Development of integrated strategies using non-recombinant yeast for 2G ethanol production from lignocellulosic materials
(Universidade Federal de São Carlos, 2023-01-31)
The viability of second-generation (2G) ethanol production still requires overcoming some bottlenecks, such as the underutilization of the hemicellulosic fraction of biomass and process improvements to reach higher ...
Liquid-solid fluidized bed dynamics: experimental and computational analysis
(Universidade Federal de São Carlos, 2023-11-06)
The liquid-solid fluidization is a simple process intensification strategy. The method remains underexplored, in part, due to the lack of predictability. It is not trivial to assess its internal dynamics without a robust ...
Avaliação da fermentação alcoólica extrativa em diferentes temperaturas com remoção de etanol por arraste com CO2
(Universidade Federal de São Carlos, 2023-02-23)
By reducing the fermentation temperature, the inhibitory effect of ethanol is also reduced, resulting in wines with higher ethanol contents, but with a significant decrease in ethanol productivity, due to the negative ...
Encapsulamento de Trichoderma harzianum em matrizes à base de nanocelulose e carboximetilcelulose para aplicação na agricultura
(Universidade Federal de São Carlos, 2023-06-21)
Microbial inoculants are a sustainable alternative to increase agricultural productivity and reduce environmental and health problems caused by the exacerbated use of agrochemicals. These bio-based products are formulations ...
Borra de café: análise da caracterização termoquímica, do processo de elutriação, secagem, peletização e da mistura com outros resíduos
(Universidade Federal de São Carlos, 2023-04-27)
For the reuse of the spent coffee grounds, this thesis has two main strategies, the first is to evaluate its granulometry as a function of the thermal degradation behavior, the elutriation, drying process, pelletization ...
Sistema multienzimático inovador para a produção de ácido glicônico a partir de amido usando células inteiras de Aspergillus niger
(Universidade Federal de São Carlos, 2023-11-28)
Gluconic acid occurs naturally in a wide variety of foods, including fruit, honey, wine, rice, meat and other naturally fermented products. Because of its versatility and biodegradability, it has many applications in the ...
Efeito de forças hidrodinâmicas em colisões partícula-superfície em diferentes meios fluidos
(Universidade Federal de São Carlos, 2023-12-20)
Energy dissipation in systems, such as solid-gas and solid-liquid, can occur in several ways, including resistance to motion, interfacial interactions, deformation, and particle collision. In gas-solid flows, the main ...
