Effect of Biotechnology Method of Fermented Kombucha Flower Telang (Clitoria ternatea) As Antibacterial Acne vulgris

Abstract

Telang flower kombucha fermented is one of the probiotic drinks that is cultured through a consortium of bacteria and yeast made from telang flower. Research on telang flower kombucha fermentation is one of the latest breakthroughs that needs to be applied as a basic illustration in the field of applied science which is progressing very rapidly to continuously improve its technology. This study aims to provide scientific information about the antibacterial activity of a fermented kombucha of telang flower from each concentration of sugar solution used. The concentration of the sugar solution used in this study was 20%, 30%, and 40%. Each treatment was repeated three times. The positive control was kombucha made from black tea. Negative control in the form of sterile distilled water. The well diffusion method is one of the methods used in antibacterial testing by calculating the diameter of the inhibition zone. Telang flower kombucha which has been fermented by a consortium of bacteria and yeast has antibacterial activity as Propinobacterium acne at a sugar concentration of 40% with an average inhibition zone diameter of 12.46 mm in a strong category, so that apart from being a functional probiotic drink, it has the potential as an active ingredient. cosmetics such as creams, serums, facial soaps, and facial sprays
