Previous studies on the use of SO2 and CO2 as impregnating agent for sugar cane bagasse steam treatment showed comparative promising results concerning cellulose enzymatic hydrolysis low formation inhibitors furfural hydroxymethylfurfural at 205°C/15 min or 190°C/5 min. In present study materials pretreated aforementioned were analyzed by scanning transmission electron microscopy (SEM TEM), X-Ray Diffraction (XRD) Infrared (FTIR spectroscopy) aiming a better understanding structural chemical...
Abstract Background The conditions for steam pretreatment of sugar cane bagasse and leaves were studied using CO 2 as an impregnating agent. following investigated: time (5 to 15 min) temperature (190 220°C). was assessed in terms glucose xylose yields after enzymatic hydrolysis inhibitor formation (furfural hydroxymethylfurfural) the pretreatment. Results from SO agent used reference. For bagasse, highest yield (86.6% theoretical) obtained at 205°C min. (97.2% 220°C 5 reference...
The establishment of a bioeconomy era requires not only change production pattern, but also deep modernization the processes through implementation novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting commodities such biofuels other high added value chemicals. utilization renewable raw resources residues from agro-industries, their exploitation various uses applications technologies, particularly solid-state fermentation (SSF), are...
In Brazil, sugarcane biomass is generated in large amounts. Sugarcane bagasse and straw are considered as an important feedstock for renewable energy biorefinery. This paper aims to study the generation of monosaccharides (C5 C6) from via processing or mixtures both materials (bagasse:straw 3:1, 1:1 1:3). Samples were pretreated with sulfuric acid which resulted approximately 90% hemicellulose solubilization, corresponding around 58 g L− 1 xylose. Pretreated showed greater susceptibility...
Biocatalysis—specifically the use of immobilized lipases—has been proposed as a greener alternative for ester production. Several critical challenges, such high cost biocatalysts, are delaying industrial implementation biocatalysis. Moreover, short-chain synthesis, strong inhibition/inactivation potential acids and alcohols on lipases leads to long reaction cycles and/or need organic solvents overcome limitations solvent-free systems and, consequently, decrease in product concentrations....
This work studied the potential use of horseradish peroxidase (HRP) in decolorization following textile dyes: Drimarene Blue X-3LR (DMBLR), X-BLN (DMBBLN), Rubinol (DMR), and CL-R (RBBR). Dyes were individually tested reaction media containing 120 mg⋅L -1 , considering parameters: temperature (20–45 ° C), H 2 O concentration (0–4.44 mmol⋅L ), time (5 minutes, 1 24 h). The conditions: 35 C, 0.55 1h, provided best set results color removal for DMBLR (99%), DMBBLN (77%), DMR (94%), RBBR (97%)....
The change of manually harvested sugarcane, after crop burning, to mechanically harvest green cane allows straw and bagasse be available for further processing via either chemical or biochemical routes, which increases the sector’s energy efficiency. In this study, sugarcane bagasse, a bagasse-straw 1:1 mixture were subjected, under comparative conditions, hydrothermal pretreatment at 195°C 10 minutes enzymatic conversion. We evaluated individual responses three different materials regarding...
Atrazine is the most common herbicide applied in crops of economic relevance, such as sugar cane, soybean, and corn. its derivatives desethylatrazine (DEA) desisopropylatrazine (DIA) are toxic to environment, affecting animal human health. Thus, this study aimed evaluate degradation atrazine by fungus Pleurotus ostreatus INCQS 40310, well potential enzymes involved process. P. 40310 was able degrade (82%), DEA (71%), DIA (56%) over 22 days fungal cultivation. Proteomic analysis indicated...
