Rapid and accurate determination of the lignin content of lignocellulosic biomass by solid-state NMR.
Biofuels and biomaterials, produced from lignocellulosic feedstock, require facile access to cellulose and hemicellulose to be competitive with petroleum processing and sugar-based fermentation. Physical-chemical barriers resulting from lignin complicates the hydrolysis biomass into fermentable sugars. Thus, the amount of lignin within a substrate is critical in determining biomass processing. ...
متن کاملChemical and Physicochemical Pretreatment of Lignocellulosic Biomass: A Review
Overcoming the recalcitrance (resistance of plant cell walls to deconstruction) of lignocellulosic biomass is a key step in the production of fuels and chemicals. The recalcitrance is due to the highly crystalline structure of cellulose which is embedded in a matrix of polymers-lignin and hemicellulose. The main goal of pretreatment is to overcome this recalcitrance, to separate the cellulose f...
متن کاملNondestructive, real-time determination and visualization of cellulose, hemicellulose and lignin by luminescent oligothiophenes
Enabling technologies for efficient use of the bio-based feedstock are crucial to the replacement of oil-based products. We investigated the feasibility of luminescent conjugated oligothiophenes (LCOs) for non-destructive, rapid detection and quality assessment of lignocellulosic components in complex biomass matrices. A cationic pentameric oligothiophene denoted p-HTEA (pentamer hydrogen thiop...
متن کاملPlant Biomass Characterization: Application of Solution- and Solid-State NMR Spectroscopy
Releasing fermentable sugars from lignocellulosic materials remains challenging due to resistance of plants to breakdown. A pretreatment stage is required to reduce this recalcitrance, which is considered to be the most intensive operating cost component of cellulosic ethanol production. There are different features that make plant biomass resistant to chemical and biological degradation, such ...
متن کاملDevelopment of a GC-MS Method for 5-hydroxymethylfurfural Determination in Wood after Steam-explosion Pretreatment
http://www.revistadechimie.ro 557 Woody biomass is the most abundant renewable resource and can be used for alternative energy sources and chemicals [1-4]. The major components of wood are: cellulose, hemicellulose and lignin [5-8]. Cellulose and hemicellulose could be chemical [9-10], biochemical [11], physic [12] and physico-chemical [13-15] depolymerized to sugars. Most of the chemical trans...
