Unmodified and low water activity (aw)-tolerant cells of Candida sake
CPA-1 applied before harvest were compared for ability to control blue
mold of apples (‘Golden Delicious’) caused by Penicillium expansum under
commercial storage conditions. The population dynamics of strain CPA-1
on apples were studied in the orchard and during storage following application of 3 × 106 CFU/ml of each treatment 2 days prior to harvest. In the
field, the population size of the unmodified treatment remained relatively
unchanged, while the population size of the low-aw–modified CPA-1 cells increased. During cold storage, the populations in both treatments increased from 103 to 105 CFU/g of apple after 30 days, and then declined
to about 2.5 × 104 CFU/g of apple. In laboratory studies, the low-aw–
tolerant cells provided significantly better disease control as compared
with the unmodified cells and reduced the number of infected wounds
and lesion size by 75 and 90%, respectively, as compared with the nontreated controls. After 4 months in cold storage, both unmodified and
low-a
w–tolerant cells of C. sake were equally effective against P. expansum on apple (>50% reduction in size of infected wounds)
