Identifikace mikroorganismů v kosmetických výrobcích s obsahem probiotik / Identification of microorganisms in cosmetic products with probiotics

Probiotics products are an integral part of the current market. Products containing probiotics cultures are also cosmetic products. The first part of the study focuses on testing of bacterial survival abilities in the environment of preservatives presented in cosmetic products. Collection strains of genus Lactobacillus were used for these tests. Another part of the study focuses on isolation of bacterial DNA from probiotic cosmetic products Ryor, Yoghurt of Bulgaria, FeminaMed and Lactovit Activit in PCR-ready quality. DNA was isolated by fenol extraction and with magnetic particles. Presence of bacteria was proved by genus and species specific PCRs Lactobacillus. Species specific PCR for identification of Lactobacillus pentosus was optimalized. Species identification was in accord with data declared by producers.
