Functional characterization of TasA and TapA in the formation of the amyloid fiber in Bacillus subtilis
Cámara-Almirón, Jesús; Morel, Bertrand; Conejero-Lara, Francisco; Romero, Diego (2017-06-30)Introduction Functional amyloids are a very heterogeneous family of amyloid proteins widespread in nature, from humans to bacteria. Unlike their “pathogenic” relatives, implicated in several neurodegenerative diseases, ... -
A locus widely distributed in the B. cereus group with functionality in biofilm formation
Álvarez-Mena, Ana; Caro-Astorga, Joaquín; Antequera-Gómez, Maria Luisa; De-Vicente-Moreno, Antonio; Romero, Diego (2018-10-17)
Bacillus cereus is a human pathogen responsible of a series of food poisoning due to the consumption of contaminated vegetables or processed foods. The production of spores and the organization in communities called biofilms, ... -
Una mirada "positiva" a los biofilms bacterianos
Romero, Diego (2014-10-14)Las bacterias son organismos unicelulares, pero que también tienden a agruparse en comunidades multicelulares conocidas como biofilms. Para que este agrupamiento ocurra, la población bacteriana tiene que sincronizarse, y ... -
The pivotal functionality of the amyloid protein TasA in Bacillus physiology and fitness
Cámara-Almirón, Jesús; Navarro, Yurena; Magno, M. Concepción; Molina, Carlos; De-Vicente-Moreno, Antonio; Pérez-García, Alejandro
; Romero, Diego[et al.] (2018-12-13)
Biofilms are complex bacterial communities formed on any surface and composed of cells embedded in an extracellular matrix, in which the amyloid protein TasA is the major protein component. It has been demonstrated that ... -
Una región genómica implicada en la formación de fibras tipo amiloide en biofilms de Bacillus cereus
Pérez-García, Alejandro; De-Vicente-Moreno, Antonio
; Romero, Diego; Caro-Astorga, Joaquín (2015-03-27)
Bacillus cereus es una bacteria patógena responsable de numerosos brotes de intoxicación alimentaria. Las esporas y el biofilm son considerados los reservorios más importantes de B. cereus que se pueden encontrar en frutas ... -
The complete genome analysis of Bacillus amyloliquefaciens UMAF6614 and UMAF6639 reveals genetics features involved in biocontrol activity and bacterial fitness
Magno, M. Concepción; Martínez, Pedro; De-Vicente-Moreno, Antonio; Romero, Diego; Rodríguez-Palenzuela, Pablo; Pérez-García, Alejandro
[et al.] (2014-07-24)
The Bacillus amyloliquefaciens strains UMAF6614 and UMAF6639 were originally isolated from healthy leaf areas of melon plants naturally infected with the cucurbit powdery mildew fungus Podosphaera fusca. In previous works, ... -
The expression profile of secondary metabolites in biofilms of B. amyloliquefaciens CECT 8237 biocontrol strain
Magno, M. Concepción; Hierrezuelo, Jesús; De-Vicente-Moreno, Antonio; Pérez-García, Alejandro
; Romero, Diego (2017-07-20)
The contribution of Bacillus amyloliquefaciens CECT 8237 (UMAF6639) strain to the plant protection against bacterial and fungal pathogens is mainly based on: i) the production of antimicrobial compounds, ii) the plant-growth ... -
Tse1 mobilized by T6SS of Pseudomonas induces sporulation of Bacillus via σW
The extracellular matrix and sporulation are defensive mechanisms used by Bacillus cells when they interact with Pseudomonas strains expressing a type VI secretion system (T6SS). Here, we define Tse1 as the main toxin ...
