| Summary: | The goal of this work was to select strains of fermentation yeasts and test them in a small-scale production of " umbu" fruit wine. The fruits were collected in N. Sra da Glória city in Sergipe, Brazil. The fruit pulp was diluted and aliquots were inoculated on YMA plates. The yeasts strains were submitted to fermentation using "umbu" fruit juice as substrate, exception with to those strains of species related to pathological processes. The yeasts tested produced a beverage characterized between dry to light due to its alcoholic content with very nice taste, translucent appearance, of green to light yellow color.<br>As leveduras são essenciais na fabricação de bebidas alcoólicas devido a sua alta capacidade de fermentação. Dessa forma, o objetivo deste trabalho foi selecionar linhagens de leveduras fermentadoras e testá-las na produção de vinho semi-artesanal. Os frutos foram coletados em Nossa Senhora da Glória - SE, Brasil. A polpa foi diluída e alíquotas foram inoculadas em placas contendo YMA. Após essa etapa foi realizadas a seleção, purificação e identificação dos morfotipos. As leveduras foram posteriormente submetidas ao teste de fermentação, excetuando-se aquelas relacionadas a processos patológicos, As leveduras testadas produziram vinhos com teor alcoólico que os caracterizaram entre seco e suave, sabor e aparência agradáveis, translúcidos, e cor intermediária entre o verde e o amarelo claro. |
