Influência da concentração de biomassa na produção de etanol celulósico e caracterização de uma β-glucanase de kluyveromyces marxianus
… obtidas viimostraram alta similaridade com β-1,3 glucanases fúngicas. Além disto, foi medida a atividade hidrolitica desta enzima sobre a parede celular de leveduras. Os resultados mostram que a enzima possui um potencial para aplicação na produção de β-glucanos solúveis ou para preparação de …

Characterization of an alkalophilic Bacillus brevis isolate with respect to its endo-(1,3-1,4)-β-glucanase gene, protein hyperproduction and the degS-degU operon
… strains. A gene coding for an endo(1,3- 1,4 )-.8-glucanase (or lichenase) was cloned from B. brevis Alk 36 and expressed in Escherichia coli. The nucleotide sequence of this gene was determined and found to encode a protein of 252 amino acid residues. The amino acid sequence of the B. brevis …

Evaluation of the precision-fed rooster assay for detecting effects of exogenous carbohydrases and adaptation diet on true metabolizable energy and cecal microbial ecology, short-chain fatty acid profile, and enzyme activity
… while Experiment 2 evaluated two levels of a β-glucanase and xylanase on TMEn of pearled barley and rye diets, respectively. Two levels of a multi-carbohydrase combination were also evaluated for both grains. In both experiments, Single Comb White Leghorn roosters were fasted for 26 h and then …

Use of Bacillus subtilis starter cultures during red sorghum malting
… and the biocontrol steeping effect on β-glucanase activities are discussed. The effect of the biocontrol treatment and that of phytohormones produced by the bacterial strain used on the synthesis of specific red sorghum enzymes are elucidated. Gibberellic acid and abscisic acid diffusion …

Effects of exogenous enzymes alone or in combination with oligosaccharides on utilization of total dietary fiber, fermentation, growth performance, and health of weanling and growing pigs
… of a novel combination of xylanase and β-glucanase in diets for growing pigs increases the apparent total tract digestibility (ATTD) of gross energy and TDF, and therefore, increase metabolizable energy (ME) in high fiber diets for pigs was tested. Results indicated that pigs fed the high …

Process-induced changes on the functionality of oat β-glucan evaluated using a gastrointestinal simulation model
… prepared with hydrolysed β-glucan extracts or β-glucanase treatment. This study concludes that optimizing the process parameters and minimizing the enzymatic degradation of β-glucan during processing is crucial for enhancing extractability of β-glucan and maintaining β-glucan with optimal …
