Resumo: | Brazil and Mexico have typical and world-known distilled drinks, cachaça and tequila. The production of these distillates is similar and both generate a liquid residue, known as vinasse. This residue presents high polluting degree and needs alternatives for its use. Proposals of direct use and treatment of vinasse are known, but inefficient and applicable in the long run. It is in this context, the use of vinasse could be the viable alternative for the economy and the environment. Yeasts from different substrates from Brazil and Mexico were tested for their ability to produce biomass and volatile compounds of industrial interest from this residue. Statistical models were used to evaluate different cultivation conditions in the optimization of biomass production. The biomass generated was evaluated by dry weight. Analyzes of nutritional and anti-nutritional factors were performed Yeasts showed best performance were used in the evaluation for the production of volatile compounds using tequila and cachaça vinasse. Composition and quantification of the volatile compounds were carried out by HS-GC-FID (Headspace in Gas Chromatography coupled to the Flame Ionization Detector). The results indicated that the use of vinasse can be an economically viable way for production of single cell protein and volatile compounds, along with the reduction of pollutant parameters. The main volatile compound detected was 2-phenylethanol. So, yeasts growth, when conditions are adjusted, can be a promising alternative in the production of high added value products. |

A produção destes destilados é similar e apresentam um processo de produção que gera o resíduo liquido denominado vinhoto. Esse resíduo possui alto grau poluidor e necessita de alternativas para o seu aproveitamento. Propostas do uso direto e tratamento do vinhoto são conhecidas, mas ineficientes e aplicáveis à longo prazo. É neste contexto que o uso do vinhoto pode ser a alternativa viável para a economia e ao meio ambiente. Dessa forma, foram testadas leveduras de diferentes substratos do Brasil e do México quanto à capacidade de produzirem biomassa e compostos voláteis de interesse industrial a partir do vinhoto. Modelos estatísticos foram utilizados, para avaliar diferentes condições de cultivo na otimização da produção de biomassa. A quantidade de biomassa foi avaliada por peso seco. As análises de fatores nutricionais / anti-nutricionais foram realizadas na biomassa do isolado que apresentou maior produtividade. As leveduras que apresentaram bom desempenho foram avaliadas quanto a produção de compostos voláteis utilizando vinhoto de tequila e cachaça. A composição/quantificação dos compostos voláteis foram realizadas por HS-GC-FID (Headspace em Cromatografia gasosa acoplada ao Detector de ionização em Chama). Os resultados indicaram que o uso do vinhoto pode ser uma maneira econômica para a produção de “single cell protein” e compostos voláteis, aliados à redução de parâmetros poluidores. Leveduras selecionadas no aproveitamento do resíduo, quando em condições são ajustadas, pode ser uma alternativa promissora na produção produtos de alto valor agregado.Universidade Federal de LavrasPrograma de Pós-Graduação em Microbiologia AgrícolaUFLAbrasilDepartamento de BiologiaBatista, Cristina Ferreira Silva eSchwan, Rosane FreitasGaviño, Javier Arrizon PlacidoMathis, Anne Christine GschaedlerPlaza, Melchior ArellanoReis, Kelly Cristina dos2017-04-28T13:44:35Z2017-04-28T13:44:35Z2017-04-202017-02-22info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfREIS, K.
