DIFFERENT TEMPERATURES SELECT DISTINCTIVE ACETIC ACID BACTERIA SPECIES AND PROMOTES ORGANIC ACIDS PRODUCTION DURING KOMBUCHA TEA FERMENTATION

By Francesca De Filippis, Antonio Dario Troise, Paola Vitaglione, Danilo Ercolini

Kombucha is a traditional beverage produced by tea fermentation, carried out by a symbiotic consortium of bacteria and yeasts. Acetic Acid Bacteria (AAB) usually dominate the bacterial community of Kombucha, driving the fermentative process. The consumption of this beverage was often associated ...

L-LACTIC, L-ASCORBIC, TOTAL AND VOLATILE ACIDS CONTENTS IN DIETETIC KOMBUCHA BEVERAGE

By Radomir V. Malbaa, Eva S. Lonar, Ljiljana A. Kolarov

Kombucha or tea fungus is a symbiosis of osmophilic yeasts and acetic acid bacteria. After about 7 days, this symbiosis converts a very simple substrate, sucrose, and black tea, in a slightly carbonated, acidic, refreshing beverage with high pharmaceutical and nutritional value. Inulin is a ...
