“…It contains various monosaccharide subunits to form xylans, xyloglucan, mannans and glucomannans, and others (McKendry, 2002). The DP of hemicelluloses is in the range of 100-200 units (Mota et al, 2018), which is much lower than that of cellulose, but it can present a high degree of more or less complex substitutions. Hemicellulose is amorphous, with little physical strength.…”

Lignocellulosic Biomass: Understanding Recalcitrance and Predicting Hydrolysis

Lignocellulosic biomass (LB) is an abundant and renewable resource from plants mainly composed of polysaccharides (cellulose and hemicelluloses) and an aromatic polymer (lignin). LB has a high potential as an alternative to fossil resources to produce second-generation biofuels and biosourced chemicals and materials without compromising global food security. One of the major limitations to LB valorisation is its recalcitrance to enzymatic hydrolysis caused by the heterogeneous multi-scale structure of plant cell walls. Factors affecting LB recalcitrance are strongly interconnected and difficult to dissociate. They can be divided into structural factors (cellulose specific surface area, cellulose crystallinity, degree of polymerization, pore size and volume) and chemical factors (composition and content in lignin, hemicelluloses, acetyl groups). Goal of this review is to propose an up-to-date survey of the relative impact of chemical and structural factors on biomass recalcitrance and of the most advanced techniques to evaluate these factors. Also, recent spectral and water-related measurements accurately predicting hydrolysis are presented. Overall, combination of relevant factors and specific measurements gathering simultaneously structural and chemical information should help to develop robust and efficient LB conversion processes into bioproducts.

“…Additional structural heterogeneity comes from the radical biosynthesis of lignin, not described in this review, but widely described in the literature [12,20]. The driving force for the synthesis of lignin is the formation of monolignol radicals, which have several resonance structures leading to the formation of several different C-O and/or C-C linkages [21][22][23] (see potential model structures in Figure 2). Due to the complexity, heterogeneity, and variety that is present in lignin, elucidating its structure and associated properties is a nontrivial task [24].…”

“…The complexity of carbohydrate Copyright © 2020 Universitas Sebelas Maret polymers and their cross-linking with lignin require a complex set of enzymes to allow polysaccharide access and release fermentable sugars. Lignocellulose basically consists of plant cell wall components (Mota et al, 2018). In contrast, the two fungi alone had no effect on the components of weed growth, i.e., weeds fresh and dry weights, when compared to control (Table 3).…”

Weeds are a major problem in crop cultivation, either in food crops, horticulture, plantations or forests and cause a decrease in the quality and quantity of production. Weed biocontrol, especially by using plant pathogenic fungi, has received attention but is still lacking in application. The purpose of this study was to determine the potential of Fusarium sp. and Chaetomium sp. as biological control agents against five broad-leaf weeds (Asystasia gangetica L., Ageratum conyzoides L., Synendrella nodiflora (L.) Gaertn., Wedelia trilobata (L.) U.S. Hitchc. and Amaranthus spinosus L.). The variables observed were the incubation period, disease incidence, disease intensity, as well as weed fresh and dry weight. The results of this study showed that the two pathogenic fungi, Fusarium sp. and Chaetomium sp., can cause a more intensive disease in A. conizoides than A. spinosus. A. gangetica, S. nodiflora and W. trilobata; however, the fungi have not been able to inhibit the growth and kill the weeds. Therefore, improvement need to be done by modifying the media to increase the ability of fungi to control weeds.
