(Journal of Agricultural and Food Chemistry, 2011-12-28) [Artigo]
The aim of this study was the detailed characterization of the phenolic composition and the determination of the antioxidant activity of the Bora grape (Vitis labrusca) cultivated in South Brazil. The edible parts of Bora ...
Evaluation of the use of Syzygium cumini fruit extract as an antioxidant additive in orange juice and its sensorial impact
(International Journal of Food Sciences and Nutrition, 2012-05-01) [Artigo]
This work is an exploratory study of the possibility of promoting the consumption of Syzygium cumini fruit by adding its extract to orange juice making good use of its functional (antioxidant) properties. S. cumini fruit ...
Influence of ozonolysis time during sugarcane pretreatment: Effects on the fiber and enzymatic saccharification
(Bioresource Technology, 2017-01-01) [Artigo]
Modifications in sugarcane bagasse (SCB) from ozonolysis (O) NaOH (B) and ultrasound (U) (OBU) treatment for cellulosic ethanol production by enzymatic hydrolysis, were evaluated when increasing the exposure time of SCB ...
Temperature dependent cellulase adsorption on lignin from sugarcane bagasse
(Bioresource Technology, 2018-03-01) [Artigo]
Extents of adsorption of cellulolytic enzymes on lignin, derived from sugarcane bagasse, were an inverse function of incubation temperature and varied with type of lignin extraction. At 45 °C, lignin derived from acid ...
Mixed metal oxides from sucrose and cornstarch templated hydrotalcite-like LDHs as catalysts for ethyl biodiesel synthesis
(Applied Catalysis A: General, 2017-01-01) [Artigo]
Sucrose and cornstarch were used as organic templates in the synthesis of hydrotalcite-like layered double hydroxides (LDHs) prepared by the coprecipitation with partial replacement of Mg by Zn, and Al by Fe. Non-template ...
Influence of Different Substrates on the Production of a Mutant Thermostable Glucoamylase in Submerged Fermentation
(Applied Biochemistry and Biotechnology, 2011-01-01) [Artigo]
Three mutations, Ser54 -> Pro, Thr314 -> Ala, and His415 -> Tyr, were identified in Aspergillus awamori glucoamylase gene expressed by Saccharomyces cerevisiae. The mutant glucoamylase (GA) was substantially more thermostable ...
