“…It is essential to milk fermentation, especially in the yoghurt and cheese making processes, to provide optimal conditions for the development of texture and flavour (Zoon & Allersma, 1996). In addition, S. salivarius or some lactic acid bacteria has the great potential use as a starter in the production of Gamma-aminobutyric acid (GABA)-containing yoghurt, fermented milk, cheese and other functional fermented foods (Irigoyen, Ortigosa, Juansaras, Oneca, & Torre, 2007;Lee et al, 2010;Minervini, Bilancia, Siragusa, Gobbetti, & Caponio, 2009;Nomura, Kimoto, Someya, Furukawa, & Suzuki, 1998;Park & Oh, 2007;Yang et al, 2008). E. faecalis was isolated from various fermented foods such as Tunisian fermented dough, dairy products, fermented capers, vegetable foods and fermented milk (Burgos, López, Abriouel, Omar, & Gálvez, 2009;Cariolato, Andrighetto, & Lombardi, 2008;Gardini et al, 2008;M'hir et al, 2008;McGowan-Spicer et al, 2008;Pérez-Pulido et al, 2006).…”
