Figure 4. Composition of fermentation microbiota in binary strain competitions of strains of L. reuteri.

Figure 4

Sourdoughs were inoculated with L. reuteri LTH2584 and 100-23 (Panels A and B) or with L. reuteri LTH2584 and LTH5448 (Panels C and D) and maintained by continuous back-slopping with 10% inoculum over 10 fermentation cycles with 1 d incubation times. Sourdough microbiota were analysed by differential plate counts (Panels A and C) and results were expressed as log proportion of the individual strains to the total viable cell counts. Sourdoughs were also analysed by qPCR targeting strain-specific sequences and log DNA copy numbers converted to cell counts using the strain-specific calibration curves (Panels B and D). Results were expressed as proportion of the individual strains to the total cell counts. Symbols represent L. reuteri strains LTH2584 (◼), LTH5448 (□) and 100-23 (◯).
