1. Optimization of Alkaline, Acidic, Ionic Liquid and Oxidative Pretreatments for Coconut Waste Conversion into Fermentable Sugars
Cocos nucifera L. is a palm tree of paramount importance in the food and chemistry industries, although over 50% of its biomass is discarded as waste. The aim of the study is to investigate different pretreatments in to coconut husks (CH), based on acid, alkaline, ionic liquid (IL), and peroxidative, in order to produce fermentable sugars. Severity factors w

7. Partial-hydrothermal hydrolysis is an effective way to recover bioactives from turmeric wastes
Abstract Partial-hydrothermal hydrolysis using pressurized hot water was applied in waste turmeric, derived from extraction processes that employed supercritical and pressurized fluids, as a sustainable alternative for the recovery of bioactive constituents from this material. The reaction products consisted of a liquid extract of fermentable sugars and a so

8. Pretreatments and enzymatic hydrolysis of sugarcane bagasse aiming at the enhancement of the yield of glucose and xylose
ABSTRACT This work studied the enzymatic hydrolysis of sugarcane bagasse aiming at the production of glucose and xylose. The bagasse was subjected to two different pretreatments: combined acid and alkalinepretreatment and hydrogen peroxidepretreatment. The enzymatic hydrolysis was optimized and a kinetic study was carried out in a stirred tank reactor (STR)

9. DESAFIOS RELACIONADOS À PRODUÇÃO E APLICAÇÃO DAS ENZIMAS CELULOLÍTICAS NA HIDRÓLISE DA BIOMASSA LIGNOCELULÓSICA
The second generation (2G) ethanol obtained from lignocellulosic biomass has been considered as a potential alternative source of energy for the transportation sector. However, the technologies to convert lignocellulose into fermentable sugars still face several challenges. One of the major challenges of this process is related to the cost of the cellulolyti

10. EQUILÍBRIO QUÍMICO E CINÉTICA ENZIMÁTICA DA INTERAÇÃO DE α-AMILASE COM COMPOSTOS FENÓLICOS ENCONTRADOS EM CERVEJA
α-amylase is a key enzyme in the production of beer due to the breakdown of starch into fermentable sugars. During the preparation of the brewing mash, the enzyme can be affected by polyphenols present in the mixture. Our aim was to evaluate the kinetics and equilibrium of the interaction of α-amylase with some polyphenols (chlorogenic, caffeic, ferulic ac

11. Ethanol production in Brazil: a bridge between science and industry
ABSTRACT In the last 40 years, several scientific and technological advances in microbiology of the fermentation have greatly contributed to evolution of the ethanol industry in Brazil. These contributions have increased our view and comprehension about fermentations in the first and, more recently, second-generation ethanol. Nowadays, new technologies are a

12. Utilization of residue from cassava starch processing for production of fermentable sugar by enzymatic hydrolysis
Abstract The aim of this study was to characterize and perform enzymatic hydrolysis of cassava peeling residue (peel and inner peel), mainly composed of peels and small pieces. Residue was sanitized, dried at 55 °C for 24 hours and ground. The obtained flour showed pH of 4.85; 72.53 g 100 g–1 moisture; 5.18 mL 1M NaOH 100 g–1 acidity; 60.68 g 100 g–1
