The population of coliform organisms decreased (P＜0.05) when subjects were in the period of fermented soy milk consumption.CONCLUSION: Intake of fermented soy milk significantly improved the ecosystem of the intestinal tract in the body by increasing the amount of probiotics.展开更多

The camel milk plays a vital role in the food of the Algerian nomads in the Sahara. During February and September, 20 samples of the raw camel＇s milk were taken starting from different livestock of camels from three different Sahariennes regions （Bechar, EI-Bayadh and Naama）. These 20 collected samples were analyzed by physico-chemical and microbiological methods. The results of physicochemical analyze obtained from two hot and cold seasons are respectively the following： T ~C （35.83 and 33.95）, pH （6.36 and 6.49）, density （1.031 and 1.032）, dornic acidity （18.6 and 18.3 ~D）, dry matter （93.4 and 144.8 g/L）, fat contents （30 and 52.1 g/L）, total protein （26.3 and 33.1 g/L） and ashes （7.46 and 8.66 g/L）. The protein profile obtained by electrophoretic analysis （SDS-PAGE） showed that camel milk contains several types of proteins and some have a molecular weight identical to major proteins of the cow＇s milk. The final results showed that camel milk has generally a comparable composition to that of bovine milk. The microbiological analysis, of these samples, detected a significant number of the total microflora, Staphylococcus aureus and total coliforms. The absence of Clostridium and fecal coliforms was observed. Several species of lactic acid bacteria were detected such as Lactococcus lactis subsp, lactis, Lactococcus lactis subsp, lactis biovar, diacetylactis, Weissella cibaria and Enteroccocusfeacalis.展开更多

The traditional Russian type kefir was used as control. The various germ groups and pH values were determined in wk 2, 4 and 6.RESULTS： The number of all microbes increased during the 4-week probiotic treatment. The number of microbes increased 4,3-fold in the control group and 6.8-fold in Biofir-treated group. The probiotic kefir caused multiplication of the probiotic flora, meanwhile the undesired bacteria multiplied in the control group. No significant change of pH values of the faeces was found in both groups.CONCLUSION： The Hungarian probiotic keflr （Biofir） is capable of promoting multiplication of probiotic bacterial flora in the large bowel.展开更多
