Producción de metabolitos secundarios mediante fermentación líquida a partir de Trichoderma y Bacillus para el control de hongos aislados de pitahaya roja (Hylocereus Undatus)

Abstract

This study evaluates the antimicrobial activity of secondary metabolites produced from the liquid fermentation of Bacillus and Trichoderma against eleven strains isolated from symptoms of red dragon fruit (Hylocereus undatus) which were identified at the molecular level as; Fusarium dimerum, Fusarium verticillioides, Fusarium falciforme, and Curvularia cactivora, using various bioinformatics tools, these being Finch TV, Geneious primer, and NCBI. Where in vitro tests were carried out to evaluate the antimicrobial capacity of the secondary metabolites produced, using the agar well diffusion method, evidencing that the secondary metabolites produced by Bacillus have antimicrobial activity against the isolated strains, while those derived from Trichoderma did not present antimicrobial activity in any of them.
