The microbial diversity of water kefir, made from a mixture of water, dried figs, a slice of lemon and sucrose was studied. The microbial consortia residing in the granules of three water kefirs of different origins were analyzed. A collection of 453 bacterial isolates was obtained on different selective/differential media. Bacterial isolates were grouped with randomly amplified polymorphic DNA...

Traditionally applied spontaneous fermentation was compared with the use of starter cultures to initiate fermentation after dry milling and sterilizing at 1210C for 10 minutes. Lactic acid bacteria (LAB) populations comprised 80% of the total viable bacteria and remained prominent throughout the fermentations, while number of moulds declined as the fermentation progressed. The fermentation meth...

BACKGROUND/AIMS Although probiotics have been extensively studied in irritable bowel syndrome, data on the impact of probiotics on chronic constipation are scarce. We aimed to evaluate the effects of kefir, which is a probiotic fermented milk product, on the symptoms, colonic transit, and bowel satisfaction scores of patients with chronic constipation. MATERIALS AND METHODS Twenty consecutive...

The aim of this study was to evaluate the potential of kefir production using cow-oat milk mixture. Therefore kefir samples with 20, 40 and 60 % of oat milk were produced. The effect of oat-milk ratio on physicochemical, rheological, microbiological and sensory characteristics of the kefir samples was studied during 21 days storage at refrigerated conditions. Increasing oat milk concentration a...

Kefir is one of milk products, produced by the addition bacteria and yeast-containing kefir starter. This study aimed to evaluate microbial characteristic, antibacterial activity, chemical physical characteristics, antioxidant organoleptic characteristic goat which treated with angkak (red yeast rice) extract supplementation during storage. The was initiated milling produce flour, then diluted ...

the potential of bulk starter fermentation strategy for production of a cost-effective and safe source of β-galactosidase was investigated. three different bulk starter media with different compositions were selected, and an industrial yogurt starter culture strain, l. bulgaricus dsm 20081 was cultivated in these media under ph-controlled conditions (ph=5.6) at 43°c. the media consisted of 1) b...

Kefir is a dairy beverage, obtained from lactic acid and alcoholic fermentation of its grains, which resembles yogurt in its flavour, aroma and consistency. It is composed of approximately 15-16 lactobacilli, approximately 7-9 streptococci/lactococci, 8 yeasts and 2 acetic bacteria (acetobacter). The fermenting action of Kefir bacteria and yeasts increases the biological value of milk, increasi...

Administration of kefir and a kefir cell-free fraction (KF) to mice injected with breast tumor cells produced, locally in the mammary gland, different profiles of cells secreting cytokines. Here, the immune cell populations in mammary glands affected by the cyclic consumption of kefir or KF for 2 or 7 d were evaluated using a breast tumor model. Apoptosis was also assayed as another mechanism i...

Received 24 April 2012; Accepted 7 November 2012 ABSTRACT: The “Encyclopedia of Fermented Fresh Milk” has classified Acidophilus and Bifidus milks as Non-traditional fermented milk products. These products contain Lactobacillus acidophilus and Bifidobacterium spp., respectively, that are known as probiotic microoganisms. In this study, some aspects of acidity development, pH measurement and bac...

The behaviour of Escherichia coli O157:H7 was studied during the manufacture and storage of Iranian white cheese in brine. Cheese was manufactured using pasteurized cow milk and inoculated with E. coli O157:H7 with inoculum level of 103 cfu/ml. Four treatments were designed. Cheeses were made with or without starter culture and kept immersed in 6 or 8% salt brine during ripening and storage. Ch...
