Its production, like that of most agricultural products, is affected by the emergence of diseases caused by microorganisms, generating significant losses in production. Natural extracts with antimicrobial activity are considered an alternative to control the emergence of these diseases. The purpose of this work was the identification of a microorganism isolated from the diseased tamarillo and the evaluation of the antimicrobial activity on this of extracts obtained from mint, oregano, papaya seeds and orange peel. The extracts were obtained; using hydrodistillation and the Soxhlet extraction method. By the first method, only the oily phase could be extracted from the orange peel; for the rest of the materials, aqueous extracts were obtained. While by Soxhlet the oily phase of mint, oregano and papaya seeds was recovered. The microorganism that was isolated was identified in the company AOXLAB as Colletotrichum acutatum and the minimum inhibitory capacity of the extracts obtained on it was evaluated. This allowed determining that the oily extract of the papaya seeds was the only one capable of inhibiting the fungus with a concentration of 1250 mg/L. The oily papaya extract was subsequently nanoencapsulated in niosomes in order to compare its encapsulated and unencapsulated antimicrobial potential. This test allowed finding that the encapsulation process reduces the required minimum inhibition concentration to 78.13 mg/L.Ítem Formación de películas comestibles a base de biopolímeros para la conservación de frutas(Universidad EAFIT, 2022) Aguilar Barahona, Sara; Paniagua Arboleda, Darlene Audrey; Giraldo Estrada, Catalina; Hernández Tenorio, Fabián EnriqueÍtem Genomic annotation and gene expression analysis related to oil production of the non-model crop Plukenetia volubilis(Universidad EAFIT, 2021) Florian Cruz, Andrés Felipe; Villanueva Corrales, Simón; Villanueva Corrales, Simon; Correa Alvarez, JavierÍtem In vivo study : effect of essential oils and lipopeptides from Bacillus tequilensis EACB0015 on the growth of the phytopathogenic fungus Colletotrichum Acutatum EAHP-012(Universidad EAFIT, 2021) Orozco Vergel, Joana Paola; Gómez Ramírez, Luis Alejandro
