Abstract:		"This work aimed to evaluate the performance of co-cultivation of potential probiotic yeast and lactic acid bacteria (LAB) in producing plant-based fermented beverages. The co-culture comprised LAB Lactiplantibacillus plantarum CCMA0743 with the yeasts Pichia kluyveri CCMA 0615, Pichia guilliermondii CCMA 1753 and Debaryomyces hansenii CCMA 1761 separately. The plant substrate was 75 g oat, 175 g sunflower seeds, and 75 g almonds. The viability of microorganisms in the plant-based matrix was evaluated during fermentation, storage at 4 degrees C, and under simulated gastrointestinal tract (GIT) conditions. Chemical analysis, antioxidant activity, and sensory profile of the beverages were also determined. The three yeasts and the LAB showed counts greater than 6.0 log CFU/mL after fermentation, and the plant-based matrix protected the yeasts during simulated digestion. P. kluyveri and D. hansenii showed higher survival than P. guilliermondii and L. plantarum after exposure to simulated GIT conditions. The pH of the plant-based matrix reduced from approximately 7 to 3.8. Lactic acid was the main organic acid produced during fermentation. In addition, 113 volatile compounds were detected by gas chromatography-mass spectrometry (GC-MS), including alcohols, aldehydes, alkanes, alkenes, acids, ester, ether, ketones, phenol, and amides. The beverage sensory profile varied with the co-culture. The co-culture D. hansenii and L. plantarum showed higher antioxidant activity than the other co-culture tested, and the homogeneous texture attribute characterized the beverage produced with this combination. Results show the suitability of tested co-cultures to produce a plant-based fermented beverage and indicate more significant potential for D. hansenii and L. plantarum co-culture as a starter for its functionalization"
