“…Batch fermentation is widely used in industry because it is easy to operate and low risk to be contaminated [26]. However, batch ABE fermentation has several drawbacks such as low productivity and low production due to product inhibition [27, 28]. Fed-batch mode by feeding concentrated medium cannot be applied with ABE fermentation without in situ removal of butanol to alleviate its severe inhibition to cells [16, 28].…”

“…Continuous fermentations have some advantages compared to batch processes: a significant reduction in downtime by elimination of idle times (charge, discharge, cleaning and sterilization of vessel), higher productivity and easier automatic operation [16]. Its high productivity and low lag-phase make it more suitable for large-scale butanol fermentation in comparison with batch mode [27]. However, the traditional one-stage free cell continuous fermentation may provide higher volumetric productivity but lower product concentration than batch fermentation [15].…”

Background Butanol production by fermentation has recently attracted increasingly more attention because of its mild reaction conditions and environmentally friendly properties. However, traditional feedstocks, such as corn, are food supplies for human beings and are expensive and not suitable for butanol production at a large scale. In this study, acetone, butanol, and ethanol (ABE) fermentation with non-pretreated cassava using a symbiotic TSH06 was investigated. Results In batch fermentation, the butanol concentration of 11.6 g/L was obtained with a productivity of 0.16 g/L/h, which was similar to that obtained from glucose system. A full utilization system of cassava was constructed to improve the fermentation performance, cassava flour was used as the substrate and cassava peel residue was used as the immobilization carrier. ABE fermentation with immobilized cells resulted in total ABE and butanol concentrations of 20 g/L and 13.3 g/L, which were 13.6% and 14.7% higher, respectively, than those of free cells. To further improve the solvent productivity, continuous fermentation was conducted with immobilized cells. In single-stage continuous fermentation, the concentrations of total ABE and butanol reached 9.3 g/L and 6.3 g/L with ABE and butanol productivities of 1.86 g/L/h and 1.26 g/L/h, respectively. In addition, both of the high product concentration and high solvent productivity were achieved in a three-stage continuous fermentation. The ABE productivity and concentration was 1.12 g/L/h and 16.8 g/L, respectively. Conclusions The results indicate that TSH06 could produce solvents from cassava effectively. This study shows that ABE fermentation with cassava as a substrate could be an efficient and economical method of butanol production.

“…The butanol, whose chemical formula was assigned as C 4 H 9 OH, conventionally could be derived from the carbohydrate (biomass) through hydrolysis and fermentation employing strain Clostridia (C. beijerinckii and C. acetobutylicum) [16]. The property of butanol, which is close to petroleum, is a density measured at 806 kg/m 3 [17].…”

The work was purposed to identify the compositions the blended fuel of butanol, gasoline, and water forming the stable emulsions at low temperatures. The previous researches reported that the blending of butanol and gasoline generally employed the synthetic surfactants which were expensive and mixed at room temperatures. It is important to analyze the stability of the substances in the wide range of temperature for it alter significantly on the surface of the planet. The references survey revealed that the works of the compositions of the wet butanol and gasoline at low temperatures are yet published. The present work was successful to blend the butanol, gasoline, and water in stable emulsion without using the surfactant and stabilized in the less of room temperature. Compositions of butanol, gasoline (RONs 90), and water emulsified and stabilized at low temperatures without synthetic surfactants were successfully studied. It was found that aqueous butanol and gasoline formed a stable emulsion at low temperatures and discovered the phase was separated if temperature declined. The compositions of pure butanol, gasoline, and water recorded in stable emulsions using butanol 85.00 % ranged from 75.08–79.24 %, 6.77–11.67 %, and 13.25–13.98 %, respectively, blended at temperatures 0.00–29.70 °C. The usage of butanol 99.50 % caused the change of compositions recorded at 0.71–11.34 %, 88.61–99.29 %, and 0.00–0.06 % blended at 0.00–29.00 °C. It was discovered that the increase of butanol percentage of the fuel after the emulsion was stable tended to the emulsion kept one phase. The emulsion fuels found would be applied to the heat-modified engines operating in wide range temperatures which were below room temperature

“…Os métodos ISPR são definidos como tecnologias de recuperação seletiva que podem operar de modo contínuo ou intermitente. De fato, a implementação dessas técnicas contribuem na redução da produção de vinhaça e dos custos com separação dos produtos e tratamento de água (MAITI et al, 2016;QURESHI, 2015). Além disso, valores de produtividade e demais índices de desempenho apresentam melhores resultados quando comparados ao processo em batelada.…”

Ao fim desse trabalho, eu notei o quanto a ciência se faz de resiliência. O indivíduo pode perseverar ou desistir em frente às adversidades que surgem. E, eu aprendi que o lado para o qual a balança pende depende de mim, mas se fortalece com a ajuda das pessoas que fazem a diferença. A elas, eu gostaria de dedicar este agradecimento.Primeiramente, agradeço ao Prof. Dr. Adriano Mariano por ser meu orientador no sentido mais genuíno da palavra e compartilhar das minhas preocupações e problemas nas reuniões de sexta à tarde.Agradeço também aos meus amigos, pois sem alguns deles talvez eu não estivesse aqui. Tamara, Gabi, Jéssica e Leila, o apoio de vocês me trouxe de Natal a Campinas. Carol, você me acolheu e acreditou enquanto eu duvidava. Meus amigos de laboratório (LOPCA e LSOPQ), vocês foram meus companheiros nessa longa caminhada pelos bosques acadêmicos; em especial, Júnia que adora petróleo, mas discute comigo sobre "bio-coisas". E, Luiz, meu amigo e roommate, que me apoia e me ama sem saber o porquê.Por fim, gostaria de agradecer a Faculdade de Engenharia Química pela infraestrutura, corpo docente e demais funcionários. Assim como a Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) pelo apoio financeiro, processo nº: 2016/08791-5."Porque o conhecimento é a única coisa que ninguém pode tirar de você". Gilvaneide Silva RESUMOO n-butanol de origem verde pode ser produzido via fermentação ABE (acetona-butanol-etanol) ou IBE (isopropanol-butanol-etanol) através de bactérias do gênero Clostridium; no entanto, ambos os processos enfrentam dificuldades para estabelecer a competitividade de produção.Destaca-se a inibição dos microrganismos pelos produtos como um dos principais obstáculos. De fato, essa problemática é ainda mais crítica na fermentação IBE, cujo valores de conversão de açúcares (59%), produtividade de butanol (0,13 g/L‧h) e rendimento de butanol (0,17 g/g) são inferiores ao desempenho da rota de fermentação ABE. A fim de mitigar os efeitos de inibição das células causado pelos solventes, o método de recuperação dos produtos in situ via separação a vácuo foi aplicado sob a configuração de "fermentação flash". Além disso, desenvolveu-se um caso hipotético de modificação genética e seus desdobramentos no desempenho das tecnologias de fermentação convencional batelada e "fermentação flash" foram verificados. O principal objetivo foi o desenvolvimento e a avaliação técnico-econômica da produção de n-butanol lignocelulósico via fermentação IBE através de processo com tecnologia avançada. Para tal, os estudos foram conduzidos através de simulações computacionais que permitiram determinar condições operacionais ótimas da "fermentação flash" para máxima produtividade de IBE ou mínima taxa de vaporização no tanque flash, além de alimentarem as análises econômicas de distintas estratégias de negócio. Por fim, observou-se que a tecnologia de "fermentação flash" promoveu caldos menos diluídos em produtos e aumento da produtividade, cuja condição ótima de minimização da quantidade de caldo vaporizado ...
