol/CaCl2, and 1% lactose. The effect of the components of the growth media on the proteolytic activity of the bacterial strain employed in the experiment is also discussed.
