Cellulases play a key role in enzymatic routes for degradation of plant cell-wall polysaccharides into simple and economically-relevant sugars. However, their low performance on complex substrates reduced stability under industrial conditions remain the main obstacle large-scale production cellulose-derived products biofuels. Thus, this study novel cellulase with unusual catalytic properties from sugarcane soil metagenome (CelE1) was isolated characterized. The polypeptide deduced celE1 gene...
Abstract The integration of first‐ (1G) and second‐generation (2G) ethanol production by adding sugarcane juice or molasses to lignocellulosic hydrolysates offers the possibility overcome problem inhibitors (acetic acid, furfural, hydroxymethylfurfural phenolic compounds), add nutrients (such as salts, sugars nitrogen sources) fermentation medium, allowing higher titers. In this work, an 1G2G process was developed with hemicellulosic hydrolysate (HH) from a diluted sulfuric acid pretreatment...
Metagenomics has been widely employed for discovery of new enzymes and pathways to conversion lignocellulosic biomass fuels chemicals. In this context, the present study reports isolation, recombinant expression, biochemical structural characterization a novel endoxylanase family GH10 (SCXyl) identified from sugarcane soil metagenome. The SCXyl was highly active against xylan beechwood showed optimal enzyme activity at pH 6,0 45°C. crystal structure solved 2.75 Å resolution, revealing...
ABSTRACT First-generation ethanol (E1G) is based on the fermentation of sugars released from saccharine or starch sources, while second-generation (E2G) focused lignocellulosic feedstocks. During fractionation process to release hemicelluloses (mainly xylose), some inhibitor compounds are hindering fermentation. Thus, biggest challenge using hemicellulosic hydrolysate selecting strains and processes able efficiently ferment xylose tolerate inhibitors. With aim diluting inhibitors, sugarcane...
ABSTRACT Melle-boinot fermentation process can be used to increase the ethanol productivity in second-generation (2G). However, bacterial contamination result decreased production and sugars consumption. The available literature on microbial 2G at secretome level, interactions their impacts are scarce. In this context, cultivation of Spathaspora passalidarum was studied pure co-culture with Lactobacillus fermentum under conditions that mimic process. Glucose consumption by S. were not...
A redução nas taxas de transmissão vertical do HIV (TVHIV) é resultado da implementação medidas preventivas nos serviços no âmbito Sistema Único Saúde (SUS), incluindo cuidados pré-natal, profilaxias parto e inibição lactação. Identificar onde quando ocorrem falhas fundamental para adotar reparadoras evitar novos casos. Descrever as características das maternidades adotadas a prevenção TVHIV. O estudo utilizou questionário estruturado coleta dados, sendo enviado 1975 instituições com...
