Caracterización molecular ómica de una cepa de Bacillus amyloliquefaciens aislada de la microbiota del paiche Arapaima gigas con actividad antagonista contra bacterias patógenas de peces

Abstract: Se analizaron las características de una cepa de Bacillus amyloliquefaciens aislada del intestino de Arapaima gigas, seleccionada por su capacidad para generar inhibición de múltiples bacterias patógenas de peces, mediante el uso de herramientas moleculares como PCR y espectrometría de masas - MALDI TOF/TOF. Los resultados mostraron a través de PCR que esta cepa cuenta con genes claves para la generación de péptidos antimicrobianos como bmyB (bacillomycin L synthetase B), fenD (fengycin sintetasa), srfAA (subu… Show more

“…In the collection stage, the strawberry rhizosphere soil was used as a sample to obtain the Bacillus spp strains, similar to a work reported in the rhizosphere of cacti [19]. On the contrary, studies have been carried out where they obtain samples of mites [20], plants [21], fish [22], birds, bovines [23], fungi [24] among others. In this work, rhizospheric soil is used due to the high diversity of microbiota and the environmental conditions that favor the development of the genus Bacillus spp due to its close relationship with the roots of vegetable crops [25].…”
