STUDYING THE INFLUENCE OF ALOE VERA ON THE GROWTH OF THE LACTOBACILLUS ACIDOPHILUS AND BIFIDOBACTERIUM BIFIDUM PROBIOTIC BACTERIAS IN PRODUCING PROBIOTIC MILK AND YOGHURT

Probiotic is a Latin term which means for life (life-giving). Probiotics are usually one or a mixture of microorganisms which consist of
useful bacterias and yeasts. If consumed by humans or animals, Probiotics can have various useful benefits through improving the
host’s digestion microflora features. To determine the influence of various dozes Aloe Vera on the growth of Lactobacillus
acidophilus and Bifidobacterium Bifidum probiotic bacterias in the first (milk) and second (yoghurt) probiotic stage, 0.33 gram of
Lactobacillus acidophilus and Bifidobacterium Bifidum Lyophilized bacteria were added separately to 1 liter of low-fat milk, and the
samples were studied based on their PH and their acidity during incubation and persistence (21 days) time. Observations indicated that
3% Aloe Vera probiotic milk and yoghurt with Bifidobacterium Bifidum and 2% probiotic milk and 3% Aloe Vera yoghurt in the
sample which contained Lactobacillus acidophilus yielded acidity much faster than other samples. Thus, it may be concluded that
increasing the density of Aloe Vera has a positive influence on the growth of Lactobacillus acidophilus and Bifidobacterium Bifidum
bacteria in probiotic milk and yoghurt
