Yeast killer activity: a quantitative study

A method, based on the reaction of a sensitive strain being transferred to medium prefermented by a killer strain, is proposed for the quantitative determination of the "killer" activity in fermentation media by Saccharomyces cerevisiae K1. This technique enables killer activity to be clos...

More Information
Summary:A method, based on the reaction of a sensitive strain being transferred to medium prefermented by a killer strain, is proposed for the quantitative determination of the "killer" activity in fermentation media by Saccharomyces cerevisiae K1. This technique enables killer activity to be closely followed throughout the duration of batch fermentation. The killer activity in the culture medium is represented by the percentage decrease in viable biomass in comparison with the viable biomass of a reference culture.
