Most studies selecting antagonistic microorganisms have focused on one pathosystem and then extended to others, but this approach was not a viable alternative for mango decay which is caused by a pool of pathogens in the tropics. In this study, 182 yeast isolates were isolated from ripe fruits of native wild plant species and other fruit crops from the Brazilian semi-arid region and selected against four prevalent agents of mango decay in tropical regions. The largest number of isolates was obtained from table and wine-grapes, followed by the native Spondias tuberosa. In dual culture assays, 8.8% of the yeast isolates showed growth inhibition halos of at least one of the pathogens. However, only six yeasts reduced the development of lesions in vivo to less than 50% to all the pathogens. Yeast/pathogens co-inoculation in healthy mango fruits in semi-commercial conditions showed that S. cerevisiae ESA45, Saccharomyces sp. ESA47 and Pichia kudriavzevii CMIAT171 had the larger spectrum of control efficiency, significantly reducing rot incidence and severity of all pathogens. The isolates also showed a variable tolerance to abiotic stress and biomass production. These results show the potential of these epiphytic yeasts as biocontrol agents of multiple pathogens infection in mango fruits. |

This study presents the preparation of polypropylene composites filled with mixtures of household waste of mate-tea and wood particles to increase the economic value chain of mate-tea, especially in Latin America. Filler mixtures in proportions ranging from 0 to 60% depending on the type of particle were used. The polypropylene matrix was fixed at 40% and roughness surface and color evaluation were performed. The highest mean roughness (Ra) was observed for the composite with 30:30% proportion of filler mixture, which denotes the difficulty of homogenizing a mixture of fillers with different shapes and dimensions. Nevertheless, even with higher roughness for composites with a balanced blend of filler, this does not imply the presence of large peaks and valleys. In general, all the composites presented a dark color. Variation of color composites was more evident for higher proportions of household waste of mate-tea. |
