Abstract: Fructooligosaccharides (FOS) are classified as prebiotic sugar and industrially synthesized by transfructosylation reaction in sucrose molecules catalyzed by fructosyltransferase enzymes adhered to microbial cells. The immobilization of microbial cells in support materials make it possible to obtain robust heterogeneous biocatalysts resistant to adverse conditions of the reaction medium. Loofa Leia mais…

Abstract: Maintaining the enzymatic activity of microbial cells for an extended period is an industrial challenge, because prolonging the life of biocatalysts is an advantage due to reduction in process costs and consequently, reduction in environmental impact. Thus, the objective of this work was to evaluate the biochemical stability of Leia mais…

Abstract: Listeria monocytogenes is a foodborne pathogen that contaminates food-processing environments and persists within biofilms on equipment, thus reaching final products by cross-contamination. With the growing demand for clean-label products, the search for natural antimicrobials as biopreservants, such as bacteriocins, has shown promising potential. In this context, this study aimed Leia mais…

Abstract: Different reaction control methods for producing nano/microstructures of poly(butyl cyanoacrylate) (PBCA) have been studied, focusing on pH and monomer-to-initiator ratios. However, these methods often require multiple steps and reagents. In the synthesis of PBCA microparticles using three versions of micromixers designed with HH geometry and varying numbers of channels Leia mais…

Resumo: As incrustações de carbonato de cálcio (CaCO3) em dutos de extração de petróleo acarretam significativas perdas financeiras sendo proposto a aplicação de campos magnéticos como uma solução eficiente em sua mitigação, um método de baixo custo econômico/ambiental. Este estudo objetiva investigar o impacto do campo magnético quando aplicado em Leia mais…
