Pichia angusta is an effective biocontrol yeast against postharvest decay of apple fruit caused by Botrytis cinerea and Monilia fructicola
Open accessAbstract
The efficacy of eight isolates of Pichia angusta against three common postharvest pathogens of apple fruit was evaluated for the first time. All tested strains showed significant biocontrol activity against both Botrytis cinerea and Monilia fructicola, whereas efficacy against Penicillium expansum was poor. A leucine-auxotrophic mutant had no significant biocontrol activity against brown rot of apple, while the addition of 0.6-1.2 g L(-1) leucine in the fruit wound fully restored the biocontrol activity of this mutant against M. fructicola. Given the extremely well-developed classical and molecular genetics, the availability of genomic libraries, and its complete genomic sequence, this species can serve to elucidate the mechanisms related to biocontrol capacity.

In Pichia (Ogataea) angusta, the wild-type strain reduced brown rot lesion caused by Monilinia fructicola on apple fruit, while its leucine-auxotrophic mutant L1 had no significant effect in controlling the pathogen.
“while the wild-type strain proved effective in reducing brown rot lesion caused by Monilinia fructicola on apple fruit, its derivate leucine-auxotrophic mutant L1 had no significant effect in controlling the pathogen.”

The addition of exogenous leucine fully restored the biocontrol capability of P. angusta mutant L1, whereas a leucine stand-alone treatment showed no significant biocontrol effect.

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.
