“…1). The xylose that is recovered is a valuable carbon source for biological conversions—for example, with pentose-fermenting yeast and biocatalysts [4, 54]. The main impurity in the hemicellulose product stream was the lignin that was solubilized by STEX (Fig.…”

“…In the prehydrolysis-Kraft process, a prehydrolysis step extracts the hemicelluloses prior to Kraft pulping [3]. Apart from dissolving pulp, the value proposition of the process includes valorization of the hemicellulosic monomers and oligomers that are recovered from the prehydrolysis liquid [4] and Kraft lignin [5, 6]. However, covalently bonded sulfur in lignin represents a major drawback, because it hinders the catalytic upgrading and refining of lignin [7].…”

“…Different agri-basedmaterials often contain about 20-30% hemicelluloses. Because they are edible, biodegradable, and environmentally friendly, there has been increasing interest in using hemicelluloses for a variety of applications (Hansen & Plackett, 2008;Christopher, 2012). Two of the biopolymers in the hemicellulose family are galactomannans and xyloglucans.…”

“…O ácido lático é amplamente sintetizado industrialmente por via química, porém o procedimento leva à geração de dois isômeros, sendo requerida uma etapa de separação que acarreta em aumento dos custos do processo. A produção desse ácido a partir da fração de hemicelulose da biomassa representa uma vantagem nesse quesito, já que apenas um isômero é obtido ao final do processo (Christopher, 2012;Naidu et al, 2018). Já o composto furfural pode ser obtido a partir da hidrólise ácida da xilana e subsequente desidratação do monômero formado.…”

“…Já o composto furfural pode ser obtido a partir da hidrólise ácida da xilana e subsequente desidratação do monômero formado. A produção desse bioproduto, realizada somente a partir de biomassa lignocelulósica, é estimada em cerca de 200.000 toneladas por ano e é voltada principalmente para utilização como aditivo em tintas, adesivos e aromatizantes (Christopher, 2012;Naidu et al, 2018).…”
