Предлагаемый новый штамм Enterococcus durans ВКПМ В-13058, выделенный из толстого отдела кишечника подсосного теленка в РСО-Алания, хорошо приспособлен к местным условиям. Неприхотлив в культивировании и хранении, обладает низкой предельной кислотностью и высокой скоростью свертывания молока, что позволяет повысить экономическую эффективность при производстве (за счет ускорения производственного процесса и увеличения срока годности готовой продукции).The proposed new strain of Enterococcus durans VKPM B-13058, isolated from the large intestine portion of the suckling calf in RNO-Alania, is well adapted to local conditions. It is unpretentious in cultivation and storage, it has low limiting acidity and high speed of coagulation of milk, which allows to increase economic efficiency in production (due to the acceleration of the production process and increase the shelf life of the finished product).
Штамм проявляет высокую антагонистическую способность по отношению к условно-патогенной и патогенной микрофлоре.The strain exhibits a high antagonistic ability against opportunistic and pathogenic microflora.
Предлагаемый новый штамм лактобактерий Enterococcus durans ВКПМ В-13058 обладает высокой биологической активностью и является основой для получения кисломолочных напитков.The proposed new strain of lactobacilli Enterococcus durans VKPM B-13058 has a high biological activity and is the basis for the production of fermented milk drinks.
