Abstract
The antimicrobial activity of Bifidobacterium bifidum and Bifidobacterium lactis against some pathogenic bacteria such as Staphylococcus aureus, E. coli and Salmonella typhimurium was investigated during the manufacture and preservation of four types of yoghurt Traditional yoghurt (TY) (Starter culture), Bifidobifidium yoghurt (BY) (Starter culture + Bifidobacterium bifidum), Bifidolactis yoghurt (LY) (Starter culture + Bifidobacterium lactis) and Mixed yoghurt (MY) (Starter culture + Bifidobacterium bifidum+ Bifidobacterium lactis). Traditional yoghurt, Bifidobifidium yoghurt, Bifidolactis yoghurt and Mixed yoghurt samples were inoculated with 104 cfu/g Staphylococcus aureus, E. coli and Salmonella typhimurium and preserved for 14 days at 4±1oC. The inoculated bacterial count and the titratable acidity were determined in the prepared yoghurt samples at zero, 3rd, 5th, 7th and 14th day of cold storage. The obtained results revealed elevation in the titratable acidity and noticeable inhibition in the count of the inoculated bacteria during the storage period of prepared yoghurt samples at 4±1oC.
