1. New Detector Based on Composite of Carbon Nanotubes with Nanoparticles of Cobalt Oxide for Carbohydrates Analysis by HPLC with Reverse Pulsed Amperometric Detection
This work aims to present an alternative detector for the determination of arabinose, galactose, glucose and xylose in hydrolyzed sugarcane bagasse. The detector was developed using an electrode modified with multi-walled carbon nanotubes containing cobalt oxide nanoparticles (GCE/MWCNT/CoOOH) applied in high-performance liquid chromatography (HPLC) with rev

2. The potential of the newly isolated thermotolerant yeast Pichia kudriavzevii RZ8-1 for high-temperature ethanol production
Abstract High potential, thermotolerant, ethanol-producing yeasts were successfully isolated in this study. Based on molecular identification and phylogenetic analysis, the isolated thermotolerant yeasts were clustered in the genera of Pichia kudriavzevii, Candida tropicalis, Candida orthopsilosis, Candida glabrata and Kodamea ohmeri. A comparative study of

3. 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)

4. Ethanol Production from Sugarcane Bagasse Using Phosphoric Acid-Catalyzed Steam Explosion
The steam explosion was carried out in the absence (autohydrolysis) and presence of phosphoric acid to evaluate the effects of temperature (180 and 210 °C), acid concentration (0 and 19 mg g-1, dry basis) and pretreatment time (5 and 10 min) on the structure and reactivity of sugarcane bagasse. Glucan recovery was used as the main response factor for pretre

5. Thermotolerant and mesophylic fungi from sugarcane bagasse and their prospection for biomass-degrading enzyme production
Nineteen fungi and seven yeast strains were isolated from sugarcane bagasse piles from an alcohol plant located at Brazilian Cerrado and identified up to species level on the basis of the gene sequencing of 5.8S-ITS and 26S ribosomal DNA regions. Four species were identified:

6. INFLUENCE OF SOLID MOISTURE AND BED HEIGHT ON CULTIVATION OF Aspergillus niger FROM SUGARCANE BAGASSE WITH VINASSE
AbstractSolid-state cultivation (SSC) may be defined as growth of microorganisms on a solid support impregnated or not with a nutrient solution in near absence of free-water conditions. The use of sugarcane bagasse as a support for SSC usually demands that the particles are impregnated and moistened with nutrient solution. Vinasse is the main wastewater of e

7. EVALUATION OF COMPOSITION, CHARACTERIZATION AND ENZYMATIC HYDROLYSIS OF PRETREATED SUGAR CANE BAGASSE
Abstract Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and

8. Produção de ácido lático a partir do bagaço da cana de açúcar / Production of lactic acid from sugar cane bagasse
Production of chemical compounds from lignocellulose residues has attracted attention of actual world society. The search for productive alternatives fossil fuels non-dependent, the use of renewable resources and sustainability are the main reasons. In this work, lactic acid production by fermentation of sugars obtained from sugarcane bagasse, essentially gl

9. Otimização do pré-tratamento com peróxido de hidrogênio alcalino a alta concentração de sólidos para a hidrólise enzimática de bagaço de cana-de-açúcar / Optimization of the pre-treatment with alkaline hydrogen peroxide at high solids concentration for the enzymatic hydrolysis of sugarcane bagasse
In this work the performance of the pretreatment of sugarcane bagasse with high solids concentration using alkaline hydrogen peroxide was evaluated. The objective was to increase the solids concentration in the pretreatment in relation to previous work (RABELO, 2007; GARCIA, 2009). Initially, a 23 factorial design was performed to evaluate the influence of t

10. Enzyme loading dependence of cellulose hydrolysis of sugarcane bagasse
The enzymatic hydrolysis of steam-pretreated sugarcane bagasse, either delignified or non-delignified, was studied as a function of enzyme loading. Hydrolysis experiments were carried out using five enzyme loadings (2.5 to 20 FPU/g cellulose) and the concentration of solids was 2% for both materials. Alkaline delignification improved cellulose hydrolysis by

11. Hidrólise ácida de bagaço de cana-de-açúcar: estudo cinético de sacarificação de celulose para produção de etanol / Acid hydrolysis of sugarcane bagasse: kinetic study of cellulose saccharification for ethanol production
O bagaço de cana-de-açúcar é um resíduo gerado no processo de produção de açúcar e álcool pelas usinas. O histórico de uso desse material aponta para a queima visando à produção de vapor e energia para o processo. As necessidades ambientais e econômicas ligadas tanto à emissão de gases estufa quanto as áreas agricultáveis apontam para um m

12. Estudo da influência de pré-tratamentos de dois resíduos lignocelulósicos (bagaço do pedúnculo de caju e casca de coco) utilizados como substrato na indução à síntese de enzimas celulolíticas
Nowadays generation ethanol second, that t is obtained from fermentation of sugars of hydrolyses of cellulose, is gaining attention worldwide as a viable alternative to petroleum mainly for being a renewable resource. The increase of first generation ethanol production i.e. that obtained from sugar-cane molasses could lead to a reduction of lands sustainable
