Xanthomonas campestris expansin-like X domain is a structurally disordered beta-sheet macromolecule capable of synergistically enhancing enzymatic efficiency of cellulose hydrolysis
(Springer, 2015-12-01)
Objectives To biochemically characterize an expansin-like X protein domain from Xanthomonas campestris (XcEXLX1) and to study its synergy with cellulases in cellulose depolymerization. Results The protein was purified using ...
Improving cellulosic ethanol production using ozonolysis and acid as a sugarcane biomass pretreatment in mild conditions
(2021-02-01)
The efficiency of unpressurized ozonolysis (O) and acid washing (A) was investigated as a simple pretreatment procedure to depolymerize sugarcane biomass for posterior enzymatic hydrolysis and alcoholic fermentation to ...
Despolimerização de Polietilenotereftalato (PET) mediada por fungos filamentosos
(Universidade Estadual Paulista (Unesp), 2018-10-08)
As características de recalcitrância e insolubilidade em água tornam a disposição final de polímeros, um grande problema para sociedade moderna. Estima-se que em 30 anos, a quantidade de garrafas de polietilenotereftalato ...
Cell wall-related enzymatic activities and transcriptional profiles in four strawberry (Fragaria x ananassa) cultivars during fruit development and ripening
(2018)
Fruit softening during ripening is mainly a consequence of solubilization and depolymerization of cell wall components mediated by the action of a complex set of enzymes and proteins. In the present work, we performed a ...
Enhanced rates of enzymatic saccharification and catalytic synthesis of biofuel substrates in gelatinized cellulose generated by trifluoroacetic acid
(BioMed Central, 2017)
Abstract
Background
The crystallinity of cellulose is a principal factor limiting the efficient hydrolysis of biomass to fermentable sugars or direct catalytic conversion ...
Produção, propriedades e aplicações de oligossacarídeos
(Universidade Estadual de Londrina (UEL), 2011-01-01)
Oligosaccharides participate in the formation of dietary fiber and are mainly used as prebiotic agents. This review presents ways of obtaining these sugars, which can be produced by synthesis (chemical or enzymatic), or ...
