Predictive Modeling of Simultaneous Growth of Escherichia coli and Pseudomonas spp. in Inoculated Pork longissimus dorsi Muscle

doi:10.7506/spkx1002-6630-201317020

Abstract

Abstract:

Pork longissimus dorsi muscle was inoculated with both Escherichia coli and Pseudomonas spp., and then stored
at 10, 15, 20 ℃ or 25 ℃. The results showed that growth curves of E. coli and Pseudomonas spp. at different temperatures
could be well described by a modified Gompertz model. The influence of temperature on growth rate (μmax) and lag
phase (Lag) was well described by Belehradek model. The model developed in this study was confirmed to be reliable by
validation experiments at 13 ℃ and 22 ℃.

Key words: Escherichia coli, Pseudomonas, mixed strains, predictive modeling
