Bacterial cellulose matrices to develop enzymatically active paper
(2020-01-31)
Article
Restricted access - publisher's policyThis work studies the suitability of bacterial cellulose (BC) matrices to prepare enzymatically active nanocomposites, in a framework of more environmentally friendly methodologies. After BC production and purification, ... -
Lignin particles for multifunctional membranes, antioxidative microfiltration, patterning and 3D structuring
(2019-11-08)
Article
Restricted access - publisher's policyWe introduce a new type of particle-based membrane based on the combination of lignin particles (LPs) and cellulose nanofibrils (CNF), the latter of which are introduced in small volume fractions to act as networking and ... -
Laccase/TEMPO-mediated bacterial cellulose functionalization: production of paper-silver nanoparticles composite with antimicrobial activity
(2019-01-01)
Article
Restricted access - publisher's policyBacterial cellulose (BC) was functionalized applying the Laccase/TEMPO oxidative treatment, leading to a five-fold increase of the concentration of carboxyl groups. Paper produced with this cellulose showed improved ... -
A straightforward bioprocess for a cleaner paper decolorization
(2019-07-17)
Article
Restricted access - publisher's policyA new biotechnological sequence for decolorizing red and black colored paper was developed to reduce the environmental impact of the chemicals used in paper recycling processes. Commercially available low-redox potential ... -
Assessing the enzymatic effects of cellulases and LPMO in improving mechanical fibrillation of cotton linters
(2019-06-26)
Article
Open AccessBackground: 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 ... -
Enhanced fully cellulose based forward and reverse blood typing assay
(2019-05-07)
Article
Open AccessThis study presents an enhanced paper-based analytical device (PAD) for forward and reverse group blood typing. The proposed PAD uses a novel methodology, which provides highly reliable results on a fully cellulose based ... -
Microbial cellulose from a komagataeibacter intermedius strain isolated from commercial wine vinegar
(2019-02-21)
Article
Open AccessIn this study a new bacterial cellulose (BC) producer isolated from commercial vinegar is identified as Komagataeibacter intermedius JF2 based on the examination of general taxonomical characteristics, 16S rDNA sequence ... -
Differential activity of lytic polysaccharide monooxygenases on celluloses of different crystallinity. Effectiveness in the sustainable production of cellulose nanofibrils
(2019-03-01)
Article
Open AccessA series of cellulosic substrates has been produced, treated with lytic polysaccharide monooxygenase (LPMO) from Streptomyces ambofaciens (SamLPMO10C), and analyzed by high performance anion exchange chromatography (HPAEC) ... -
Novel applications of nonwood cellulose for blood typing assays
(2018-10-03)
Article
Open AccessPaper-based microfluidics devices can create a new healthcare model. Cellulose is carbohydrate polymer biocompatible and hydrophilic. These characteristics enhance the development of user-friendly diagnostic devices, but ... -
Bacterial cellulose for increasing barrier properties of paper products
(2018-08-07)
Article
Open AccessBacterial cellulose was combined with wood cellulose papers in order to obtain biomaterials with increased barrier properties. For this purpose, different parameters were assessed: two producing bacterial strains ... -
Alternative chemo-enzymatic treatment for homogeneous and heterogeneous acetylation of wood fibers
(2018-07-18)
Article
Open AccessA new chemo-enzymatic treatment is proposed to produce cellulosic fibers suitable for heterogeneous- or homogeneous-phase acetylation. The procedure included enzymatic (laccase–violuric acid) lignin removal from the precursor ... -
Facilitating the selection of raw materials: evaluation of the effects of TCF and ECF bleaching sequences on different wood and non-wood pulps
(2018-06)
Article
Open AccessProperties of cellulosic raw materials are known to vary widely among different sources. The interest in the usage of non-conventional fibers makes necessary a better knowledge of the peculiarities of each source and their ...
