| Popis: | In this study, the production of siderophores by Xylella fastidiosa from the citrus bacteria isolate 31b9a5c (FAPESP - ONSA, Brazil) was investigated. The preliminary evidence supporting the existence of siderophore in X. fastidiosa was found during the evaluation of sequencing data generated in our lab using the BLAST-X tool, which indicated putative open reading frames (ORFs) associated with iron-binding proteins. In an iron-limited medium siderophores were detected in the supernatant of X. fastidiosa cultures. The endophytic bacterium Methylobacterium extorquens was also evaluated. Capillary electrophoresis was used to separate putative siderophores produced by X. fastidiosa. The bacterial culture supernatants of X. fastidiosa were identified negative for hydroxamate and catechol and positive for M. extorquens that secreted hydroxamate-type siderophores. |
