Lactobacillus pentosus and Pichia membranifaciens were used as starters in black olive fermentation.
Their in situ imposition on olives was studied in order to form biofilms.
L. pentosus could dominate the process and recovered 100% at the end of fermentation.
P. membranifaciens was recovered in the middle but not in the end of the process.
L. pentosus could be used as a multifunctional starter in black olive fermentation.
