      Lignocellulosic biomass is recognized as a sustainable source of mixed sugars for fermentation to second generation biofuels and biomaterials [].Its resistance to enzymatic deconstruction, however, is a major bottleneck for the development of cost-effective biorefineries [].Currently, high enzyme loadings of cellulases are needed because of their low specific Cited by:   Biotechnological approaches to reduce or modify lignin in biomass crops are predicated on the assumption that it is the principal determinant of the recalcitrance of biomass to enzymatic digestion for biofuels production.

    Lignin is a heterogeneous, aromatic polymer and one of the main components of plant biomass. Current lignocellulosic biorefineries primarily focus on polysaccharide conversion from biomass, and separate and combust the residual lignin for heat and power.

Quantitative characterization of lignocellulosic biomass using surrogate mixtures and multivariate techniques Article in Bioresource Technology February with 74 Reads.

Introduction. Lignocellulosic biomass for biofuel production has attracted much attention because of its abundance and three major components of lignocellulosic biomass, cellulose, hemicellulose and lignin, could be candidates for further biological/chemical -generation ethanol, or bioethanol, for example, is being developed from Cited by: 4.

As interest in lignocellulosic biomass feedstocks for conversion into transportation fuels grows, the summative compositional analysis of biomass, or plant-derived material, becomes ever more important.

The sulfuric acid hydrolysis of biomass has been used to measure lignin and structural carbohydrate content for more than by: A common approach to measure the treatment intensity in LHW is the usage of the so-called severity factor, which was defined by Overend and Chornet: (1) R 0 = t exp T − where t is the residence time in [min] and T is the temperature in [°C].

Since R 0 depends on temperature and time, it can be used to measure the combined effect of both variables in a given by: Valorization of Biomass to Value-Added Commodities. Valorization of Biomass to Value-Added Commodities pp | Cite as.

Evaluation of Methods for the Analysis of Untreated and Processed Lignocellulosic Biomasses. Currently, the relatively high cost of enzymes such as glycoside hydrolases that catalyze cellulose hydrolysis represents a barrier to commercialization of a biorefinery capable of producing renewable transportable fuels such as ethanol from abundant lignocellulosic biomass.

Among the many families of glycoside hydrolases that catalyze cellulose and hemicellulose hydrolysis, Cited by: Lignocellulosic biomass, such as crop residue or grass, is the most sustainable biomass for producing bioenergy but it is also a very challenging substrate to Author: Pratima Bajpai.

The derivation of second-generation biofuels from non-edible biomass is viewed as crucial for establishing a sustainable bio-based economy for the future. The inertness of lignocellulosic biomass makes its breakdown for conversion into fuels and other compounds a challenge.

Abstract: Background: Lytic Polysaccharide Monooxygenases (LPMOs) are auxiliary accessory enzymes that act synergistically with cellulases and which are increasingly being used in secondgeneration Cited by: 2. Lytic polysaccharide monooxygenases (LPMOs) are able to cleave recalcitrant polysaccharides, such as cellulose, by oxidizing the C1 and/or C4 atoms.

The analysis of the resulting products requires a variety of analytical techniques. Up to now, these techniques mainly focused on the identification of non-oxidized and C1-oxidized oligosaccharides. Comparison of three existing methodologies for the quantitative analysis of the KGM content of the PKF, namely 3,5-dinitrosalicylic acid (3,5-DNS), phenol–sulphuric acid and enzymatic colorimetric assays; indicated that the 3,5-DNS colorimetric assay was the most reproducible and accurate method, with a linear correlation coefficient of   Pleurotus ostreatus is the second edible mushroom worldwide, and a model fungus for delignification applications, with the advantage of growing on woody and nonwoody feedstocks.

Its sequenced genome is available, and this gave us the opportunity to perform proteomic studies to identify the enzymes overproduced in lignocellulose cultures.

The improvement of the saccharification of rice straw is one of the strategies to reduce the sophisticated pretreatment that results in high cost and is unfriendly to the environment.
