Abstract: The immobilization of fructosyltransferase enzymes has been identified as an essential strategy for the production of fructooligosaccharides (FOS) in heterogeneous reaction systems. This study investigated the applicability of silica gel and silica gel functionalized with glutaraldehyde as porous inorganic supports for the immobilization of the extracellular fructosyltransferase from Aspergillus Leia mais…

Abstract: This study investigated the effect of low-cost carbon and nitrogen sources on fructosyltransferase (FTase) production by Aspergillus oryzae IPT-301, aiming to optimize the enzymatic synthesis of fructooligosaccharides (FOS), prebiotic compounds valued for their bifidogenic effects. FTase is a key enzyme in transfructosylation, the central step in FOS production. To Leia mais…

Abstract: MDMA and MDA are among the stimulant drugs most frequently encountered in forensic casework, and oral fluid represents a practical biological matrix for their detection. However, liquid oral fluid requires refrigeration, is susceptible to degradation, and can be logistically demanding for routine laboratories. Dried Oral Fluid Spots (DOFS) offer Leia mais…
