Antibacterial and hypoglycemic activity in vitro of polysaccharide obtained fro...
Chaves, Anny Carolinny Tigre Almeida; Queiroz, Raphael Ferreira; Assis, Sandra Aparecida deFungi are source of polysaccharides that can show biological activity. The objective of this research was obtained polysaccharides from Periconia byssoides and evaluate antibacterial and hypoglycemic activity in vitro. The number-average molecular weight and degree of polymerization were determined. The results show that the polysaccharide of P. byssoides has potential as hypoglycemic. Therefore, it would be in...
Inulinase from Rhodotorula mucilaginosa: immobilization and application in the ...
Ribeiro, Geise Camila de Araújo; Fernandes, Pedro Carlos de Barros; Silva, Dayse Alessandra Almeida; Brandão, Hugo Neves; Assis, Sandra Aparecida deThe crude extract containing inulinase from Rhodotorula mucilaginosa was obtained by submerged fermentation. Inulinase was immobilized on chicken eggshell by physical adsorption and covalent crosslinking, using glutaraldehyde as a crosslinking reagent, and Celite by adsorption. Fructooligosaccharides production was performed using immobilized inulinase (5%, w/v) and inulin substrate solution under experimental ...
Production, characterization, and immobilization of protease from the yeast Rho...
Oliveira, Juliana Mota de; Fernandes, Pedro Carlos de Barros; Benevides, Raquel Guimarães; Assis, Sandra Aparecida deThe protease was produced extracellularly in submerged fermentation by the yeast Rhodotorula oryzicola using different sources of nitrogen and maximum activity (6.54 × 10−3 U/mg) was obtained in medium containing 2% casein (w/v). Purification of the protease by gel filtration chromatography resulted in a 3.07-fold increase of specific protease activity. The optimal pH and temperature for enzyme activity were 6....
