Abstract: Probiotics are bacteria of natural human microbiota which have positive effect on the host organism physiology. Probiotic strains which are selected from wild strains have to possess certain qualities such as: being competitive against pathogens, synthesizing appropriate metabolic products and ability to adhere. Probiotic strains also have to show properties which allow them to be safe to use as well as render them resistant to conditions occurring during production processes and in human gastrointestinal tract. Inversely – the production processes used in the preparation of probiotics, have to be adjusted to maintain acceptable survival rates of bacteria. Pharmabiotics are a particular kind of probiotics, modified using genetic engineering to achieve desirable traits, either functional or technological.
