Yeast Mixtures for Postharvest Biocontrol of Diverse Fungal Rots on Citrus limon var Eureka

Mexico is among the most important citrus fruit producers in world. However, during storage, several problems related to fungi can arise. The common fungal postharvest diseases detected on Citrus limon var Eureka (Italian lime) produced Tamaulipas state are green/blue mold (Penicillium spp.), fusarium rot (F. oxysporum, F. solani, proliferatum, others), and anthracnose (Colletotrichum spp.). In this work, we selected yeasts, occurring as natural epiphytic mycoflora of lemons or from fermented traditional products, be tested part a formulation for protecting stored against diseases. best-performing labeled LCBG-03 (Meyerozyma guilliermondii), LCBG-30 (Pseudozyma sp.), LCBG-49 (Saccharomyces cerevisiae), were test their compatibility biocontrol performance strains Penicillium digitatum (AL-38), Fusarium sp. (AL-21), Colletotrichum gloeosporioides (AL-13), Epicoccum sorghinum (H3A). Based vitro regarding percentage radial growth inhibition, both applied individually two yeasts mixed at equal cellular concentrations, best combinations (containing M. guilliermondii formulated with either Pseudozyma S. cerevisiae) efficacies higher than 95% rate inhibition lemon fruits. This work contributes search compatible yeast aim diminish losses fruits using protection.
