1. Improving composition and microbiological characteristics of milk kefir using colostrum
Abstract Kefir characteristics are influenced by raw materials. Fresh milk and colostrum have different characteristics. In this research, colostrum was used as additional material in kefir production which could affect the chemical, microbiological, and antimicrobial properties of final the product. This study was aimed to investigate the chemical and micro

6. Survival of Escherichia coli O157:H7 and Staphylococcus aureus during the fermentation and storage of kefir
Abstract The survival of Escherichia coli O157: H7 and Staphylococcus aureus, which are foodborne pathogens was investigated during fermentation and storage of kefir. The kefir grains were inoculated with 5% of the whole fat UHT cow milk and the E. coli O157: H7 and S. aureus cultures were added separately to give 105 cfu mL-1 and left to incubate at 22 °C

9. Evaluation of antagonistic activity of milk fermented with kefir grains of different origins
In this study, the potential of kefir grains, obtained from three different towns/cities in the Southeast Region of Brazil to inhibit the growth of the five pathogenic microorganisms was evaluated. The samples showed the growth inhibition from 42.80-69.15 for Staphylococcus aureus ATCC 6538, 30.73-59.89 for Escherichia coli ATCC 11229, 44.99-73.05 for Salmon
