Effect of pectinolitic enzymes on the physical properties of caja-manga (Spondi...
Umsza-Guez,Marcelo Andres; Rinaldi,Rebeca; Lago-Vanzela,Ellen Silva; Martin,Natalia; Silva,Roberto da; Gomes,Eleni; Thoméo,João CláudioCajá-manga, also known as golden apple and hog-plum, is an exotic fruit native from Îles de la Société (French Polynesia), which was first introduced in Brazil in 1985. The pulp of ripe fruit was treated with the commercial enzymatic pool and its effect was evaluated in terms of yield, as well as the physical properties viscosity, turbidity and color (L* values). Response surface methodology was used and three ...
Enzimas termoestáveis: fontes, produção e aplicação industrial
Gomes,Eleni; Guez,Marcelo Andrés Umsza; Martin,Natalia; Silva,Roberto daREVIEW: Living organisms encountered in hostile environments that are characterized by extreme temperatures rely on novel molecular mechanisms to enhance the thermal stability of their proteins, nucleic acids, lipids and cell membranes. Proteins isolated from thermophilic organisms usually exhibit higher intrinsic thermal stabilities than their counterparts isolated from mesophilic organisms. Although the molec...
Production and partial characterization of polygalacturonases produced by therm...
Freitas,Paula Mendes de; Martin,Natalia; Silva,Dênis; Silva,Roberto da; Gomes,EleniPolygalacturonases production by newly isolated Monascus sp N8 and Aspergillus sp N12 strains was carried out in solid-state fermentation using mixtures of wheat bran, sugar cane bagasse and orange bagasse as carbon sources. The maximal activity values of exo-polygalacturonases (exo-Pg) from Monascus sp and Aspergillus sp were obtained using wheat bran/sugar cane bagasse/orange bagasse mixture (6.6 U/mL) and wh...
Pectinase production by fungal strains in solid-state fermentation using agro-i...
Martin,Natalia; Souza,Simone Regina de; Silva,Roberto da; Gomes,EleniPectin lyase and polygalacturonase production by newly isolated fungal strains was carried out in solid-state fermentation. Moniliella SB9 and Penicillium sp EGC5 produced polygalcturonase (PG) and pectin lyase (PL) on mixture of orange bagasse, sugar cane bagasse and wheat bran as substrate. PG and PL produced by Moniliella presented optimum activity at pH 4.5 and 10.0 and at 55 and 45°C, respectively, while t...
