Construction of Yeast Strains for the Production of Low-Carbohydrate Beer

Abstract: By way of somatic hybridization of a lager browing strain with Saccharomyces diastaticus, a hybrid was constructed, which is suitable for the production of low carbohydrate beer. The hybrid character of the fusion product was confirmed by physiological tests and segregation analyses, as well as, on a molecular basis, by OFAGE (TAFE) and Ty-hybridizatlon.

“…For example, dextrin-utilizing hybrids have been produced using the rare mating technique in which a petite mutant of the parental brewing strain is crossed with an auxotrophic haploid laboratory strain (Tubb et ai., 1981;Goodey and Tubb, 1982). An alternative approach, spheroplast fusion, has been used to produce a dextrin-utilizing hybrid which could be used in the manufacture of a low-carbohydrate beer (Hansen, Rocken and Emeis, 1990). Similarly, Crumplen et al (1990) used the same technique to produce a strain with improved osmotolerance.…”

“…Although several others (Hansen, Rocken, & Emeis, 1990;Spencer, Spencer, & Reynolds, 1988;Vidoli, Yamazaki, Nasim, & Veliky, 1982) have encapsulated fusants in alginate beads to assist in their recovery from protoplast fusion, we are the first, to the best of our knowledge, to investigate this system as a means for long-term stabilization of dikaryons created via protoplast fusion.…”

“…Estas enzimas são as responsáveis pela transformação do amido presente no próprio malte e originalmente na cevada em açúcares para a ação das leveduras e produção de álcool (OETTERER, s.d). (TUBB et al,1981;TUBB, 1982;VAKERIA;HINCHLIFFE, 1989;LANCASHIRE et al, 1989;HANSEN;ROCKEN;EMEIS, 1990) A quinoa foi estudada por Hendges (2014) e a avaliação sensorial das diferentes bebidas obtidas, puro malte, e contendo quinoa malteada como adjunto em diferentes proporções, constatou-se que a aceitação foisemelhante para todas as amostras, quando comparadas a uma amostra de cerveja comercial, e as notas atribuídas foram compreendidas entre "gostei ligeiramente" e "gostei moderadamente". A fermentação do mosto em escala piloto contendo 45% em massa de quinoa malteada, como adjunto, foi avaliada, e foi verificando que as características de pH, de atenuação aparente, de número máximo de células em suspensão e de rendimento em etanol (0,39g/g) foram semelhante às demais condições de bancada avaliadas.…”
