Journal ArticleDOI
Cellulase and Xylanase Expression in Response to Different pH Levels of Penicillium echinulatum S1M29 Medium
Laísa dos Reis,Willian Daniel Hahn Schneider,Roselei Claudete Fontana,Marli Camassola,Aldo José Pinheiro Dillon +4 more
TL;DR: Different isoforms of the endoglucanases were found in the various cultures depending on the pH, and more acidic pH ranges favored the production of β-glucosidases in both the shake flask and the bioreactor.
Journal ArticleDOI
Effect of freezing and processing technologies on the antioxidant capacity of fruit pulp and jelly
Cristine Maso Jeusti Bof,Roselei Claudete Fontana,Luciani Tatsch Piemolini-Barreto,Ivana Greice Sandri +3 more
TL;DR: In this article, the effect of freezing and processing technology on the antioxidant capacity of grape (Vitis vinifera), apple (Malus domestica), strawberry (Fragaria x Anassa), pear (Pyrus communis L.), guava (Psidium guajava L.), and fig (Ficus carica L.) was evaluated for 90 days.
Journal ArticleDOI
Production of edible mycoprotein using agroindustrial wastes: Influence on nutritional, chemical and biological properties
Fernanda Stoffel,Fernanda Stoffel,Weslei de Oliveira Santana,Jean Guilherme Novello Gregolon,Tarso B. L. Kist,Roselei Claudete Fontana,Marli Camassola +6 more
TL;DR: Mycoproteins produced in brewer-spent grain and grape bagasse could be a strategy to increase the nutritional value and biological activity of these agroindustrial residues.
Journal ArticleDOI
Chemical features and bioactivity of grain flours colonized by macrofungi as a strategy for nutritional enrichment.
Fernanda Stoffel,Fernanda Stoffel,Weslei de Oliveira Santana,Roselei Claudete Fontana,Jean Guilherme Novello Gregolon,Tarso B. L. Kist,Félix Gonçalves de Siqueira,Simone Mendonça,Marli Camassola +8 more
TL;DR: Grain flours colonized by macrofungi mycelia through SSC can enrich the nutritional value and the biological activity of the flours, which presents a potential for functional foods.
Journal ArticleDOI
Influence of pH and temperature on the production of polygalacturonases by Aspergillus fumigatus
TL;DR: Both polygalacturonases showed higher thermostability than that usually described in the literature for enzymes produced by other species of the genus Aspergillus, evidencing a potential of using these enzymes in industrial applications.
