Selection of Pichia onychis isolate for biological control of Botrytis cinerea based on its eco-physiological characteristics Academic Article uri icon

Resumen

  • The effect of physiological parameters on growth, adherence to leaflets surface, tolerance to UV radiation and biocontrol of indigenous antagonist yeasts Pichia onychis (Lv027, Lv031. Lv297, Lv298, Lv299), Pichia anomala (Lv050) and Candida oleophila (Lv314) was studied. All isolates showed higher growth in culture media with acid pH (3 to 6) than the growth in basic pH conditions (≥ 8). All P. onychis isolates exhibited high tolerance stress conditions. Isolates Lv297 and Lv314 presented high adherence to foliar surface and isolates Lv297 and Lv050 gave effective control of B. cinerea. The fact that P. onychis Lv027 is effective biocontrol agent and tolerate a wide range of growth and stress conditions makes it an excellent candidate for production and field evaluation.
