Abstract
Abstract The symbiotic interrelationship of probiotic bacteria and starter lactic acid bacteria is of fundamental importance in many fields of industrial microbiology and it is also a great interest of food technologists. This study deals with the antimicrobial potential of cell-free supernatants of Lactobacillus acidophilus NCFM, L. rhamnosus GG and Fresco culture when cultivated alone or together against 5 strains of Escherichia coli and 5 strains of Staphylococcus aureus. While the effect on E. coli was not proven (average change of final density compared to the control was only ΔNEC,24h = 0.12 log CFU ml-1), the decrease of S. aureus final density in the presence of nisin and cell-free supernatant of L. acidophilus NCFM and Fresco culture was considerable (ΔNSA,24h,nis10 = -1.95 log CFU ml-1 and ΔNSA,24h,NCFM+Fr24 = -0.69 log CFU ml-1, respectively).
