Development of efficient methods for production renewable fuels from lignocellulosic biomass is necessary to maximize yields and reduce operating costs. One the main challenges industrial application conversion process high costs cellulolytic enzymes. Recycling enzymes may present a potential solution alleviate this problem. In study associated with insoluble fraction were recycled after enzymatic hydrolysis pretreated sugarcane bagasse, utilizing different processing conditions, enzyme...
Blending of the enzyme extracts produced by different fungi can result in favorable synergetic enhancement blend with regards to main cellulase activities, as well inclusion accessory enzymes that may not be abundant predominantly producing fungi. The Chrysoporthe cubensis:Penicillium pinophilum 50:50 (v/v) herein presented good synergy, especially for FPase and endoglucanase activities which were 76% 48% greater than theoretical, respectively. This was applied sugarcane bagasse previously...
Biomass enzymatic hydrolysis depends on the pretreatment methods employed, composition of initial feedstock and enzyme cocktail used to release sugars for subsequent fermentation into ethanol. In this study, sugarcane bagasse was pretreated with 1% H2SO4 NaOH biomass saccharification performed 8% solids loading using 10 FPase units/g extract from Chrysoporthe cubensis three commercial cocktails a comparative study. Overall, best glucose xylose obtained alkaline bagasse. The C. promoted...
An intracellular β-glucosidase from Debaryomyceshansenii UFV-1 was produced in an YP medium with cellobiose as the carbon source. This enzyme purified, characterised and presented a Mr of 65.15kDa. Yeast cells containing were immobilised calcium alginate. The free optima values pH temperature 6.0 45°C 5.5 50°C, respectively. maintained 62% 47% its original activity after 90days at 4°C 15days room temperature, immobilisation process resulted higher thermostability 45 50°C. Soy molasses...
Different lignocellulosic biomasses are found worldwide and each country has its own important industrial crop that can be converted into high-value products, such as ethanol. Therefore, evaluation of new to used in biorefineries is decrease the dependence on non-renewable resources guarantee sustainable development. This work evaluated Brachiaria brizantha, a grass commonly animal forage, standard biomass for 2G-ethanol, sugarcane bagasse. The chemical compositions both were determined...
