The aim of this research was to observe the combined usability of Enterococcus faecium and Enterococcus durans strains, which are resistant to adverse environmental conditions, together with commercial probiotic starters in the production of probiotic fermented milk. Accordingly, eight different probiotic fermented milks were produced; AF:Lactobacillus acidophilus + Enterococcus faecium, BF:Bifidobacterium animalis subsp. lactis + Enterococcus faecium, CF:Lactobacillus casei + Enterococcus faecium, RF:Lactobacillus rhamnosus + Enterococcus faecium, AD:Lactobacillus acidophilus + Enterococcus durans, BD:Bifidobacterium animalis subsp. lactis + Enterococcus durans, CD:Lactobacillus casei + Enterococcus durans, RD:Lactobacillus rhamnosus + Enterococcus durans. As a result of the data obtained in the study, it was found that fermented dairy products containing Enterococcus faecium and Enterococcus durans had no negative effects on the physicochemical, rheological properties and probiotic viability, and positively affected the sensory properties of the samples. The viscosity and hardness values of probiotic fermented milk produced by combining with E. durans were higher than by combining with E. faecium and serum separation was not occurred. Also, probiotic bacteria viability was higher than 7 log cfu/ml level at the end of the storage period.

含有粪肠球菌和杜伦肠球菌菌株的发酵乳的一些理化，流变，感官特性和益生菌活力的分析

本研究的目的是观察在不利的环境条件下具有抵抗力的粪肠球菌和杜伦肠球菌菌株的组合可用性，以及商业化的益生菌发酵剂在益生菌发酵乳生产中的可用性。因此，产生了八种不同的益生菌发酵乳。AF：嗜酸乳杆菌 + 粪肠球菌，BF：动物双歧杆菌亚种。乳酸 + 粪肠球菌，CF：干酪乳杆菌 + 粪肠球菌，RF：鼠李糖乳杆菌 + 粪肠球菌，AD：嗜酸乳杆菌 + 杜伦肠球菌，BD：动物双歧杆菌亚种。乳酸 + 杜伦肠球菌，CD：干酪乳杆菌 + 杜伦肠球菌，RD：鼠李糖乳杆菌 + 杜伦肠球菌。根据研究获得的数据，发现含有粪肠球菌和杜伦肠球菌的发酵乳制品对理化，流变性质和益生菌活力没有负面影响，并积极影响样品的感官特性。与杜兰肠球菌联合生产的益生菌发酵乳的粘度和硬度值高于与粪肠球菌联合产生的益生菌发酵乳，并且没有发生血清分离。另外，在储存期结束时，益生菌的生存力高于7 log cfu / ml。
