Abstract

Evaluate the antimicrobial properties of kombucha and its impact on the fermentation of mead obtained through mixed fermentation with Saccharomyces cerevisiae var. boulardii. Kombucha, a fermented beverage made from black or green tea (Camellia sinensis), is known for its beneficial microorganisms and bioactive compounds, which may exhibit antimicrobial effects. Thus, this study aims to determine whether the antimicrobial properties of kombucha are retained in the mead produced by the mixed fermentation of S. boulardii and kombucha. The research will be conducted over four months at the University of Lisbon and will involve the production of kombucha, mead, and subsequent antimicrobial tests. Kombucha will be prepared using organic green tea and fermented with a symbiotic culture of bacteria and yeast known as "symbiotic culture of bacteria and yeast" (SCOBY). Mead will be produced through co-fermentation with S. boulardii and kombucha, followed by antimicrobial tests to evaluate the effect on various pathogenic microorganisms. This study will contribute to the understanding of kombucha's potential to enhance the antimicrobial properties of mead and its applicability in the development of fermented products. The results will be integrated into ongoing research at the University of São Paulo and FAPESP, with implications for food biotechnology, food microbiology, and the potential for antimicrobials.
