Lignin is the second most abundant biopolymer on Earth, right after cellulose, with a highly complex chemical structure that hinders its possible utilizations. As a consequence, it is mostly burned as an inexpensive resource, generating green electricity or heat that in turn can be used for the deconstruction of biomass itself. Applications that utilize lignin in different manners are of great ...
a green and convenient method for the synthesis of 14-aryl-14h-dibenzo[a,i]xanthene-8,13-diones and spiro[dibenzo[a,i]-xanthene-14,3'-indoline]-2',8,13-triones in the presence of a catalytic amount of cellulose sulfuric acid (csa) as an efficient biopolymer-based catalyst under solvent-free conditions at 100 °c is described. the condensation reactions of β-naphtol, 2-hydroxynaphthalene-1,4-dion...
Cellulose is a natural biopolymer with the general (C6H10O5)n formula, which according to AWS A5.5 standard, more than 40wt% of coating of cellulosic electrodes is consisted of cellulose. In this study to evaluate the effect of cellulose type on the performance of E8010-P1 cellulosic electrode, equal amounts of two celluloses with the same commercial properties but produced by two different c...
Cellulose is the most abundant biopolymer on earth, recognized as the major component of plant biomass. The cellulolytic microorganisms were isolated from gut of earthworm (Eisenia foetida). Using Glycerol asparagine agar media, the organisms were identified as Actinomycetes sps.. The endoglucanase activity of the culture broth was determined during actinomycetes growth by measuring the release...
Structured biofoams have been prepared from the readily available renewable biopolymer xylan by employing an icetemplating technique, where the pore morphology of the material can be controlled by the solidification conditions and the molecular structure of the polysaccharide. Furthermore, reinforcement of these biodegradable foams using cellulose nanocrystals shows potential for strongly impro...
Introduction of Soft X-Ray Spectromicroscopy as an Advanced Technique for Plant Biopolymers Research
Soft X-ray absorption spectroscopy coupled with nano-scale microscopy has been widely used in material science, environmental science, and physical sciences. In this work, the advantages of soft X-ray absorption spectromicroscopy for plant biopolymer research were demonstrated by determining the chemical sensitivity of the technique to identify common plant biopolymers and to map the distributi...
The objective of this research was to develop novel cellulose acetate (biopolymer) composite materials with an excellent antimicrobial activity by embedding molybdenum trioxide particles with unique high specific surface area. High surface area molybdenum trioxide particles were prepared from freshly precipitated molybdenum trioxide dihydrate (MoO3 ·2H2 O) and subsequent calcination at 340°C un...
The amalgamation of polymer and pharmaceutical sciences led to the introduction of polymer in the design and development of drug delivery systems. Polymeric delivery systems are mainly intended to achieve controlled or sustained drug delivery. Polysaccharides fabricated into hydrophilic matrices remain popular biomaterials for controlled-release dosage forms and the most abundant naturally occu...
As the most abundant biopolymer on Earth, cellulose is a key structural component of the plant cell wall. Cellulose is produced at the plasma membrane by cellulose synthase (CesA) complexes (CSCs), which are assembled in the endomembrane system and trafficked to the plasma membrane. While several proteins that affect CesA activity have been identified, components that regulate CSC assembly and ...
Cellulose is the most abundant biopolymer in terrestrial ecosystems and is degraded by microbial communities in soils. However, relatively little is known about the diversity and function of soil prokaryotes that might participate in the overall degradation of this biopolymer. The active cellulolytic and saccharolytic Bacteria in an agricultural soil were evaluated by 16S rRNA (13)C-based stabl...
