Etanol No Brasil: Evolução Do Patenteamento De Tecnologias De Fermentação Para a Produção De Etanol Combustível De Cana-De-Açúcar No Período De 2007 a 2014

Abstract: RESUMOÉ realizada uma análise do panorama tecnológico atual do etanol combustível de cana-de-açúcar no Brasil a partir da análise de documentos de patentes depositados no país, especificamente, para os processos de fermentação, considerando a 1ª geração e 2ª geração separadamente. Os resultados apontam para uma retração de investimentos na proteção intelectual das tecnologias de fermentação no Brasil após 2008, mas, também identificam grandes players internacionais no campo das biotecnologias atuando no contex… Show more

“…Due to their ease of acquisition and handling, the fungus Saccharomyces cerevisiae and the bacterium Zymomonas mobilis are the most used microorganisms in biomass fermentations, as they have high yields of ethanol rates. Values around 70-80% and higher at converting hexoses can be reached, despite their inactivity with xylose-the main pentose of hemicellulose (Hasner et al, 2015). There are other types of microorganisms popular for being able to ferment hexoses and pentoses, such as Scheffersomyces stipitis and Candida shehatae; however, with limitations such as low consumption of sugars (Mengesha et al, 2022).…”
