FIG 5.

High-resolution snapshots of microbial population dynamics in untreated and treated pork sausage. (A) The total mesophilic APCs, psychrotrophic APCs, and lactic acid bacteria, and Enterobacteriaceae were enumerated from pork sausage containing 0, 3, 4, 5, and 6% LD. The log-transformed data from each treatment group are plotted from each of the 15-day time points taken over the 80-day refrigeration period, along with the standard deviations of the log-transformed data (whiskers). (B) The relative abundances of dominant taxa identified by pyrosequencing of 16S rRNA gene amplicons are plotted from paired samples taken at 15-day time points over the course of the 80-day shelf life (x axis) for the 3, 4, 5, and 6% LD treatments.
