Pearson correlation analysis among these bacteria including
both pathogens and lactobacillus was performed to better understand
their relationships. Tables 1 and 2 show the correlation matrixes
of survival and growth of bacteria (in broth and milk) without
and with 10% blackberry juice, respectively. After addition of
blackberry juice, the correlation coefficients were significant among
the three pathogens or three Lactobacillus species, but there was no
statistically significant correlation between species of pathogens
and species of Lactobacillus (P > 0.05). In control groups (without
addition of blackberry juice), however, all correlation groups except
between L. plantarum and E. coli O157:H7, and between L. plantarum
and L. rhamnosus had significant correlation coefficients.
