Factor map of each individual of
the 68 psychrotrophic Bacillus cereus group
collection coming from pasteurized liquid
whole egg, according to their cytotoxic
activity (representative of the sanitary risk)
and their growth and egg spoilage potentials
at temperatures inferior or equal to 10°C
(representative of the spoilage risk). The
isolates located inside a dotted circle belong
to the same cluster, as determined by the
hierarchical cluster analysis performed after
PCA. For each cluster, two subgroups were
highlighted, indicated either with a black
symbol (main subgroup) or with a grey
symbol (secondary subgroup). The
percentages of variation explained by the
principal components (PC1 and PC2) are
indicated between brackets.
