As presented in Fig. 2, the counts of yeast of all the samples significantly decreased during the course of fermentation. Yeast counts gradually decreased to below detectable level at the end of fermentation when 7 log CFU/g of L. sakei C2 were inoculated. However, yeast counts still were respectively 2.0 and 2.6 log CFU/g in the samples inoculated with 5 log CFU/g of L. sakei C2 and the natural fermentation. During the course of fermentation, total
