Abstract
The paper investigates effects of pectolytic enzyme treatments on red grape mashes on the microbiological quality of wines and wine stability with counting of the presence yeast cells (Saccharomyces cerevisiae), after incubation on Sabourald-maltose agar. Also wine samples were investigates of the presence moulds and other bacteria, as and dangerous bacteria Salmonella and Shigella, Staphylococus aureus, Proteus spp., Sulphite-reducing clostridy and Escherichia coli.
In all wine samples the results showed that have yeasts Saccharomyces cerevisiae. Saccharomyces is not regard as spoilage organism only if it is found in the wrong place at the wrong time (e.g. in a bottle of semi-sweet wine) causing re-fermentation, meanwhile the better is to have less. Pectinolytic enzyme preparation Trenolin Rot DF showed the best results.
