The comparison of microbial ecology of nectarines and peaches
was realized by PCR-DGGE. For each type of fruit, the microbial
ecology was analyzed on four fruits and produced identical DGGE
patterns indicating a very high reproducibility (see samples 1e4
for each farming type in Figs. 1 and 2). Co-migrating bands as well
as overall pattern variations between samples were clearly visible
and further evaluated by Principal Component Analysis (PCA).
Nectarines and peaches replicates showed identical yeast and
bacterial rDNA DGGE patterns. Remarkably, the analysis of yeast
ecology showed variations between samples according to their
farming type (Figs. 3 and 4), but also according to their level of
freshness (cooperative vs. orchard, Fig. 4.2). Particularly, there is a
significant differentiation in between conventional fruits
compared to the fruit types (Fig. 4.1 and 4.2), with a pool of conventional
nectarines and conventional peaches for 90% or 80% of
similarity respectively.
