14. Evaluation of oat hull hemicellulosic hydrolysate fermentability employing Pichia stipitis
Oat hull hemicellulosic hydrolysate obtained by diluted acid hydrolysis was employed as fermentation medium for Pichia stipitis cultivation. A comparison between the use of treated hydrolysate with 1% activated charcoal to reduce the toxic compounds generated during the hydrolysis process and untreated hydrolysate as a control was conducted. In the cultures

16. Sistema fermentativo de duas fases para a produção de hidrogênio e metano a partir de esgoto sanitário combinado com águas residuárias industriais / Two phase fermentative for hydrogen and methane production from domestic wastewater combined with industrial wastewaters
A possibilidade da produção de hidrogênio a partir de esgoto sanitário com a posterior geração de metano a partir do efluente do processo acidogênico foi avaliada em reatores anaeróbios em batelada e contínuos. Nos reatores em batelada com biomassa acidogênica não houve produção de hidrogênio a partir de esgoto sanitário, o que motivou a avali

20. Resposta de Saccharomyces cerevisiae ao estresse de alta pressão hidrostática. / Saccharomyces cerevisiae response to the stress of high hydrostatic pressure.
As leveduras, principalmente Saccharomyces cerevisiae, são as responsáveis direta pela transformação do açúcar em álcool etílico e dióxido de carbono, sendo por isso, um dos microrganismos mais importantes empregados nas indústrias de fermentação, seja de bebidas ou etanol combustível. Durante o processo de fermentação as leveduras ficam expos
