A recombinant chitosanase from Chromobacterium violaceum ATCC 12472 generates chitooligosaccharides with antifungal activity

Mayara Itala Geronimo de Azevedo2020-01-01LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

Chitosan is a polymer of β-D-glucosamine and N-acetyl-β-D-glucosamine subunits, found in the cell wall of fungi. Chitosanases (EC 3.2.1.132) are enzymes capable of degrading chitosan into low molecular weight oligomers. It has been shown that chitosan oligomers exhibit various biological activities, including potent a…

Edible films and coatings based on sulfated polysaccharide from red alga (Hypnea musciformis) incorporated with caffeic acid for application in fish

Jaqueline Alves de Matos2020-01-01LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

There are several materials forming edible films and coatings. In this context, red macroalgae are noted for being rich in sulfated polysaccharides (PS) such as carrageenan, which has good mechanical and barrier properties. The present study aimed to produce edible films based on carrageenan, with different concentrat…
