Bacterial spot, which is the main disease occurring in passion fruit trees, is caused by the bacterium Xanthomonas axonopodis pv. passiflorae, leading to large annual losses in passion fruit crops. This study aims to find extracts and/or bioactive compounds of endophytic fungi of noni (Morinda citrifolia) to treat bacterial spot in passion fruit trees. Nine fungi isolated from a specimen of M. citrifolia from the Brazilian Amazon are studied. The fungus Guignardia mangiferae NF17 shows the best inhibition results and is selected for the isolation of its secondary metabolites by chromatography techniques. The isolated compounds Sydowinol (S1) and Sydowinin A (S2) are identified by nuclear magnetic resonance (NMR). Compounds S1 and S2, as well as the acetonitrile extract from the biomass of G. mangiferae NF17, are tested against four strains of X. axonopodis pv. passiflorae obtained from plants infected by bacterial spot, and which inhibited bacterial growth up to the lowest concentration tested (3.125 μg/mL). This study reports, for the first time, the antibacterial activity against X. axonopodis pv. passiflorae by the compounds Sydowinol and Sydowinin A. Compounds S1 and S2 are reported for the first time for the genus Gignardia. |

Strawberry is a small fruit considered one of the most appreciated berries by the Brazilian population, for its pleasant flavour and source of vitamin C. However, it is a highly perishable fruit due to postharvest pathological problems, mainly caused by Botrytis cinerea fungus. To decrease this problem, edible coatings can be an alternative because are considered an environmentally friendly technology, used to preserve and extend the postharvest shelf life. The aim of this study was to evaluate two edible coatings: the sodium alginate and carboxymethyl cellulose to keep quality and extend shelf life of strawberries. The produced coat was obtained from the spreading of film-forming solution on glass petri dishes and dried for 48 h in a vacuum oven to study its physical and chemical characteristics. Strawberries were immersed in the coating solution and stored at refrigeration temperature (2?4.5°C). Thermogravimetric analysis, film thickness and weight loss percentage of the coated and control samples were performed. The thickness of each film was measured using a micrometer. Thermogravimetric analysis was performed using a thermogravimetric analyzer. The films exhibited thickness from 0.015 to 0.06 mm. Weight loss percentage were not significantly different (p>0.05) in coated strawberries compared to the control. Thermogravimetric analysis showed similar decomposition curves for films produced. The results showed good thermic stability of films. Edible coating prevented Botrytis injuries when stored up to 5 days at refrigeration temperature (2?4.5°C). Concerning the weight loss percentage there was no significative difference between coated and control. Therefore, with a visual observation it was verified that strawberry coated presented higher quality characteristics than control. The next stage of the project will be dedicated to functionalizing the coating with nanoparticles with antimicrobial potential and evaluate how this functionalization interferes on the biological activity and other rheological properties of the films.
