Summary
This summary is machine-generated.Water-soluble products from agricultural byproducts, like feruloylated arabinoxylans and lignin-carbohydrate complexes (LCCs), can be incorporated into paper fibers. This modification enhances paper properties, showing potential for sustainable brown tissue paper production.
Area Of Science
- Biomass valorization and biorefinery applications.
- Sustainable materials science and paper product modification.
Background
- Biorefineries can generate water-soluble products from biomass.
- These products have potential applications but are underexplored in paper modification.
- Agricultural byproducts like corn stover and sugarcane bagasse are abundant resources.
Purpose Of The Study
- To investigate the incorporation of water-soluble biomass products into eucalyptus kraft pulp fibers.
- To evaluate the impact of these modifications on paper properties.
- To explore novel strategies for utilizing agricultural byproducts in papermaking.
Main Methods
- Extraction of water-soluble products from pretreated corn stover and sugarcane bagasse using xylanase.
- Incorporation of these products into pulp fibers via laccase-mediated reactions.
- Characterization of modified fibers and paper sheets using contact angle measurements and X-ray photoelectron spectroscopy.
Main Results
- Water-soluble products, rich in feruloylated arabinoxylans and lignin-carbohydrate complexes (LCCs), were successfully extracted.
- Up to 15.4 g of water-soluble products per 100 g of pulp were incorporated, with highest levels from ball-milled sugarcane bagasse.
- Modified paper sheets showed decreased water contact angles and increased carboxyl/ester groups, indicating successful xylan and LCC incorporation.
Conclusions
- Water-soluble products from biomass can be effectively incorporated into paper fibers, enhancing their properties.
- This approach offers a sustainable route for producing more wettable paper products, such as brown tissue paper.
- The study demonstrates novel strategies for valorizing agricultural byproducts within the biorefinery concept.

Wood products encompass a broad range of materials crafted from wood strands, veneers, lumber, and even waste wood-like shreds, designed for both structural and nonstructural purposes. Various specialized wood products have been developed to enhance strength, durability, and versatility in building applications.
Glue-laminated wood, often referred to as glulam, combines multiple smaller pieces of dimensional lumber using adhesives to form a single, larger piece. Cross-laminated timber consists...
Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
Lumber is derived from logs which are harvested, debarked, and processed into long pieces with a rectangular cross-section. The transformation of logs into lumber involves multiple steps, beginning with an automated saw that slices the log into slabs. These slabs are then transported via a conveyor belt to smaller saws, where they are cut into square-edged pieces of specific widths.
Initially, the surfaces of these lumber pieces are rough, and their dimensions may vary slightly from one end to...
