Design of new immobilized lipases for biotransformations in aqueous and organic media
(Universidade Federal de São Carlos, 2023-01-30)
A review of the literature covering research on the immobilization of lipases on hydrophobic supports was performed using systematic mapping (MS) concepts. The MS approach enabled the identification of gaps that led to the ...
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 ...
Síntese de ésteres graxos de açúcar catalisada por derivados imobilizados-estabilizados de candida antarctica lipase B
(Universidade Federal de São Carlos, 2023-03-21)
The biotechnology industry is increasingly seeking to deploy high productivity and stable biocatalysts for commercial-scale production of bioproducts. In addition, with global warming, enzyme-based production systems using ...
Produção de celulases por Myceliophthora thermophila I-1D3b em resposta a diferentes fontes de carbono e taxas de aeração em cultivos sólido e submerso
(Universidade Federal de São Carlos, 2023-02-24)
The interest in cellulolytic systems of thermophilic fungi motivated the development of research aimed at the use of their enzymes in various industrial sectors, such as in the production of biofuels, particularly ...
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 ...
Photocatalytic degradation of organic pollutants through peroxymonosulfate activation: photocatalysts and reaction mechanisms
(Universidade Federal de São Carlos, 2023-06-30)
Water pollution from organic compounds has become a growing concern worldwide due to the risks imposed on human health and the environment. The rapid advancements in the pharmaceutical and agricultural industries have ...
Previsão da composição e dos volumes das fases durante a cinética enzimática do biodiesel etílico com lipase líquida utilizando modelo UNIFAC
(Universidade Federal de São Carlos, 2023-06-29)
The production of biodiesel catalyzed by lipases, especially by transesterification of vegetable oils, has been gaining importance in recent decades because it is an efficient and sustainable process. The main differential ...
On the drag coefficient in particle agglomerates: a CFD approach to propose a new drag correlation
(Universidade Federal de São Carlos, 2023-07-31)
In particle-laden flows, it is essential to model the fluid-particle interaction. However, depending on effects such as friction and attraction, surface properties, and collisions, particles can agglomerate, generating new ...
