Volatile organic compounds produced by Antarctic strains of Candida sake play a role in the control of postharvest pathogens of apples
Abstract
In this study the strategy of isolating psychrotrophic, non-pectinolytic yeasts able to grow in apple juice as potential biocontrol agents was a successful approach. Thirty-four yeasts isolated from Antarctic were able to maintain rot incidence caused by P. expansum and B. cinerea under 25% on apples stored at 0–1°C. Two of the isolates, identified as Candida sake, produced antifungal volatile organic compounds (VOCs) which inhibited the growth of five pathogens of apple (P. expansum, B. cinerea, A. alternata, A. tenuissima, and A. arborescens). This is the first report of VOCs produced by C. sake, as well as the first study of the inhibitory activity of VOCs produced by yeasts against species of Alternaria that cause postharvest apple rot.In vitro studies were performed on Apple Juice Agar at 0°C and 25°C due to the importance of evaluating antifungal activity in similar conditions to where the biocontrol agent are intended to be used. The VOCs produced by Candida sake strain 41E were also effective on in vivo assays to control P. expansum in Red Delicious apples.

VOCs released by C. sake reduced the incidence of apple rot caused by P. expansum and B. cinerea.
“Similarly, VOCs released by C. sake reduced the incidence of apple rot caused by P. expansum and B. cinerea (Arrarte et al. 2017).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
