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
Restricted access - publisher's policyThis 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
Restricted access - publisher's policyIn 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
Restricted access - publisher's policyA 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 ... -
Antioxidant activity of xylooligosaccharides produced from glucuronoxylan by Xyn10A and Xyn30D xylanases and eucalyptus autohydrolysates
(2018-08-15)
Article
Open AccessAntioxidant activity of xylooligosaccharides (XOS) released from beechwood and birchwood glucuronoxylans by two different xylanases, one from family GH10 (Xyn10A) and another from family GH30 (Xyn30D) was examined. The ... -
Particulate coatings via evaporation-induced self-assembly of polydisperse colloidal lignin on solid interfaces
(2018-05-02)
Article
Restricted access - publisher's policyPolydisperse smooth and spherical biocolloidal particles were suspended in aqueous media and allowed to consolidate via evaporation-induced self-assembly. The stratification of the particles at the solid–air interface was ...
