Identification of probiotic bacteria in complex food matrices and dietary supplements

Theoretical part of the thesis deals with the general characteristics of probiotic bacteria, their effect on human health and with technological demands imposed on them. Furthermore the thesis deals with actual methods of bacterial identification, especially on the base of polymerase chain reaction. Presence of the declared probiotic bacteria was analysed with the polymerase chain reaction (PCR) and the DNA was isolated from the sample of food additive with the use of magnetic particles
