Polyvinylpyrrolidon als Schutzstoff bei der Untersuchung gerbstoffgehemmter Enzymreaktionen

摘要

Investigations on various enzyme systems showed that addition of polyvinylpyrrolidone protected enzymatic reactions against inhibition by tannins. Furthermore, polyvinylpyrrolidone reactivated enzymatic reactions already inhibited by tannins. Addition of polyvinylpyrrolidone during the isolation of enzymes from tannin containing tissues prevented inhibition by tannins.
