Purification and Characterization of the alpha-Glucosidase Produced by Thermophilic Fungus Thermoascus aurantiacus CBMAI 756
(Journal of Microbiology, 2010-08-01) [Artigo]
An alpha-glucosidase enzyme produced by the fungus Thermoascus aurantiacus CBMAI 756 was purified by ultra filtration, ammonium sulphate precipitation, and chromatography using Q Sepharose, Sephacryl S-200, and Superose ...
Production and characterization of a milk-clotting protease in the crude enzymatic extract from the newly isolated Thermomucor indicae-seudaticae N31 (Milk-clotting protease from the newly isolated Thermomucor indicae-seudaticae N31)
(Food Chemistry, 2010-05-01) [Artigo]
Microbial rennet-like milk-clotting enzymes are aspartic proteinases that catalyze milk coagulation. substituting calf rennet. Crude enzymatic extract produced by the thermophilic fungus, Thermomucor indicae-seudaticae ...
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 ...
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 ...
Pretreatment of sugarcane bagasse with microwaves irradiation and its effects on the structure and on enzymatic hydrolysis
(Applied Energy, 2014-06-01) [Artigo]
This paper refers to the new proposal of pre-treatment of sugarcane bagasse with microwave associated to glycerol, seeking greater release of fermentable sugars during enzymatic hydrolysis. The residue was subjected to ...
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 ...
A Novel beta-Glucosidase from Sporidiobolus pararoseus: Characterization and Application in Winemaking
(Journal of Food Science, 2011-09-01) [Artigo]
For the first time, the production of an extracellular beta-glucosidase (Sp-beta-gl) by a Sporidiobolus pararoseus yeast strain is reported. The Sp-beta-gl activity was quantified, characterized, and assessed for its ...
Ozonolysis applied to lignocellulosic biomass
(Bioethanol and Beyond: Advances in Production Process and Future Directions, 2018-01-01) [Capítulo de livro]
Lignocellulosic biomass produced by several agroindustrial processes has become the most important source of green carbon able to integrate the development of a mode of production based on the biorefinery concept. The ...
Modulation of the activity and selectivity of the immobilized lipases by surfactants and solvents
(Biochemical Engineering Journal, 2015) [Artigo]
Most of lipases are in equilibrium between a majority inactive closed form and a minority active open form in aqueous media. Perhaps, a certain stabilization of these open forms of lipases could be achieved in the presence ...
