Foods fermented by <i<Lactobacillus</i< with probiotic properties convey health benefits to consumers, in addition to fulfilling the basic function of nourishing. This work aimed to evaluate the growth characteristics of <i<L. gasseri</i< in passion fruit juice and passion fruit added with green tea. Fermentation under evaluation of different pH (3.5–7.5), temperature (30–44 °C), and with the addition of green tea (7.5–15%), took place for 48 h. The results showed that a pH of 7.5 and temperature of 44 °C showed higher cell production, and it was also verified that the addition of 15% of green tea induced the growth of <i<L. gasseri</i< in passion fruit juice. The concentrations of probiotic cells observed were above 9 Log CFU.mL<sup<−1</sup< and, therefore, they are promising products for consumption as a functional food and application in the food industry with potential health benefits.
