| dc.description.abstract | Los PBF seleccionados mostraron efecto bacteriolítico sobre Serratia in vitro. La viabilidad de la célula objetivo se redujo significativamente tras una co-cultivación de 1 h, induciendo varias modificaciones morfológicas y ultraestructurales. Sumergir fresas en la fase madura cuatro en PBFs no indicó un aumento en el recuento total de células, por lo que la colonización de microorganismos se mantuvo durante el almacenamiento con refrigeración. El análisis del metagenoma 16S mostró que el tratamiento afectó a la microbiota frutal, aumentando significativamente la abundancia de Lactobacillus (p < 0,001) al octavo día en comparación con el control desinfectante. Esto sugiere que la formulación apoya microbios beneficiosos, potenciando los efectos antimicrobianos. Además, el recubrimiento postbiótico mejoró la vida útil, conservó la calidad de los frutos y retrasó el deterioro de las fresas. Los atributos de calidad de las fresas no se vieron afectados por el tratamiento. El Análisis de Componentes Principales (PCA) reveló una separación clara de la muestra basada en la etapa de madurez, independientemente del tratamiento. | es_EC |

| dc.description.abstract-en | The selected PBFs showed bacteriolytic effect on Serratia in vitro. The target cell viability was significantly reduced upon 1 h co-cultivation by inducing several morphological and ultrastructural modifications. Dipping strawberries at the ripe stage four in PBFs indicated no increase in total cell counts, thus the microorganisms colonization was retained during storage with refrigeration. The 16S metagenome analysis showed that the treatment impacted the fruit microbiota, significantly increasing Lactobacillus abundance (p < 0.001) by day eight compared to the disinfectant control. This suggests the formulation supports beneficial microbes, enhancing antimicrobial effects. Additionally, the postbiotic coating improved shelf-life, preserved fruit quality, and delayed deterioration in strawberries. The strawberries quality attributes were not affected by the treatment. Principal Component Analysis (PCA) revealed clear sample separation based on maturity stage, independent of the treatment. | es_EC |
