Fig. 3From: The occurrence of Listeria monocytogenes is associated with built environment microbiota in three tree fruit processing facilitiesRarefaction curves for 16S rRNA V4 (a) and ITS2 (b) sequences. Individual samples were plotted using the number of OTUs that represent the sequence sample size on x axis and the number of unique OTUs that indicate the species richness on y axis. Each curve is color-coded based on the facility in which the sample was collectedBack to article page
