Background Cellulose, the most abundant biopolymer on earth, is an alternative for fossil fuels as a renewable feedstock for the production of second-generation biofuels and other chemicals. The discovery of novel, highly efficient β-glucosidases remains as one of the major bottlenecks for cellulose degradation. In this context, the ascomycete Talaromyces amestolkiae, isolated from cereal sampl...

Abstract This paper reports on the preparation and electrochemical performance of chitin- chitin-cellulose-based hydrogel electrolytes. The materials were prepared by a casting solution technique using ionic liquid-based solvents. method chitin dissolution in liquid with assistance dimethyl sulfoxide co-solvent was investigated. obtained membranes soaked 1-M lithium sulfate aqueous solution. pr...

Organic materials have attracted considerable attention for thermoelectric (TE) applications. Given their potential as wearable power generators, there is an urgent need to develop organic TE that possess superior electronic properties well excellent mechanical and environmental stability. Here, we paper-based using the poly(3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS), graphen...

Cellulose is a biopolymer that has broad potential applications including in building insulation, and it was studied for its as filler material. A closed-cell polyurethane foam insulation formulation developed, cellulose filaments (CFs) were introduced at varying percentages. The viscosity morphology of the formulations studied, different properties, such water vapor permeability, reaction kine...

Typical construction materials and practices have a large ecological footprint. Many materials are energyintensive to produce, and construction and demolition debris constitutes a large percentage of U.S. landfill volume. Biocomposites are structural materials made from renewable resources that biodegrade in an anaerobic environment after their useful service life to produce a fuel or feedstock...

Chitin is a natural polysaccharide of major importance. This biopolymer is synthesized by an enormous number of living organisms; considering the amount of chitin produced annually in the world, it is the most abundant polymer after cellulose. The most important derivative of chitin is chitosan, obtained by partial deacetylation of chitin under alkaline conditions or by enzymatic hydrolysis. Ch...

Lignin is the second most abundant terrestrial biopolymer after cellulose. It is essential for the viability of vascular plants. Lignin precursors, the monolignols, are synthesized within the cytosol of the cell. Thereafter, these monomeric precursors are exported into the cell wall, where they are polymerized and integrated into the wall matrix. Accordingly, transport of monolignols across cel...

A new type of biopolymer-based heterogeneous catalyst, cellulose supported acidic ionic liquid (Cell-IL), which was developed earlier in our lab, has been found to be very effective for the regioselective synthesis of pyrazole based pyrido[2,3-d]pyrimidine-diones. Its regioselectivity was confirmed by (1)H NMR spectroscopy. All the newly synthesized compounds were characterized by LC-MS, (1)H N...

Currently, measuring enzyme activities in soils or other lignocellulose-based materials is technically feasible; this measurement is particularly suitable for evaluating soil processes of biopolymer (cellulose, hemicelluloses, lignin, chitin and others) degradation by microbes and for assessing cycling and mobilization of principal nutrients including nitrogen, phosphorus and sulfur. With some ...

Acid-catalyzed hydrolysis of glycosidic bonds is the most important degradation mechanism affecting cellulose-based materials. It results in decrease DP and loss original mechanical properties. The neutralization acidity therefore one efficient ways to hamper cellulosic artworks. However, case acidic strongly degraded artifacts, addition deacidification, a consolidation treatment must be perfor...
