Apple Pomace Microbiome Carrying Fungal Load against Phytopathogens – Considerations Regarding Application in Agriculture and Horticulture

Karolina Oszust, Magdalena Frąc


This experiment evaluated the taxonomic diversity of the fungal community in conventional (AP) and organic (OAP) apple pomace using high-throughput sequencing, applying fungal genetic barcodes to functional guilds. The most abundant taxonomic groups identified in both AP and OAP were the genera Aureobasidium, Cladosporium, and Alternaria, classified into the pathotroph-saprotroph-symbiotroph guild. The phenotype microarray provided insight into the role of the apple pomace fungal community in the ecosystem. It is theorized that adding apple pomace to the soil may improve the bioavailability of bioresource-based polyols. Evaluation of the antagonistic ability of the AP fungal community and Trichoderma atroviride G79/11 strain against pathogenic fungi was performed. Trichoderma G79/11 developed well on apple pomace and revealed the antagonistic mode against tested fungal plant pathogens. Therefore, it could be applied to soil as a formulation of AP with spores or AP with metaferm biopreparation.
