Assessment and comparison of the antimicrobital activity and antioxidant potential of commercially available probiotic infused green tea, slim tea and green coffee

Abstract

Aim : The aim of the study is to assess and compare the antimicrobial and antioxidant activity of commercially available probiotic infused green tea, green coffee and slim tea. Materials and methods: Synthesis of probiotic medium is done by 2 gm of each sample was taken in 1 flask of 15 ml peptone water and mixed well. Then it is inoculated in MRS agar plate and it is sealed in an anaerobic jar for 48 hours. Antimicrobial activity is tested by agar well diffusion method against S.mutans and the zone of inhibition is measured. Antioxidant activity is measured with DPPH and % of inhibition is measured. Results : In the antimicrobial activity, in all the samples the activity increased with increasing concentration, but the maximum was seen in slim tea. In antioxidant activity, all the samples showed antioxidant activity although green tea showed more antioxidant activity than green coffee and slim tea. Conclusion: In our study, Bacillus coagulans incorporated green tea, green coffee and slim tea exhibited both antimicrobial and antioxidant properties.
