Total phenolic content of green teas ranged between 309-3915 mg GAE/L while in black teas they changed from 152 to 2089 mg GAE/L. The highest antioxidant activity was detected in green teas with 1942.761 μmol TE/L. Antimicrobial activity analysis showed that brewing the black teas at ratios of 200 and 100 mg/ml exhibited antimicrobial activity on P. aeruginosa while they did not show inhibitory effect on S. aureus and E. coli. However, all green tea concentrations exhibited antimicrobial effect on P. aeruginosa.}, number={1}
