Биохимическая активность культур молочнокислых бактерий, перспективных для использования при изготовлении сыров с пониженным содержанием жира

В статье приведены результаты исследований липолитической и протеолитической активностей при разных условиях культивирования 27 штаммов лактобацилл, а также данные о способности продуцировать экзополисахариды. Свойства микроорганизмов являются определяющими биохимическими факторами в процессе созревания сыра с пониженным содержанием жира, для формирования органолептических характеристик продукта. Результаты экспериментов показали, что штаммы имеют штаммоспецифическую активность протеаз при инкубировании их при оптимальных и низких температурных режимах, при этом для большинства штаммов при снижении температуры культивирования наблюдается уменьшение протеолитической активности. Выявлено отсутствие липолитической активности у исследованных штаммов. Для отдельных штаммов обнаружена способность продуцировать экзополисахариды.
