Tea, one of the most common beverages, originates from the leaves of the Camellia sinensis plant. Two major groups of tea are fermented black tea and unfermented green tea.

In this study, the antibacterial effects of TF and pEGCG were evaluated against six selected bacteria, Staphylococcus epidermidis, Streptococcus mutans, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa and Proteus vulgaris, using an antibacterial assay. A viability assay using SYTOX® staining and flow cytometry was also used to determine the effect of these compounds …
