Growth and Activity of Selected Probiotic Strains in UHT Milk
ABSTRACT: The growth rate of two probiotic strains with documented health effects was studied in ultra-high temperature treated milk separately and beside each other. The probiotic strains were Lactobacillus acidophilus (La-5) and Bifidobacterium lactis (Bb-12). Fermentation was followed for 12 h at 37 ˚C and the samples were analyzed for pH, titratable acidity and viable counts of probiotic ba...
متن کاملPrevalence of Virulence Factors and Antimicrobial Resistance of Streptococcus agalactiae and Streptococcus uberis in Ruminant Sub-clinical Mastitic Milk in Iran
Background and Aims: The aim of this study was to determine the virulence and antibiotic resistance properties of Streptococcus agalactiae (S. agalactiae) and Streptococcus uberis (S. uberis) isolated from the ruminant’s sub-clinical mastitic milk in Iran. Materials and Methods: Positive samples in the CMT test were cultured and S. agalactiae and S. uberis have been identified using bi...
متن کاملActivation of bovine plasminogen by Streptococcus uberis.
Culture filtrate from Streptococcus uberis was found to activate bovine and equine plasminogen but not that from rabbit, human or porcine plasma. In contrast, streptokinase from a Lancefield group C Streptococcus activated human plasminogen but not that from bovine, porcine and rabbit plasma. Very slight activity was observed against equine plasminogen. Plasmin was detected by hydrolysis of ski...

متن کاملColor Changes of UHT Milk During Storage
In this study measurements of color parameters of UHT milk were performed, by using a MOM-color 100 photoelectric tristimulus colorimeter. Colors of UHT milk samples containing 3.2% and 1.6% milk fat, processed under industrial conditions, packed in polyethylene terephtalate (PET) based packages, and stored for 0, 15, 30, 45, 60 and 90 days at ambient temperature (20±5°C) were examined. Results...
