A novel enzymatic approach to nanocrystalline cellulose preparation
(2018-06-01)
Article
Accés obertIn this work, conditions for an enzymatic pretreatment prior to NCC isolation from cotton linter were assessed. Different cellulase doses and reaction times were studied within an experimental design and NCC were obtained. ... -
Assessing the enzymatic effects of cellulases and LPMO in improving mechanical fibrillation of cotton linters
(2019-06-26)
Article
Accés obertBackground: The increasing interest in replacing petroleum-based products by more sustainable materials in the packaging sector gives relevance to cellulose as a biodegradable natural resource. Moreover, its properties can ... -
Endoglucanase treatments for improving pulp reactivity in biobleached and commercial dissolving pulps
(2015)
Comunicació de congrés
Accés restringit per política de l'editorialIn this study, a bleached commercial dissolving pulp and a TCF sulphite pulp, bleached at the laboratory scale with a laccase–violuric acid system and complemented with a pressurized hydrogen peroxide stage (LVAPO), were ... -
Increasing yield of nanocrystalline cellulose preparation process by a cellulase pretreatment
(2015-06-09)
Article
Accés obertIn this work the introduction of a cellulase treatment prior to NCC isolation was assessed. NCC was produced using sulfuric acid at two different concentrations (62 and 64% wt.). The effect of pore size for filtration step ... -
Optimization of sulfuric acid hydrolysis conditions for preparation of nanocrystalline cellulose from enzymatically pretreated fibers
(2016-03-22)
Article
Accés obertNCC preparation using sulfuric acid hydrolysis from cellulase pretreated fibers was optimized in order to obtain the highest possible yield with 62% and 65% wt. sulfuric acid throughout two statistical plans. At optimal ...
