Effects of P-Coumarate 3-Hydroxylase Downregulation on the Compositional and Structural Characteristics of Lignin and Hemicelluloses in Poplar Wood (Populus alba × Populus glandulosa)

Frontiers in Bioengineering and Biotechnology, 2021
Elucidating the chemical and structural characteristics of hemicelluloses and lignin in the p-coumarate 3-hydroxylase (C3H) down-regulated poplar wood will be beneficial to the upstream gene validation and downstream biomass conversion of this kind of ...

Chemical characterization of black poplar (Populus nigra L.) sawdust hemicelluloses esterified with acyl chlorides

Turkish Journal of Forestry, 2021
In the present study, hemicelluloses were isolated from black poplar (Populus nigra L.) sawdust, which is generated by the wood industry in large quantities as lignocellulosic waste. The monosaccharide composition of hemicelluloses was determined by gas

Pretreatment of Hazelnut Shells as a Key Strategy for the Solubilization and Valorization of Hemicelluloses into Bioactive Compounds

Agronomy, 2020
Hazelnut industries generate a large amount of byproducts. Among them, waste hazelnut shells (which account for about 50% of the nut weight), are potential raw materials to produce value added products.

Structural and Nutritional Peculiarities Related to Lifespan Differences on Four Lopesia Induced Bivalve-Shaped Galls on the Single Super-Host Mimosa gemmulata

Frontiers in Plant Science, 2021
Super-host plants are elegant models to evaluate the peculiarities of gall structural and nutritional profiles due to the stimuli of distinct gall inducers in temporal and spatial perspectives. Galls induced by congeneric insects, Lopesia spp.

Lower oxidative damage and cell wall loosening, mediated or not by auxin, as part of the tolerance mechanism of Paubrasilia echinata morphotypes in the shade and full sun

Acta Botânica Brasílica, 2022
Paubrasilia echinata presents three morphotypes that differ from each other in leaf morphology (small morphotype-SM, medium morphotype-MM, and large morphotype-LM) with indications of divergence between them regarding irradiance tolerance.

Electrokinetic properties of chemically modified jute fabrics [PDF]

Journal of the Serbian Chemical Society, 2020
In this work, the electrokinetic properties of alkali and oxidatively modified jute fabrics were studied. In contrast to the control fabric, chemically modified jute fabrics had a small positive zeta potential in the basic pH range, which could be ...

Fractionation of Waste MDF by Steam Refining

Molecules, 2020
In view of the expected increase in available waste medium-density fiberboard (MDF) and the current insufficient and unsatisfactory disposal capacities, efficient ways of recycling the waste material need to be developed.

Compression of Biomass Substances—A Study on Springback Effects and Color Formation in Pellet Manufacture

Applied Sciences, 2019
In order to increase the use of a variated raw material base for pellet production with a maintained density level, knowledge of the biomaterials’ ability to counteract any springback effects is essential. In this study, the springback effects were

Contribution of cell wall modifying enzymes on the texture of fleshy fruits: The example of apple [PDF]

Journal of the Serbian Chemical Society, 2013
Cell walls consist of polysaccharide assemblies (pectin, hemicelluloses and cellulose), whose structure and interactions vary depending on fruit genetic, and its stage and conditions of development.

Comprehensive Analysis of Foulants in an Ultrafiltration Membrane Used for the Treatment of Bleach Plant Effluent in a Sulfite Pulp Mill

Membranes, 2021
Fouling is a major obstacle in the introduction of membrane processes in new applications in the pulping industry. Due to the complex nature of the feed solutions, complementary analysis methods are usually needed to identify the substances involved ...
