“…Other spectroscopic techniques are Fourier transform infrared spectroscopy (FTIR) [ 117 ] and near infrared spectroscopy (NIR) [ 118 ]. FTIR and NIR are based on the infrared absorption with which the molecular vibration of lignin is detected, so the purity of lignin or lignocellulosic materials can be calculated as well as quantifying approximate values of the S/G ratio of purified samples of lignin [ 15 , 115 ].…”

“…The study of the composition of the cell wall of tree and herbaceous species is due to the potential for use in the paper industry [ 11 , 12 ] and biofuels [ 13 , 14 ]. Currently, there are standardized analytical techniques to characterize the composition of the cell wall, from methods to quantify the percentages of each cell component, such as the TAPPI standards [ 15 ], to specialized methods as chromatography, nuclear magnetic resonance, and spectroscopy to analyze and characterize the structural monomers of each lignocellulosic component [ 16 ].…”

Lignin is one of the most studied and analyzed materials due to its importance in cell structure and in lignocellulosic biomass. Because lignin exhibits autofluorescence, methods have been developed that allow it to be analyzed and characterized directly in plant tissue and in samples of lignocellulose fibers. Compared to destructive and costly analytical techniques, fluorescence microscopy presents suitable alternatives for the analysis of lignin autofluorescence. Therefore, this review article analyzes the different methods that exist and that have focused specifically on the study of lignin because with the revised methods, lignin is characterized efficiently and in a short time. The existing qualitative methods are Epifluorescence and Confocal Laser Scanning Microscopy; however, other semi-qualitative methods have been developed that allow fluorescence measurements and to quantify the differences in the structural composition of lignin. The methods are fluorescence lifetime spectroscopy, two-photon microscopy, Föster resonance energy transfer, fluorescence recovery after photobleaching, total internal reflection fluorescence, and stimulated emission depletion. With these methods, it is possible to analyze the transport and polymerization of lignin monomers, distribution of lignin of the syringyl or guaiacyl type in the tissues of various plant species, and changes in the degradation of wood by pulping and biopulping treatments as well as identify the purity of cellulose nanofibers though lignocellulosic biomass.

“…Peak 1728.7 cm −1 shows C-O stretching indicating the presence of acetyl and ester linkage in lignin and hemicellulose. Meanwhile, peaks 1243.4, 1160.3 and 1034.8 cm −1 also show C-O stretching but indicate stretching of hemicellulose and lignin [41,42]. Based on these peaks, it shows that raw bagasse consists of cellulose, hemicellulose and lignin that form lignocellulosic components.…”

A Novel Natural Active Coagulant Agent Extracted from the Sugarcane Bagasse for Wastewater Treatment

et al. 2022

The performance of extracted coagulant from the sugarcane bagasse was tested using synthetic wastewater for turbidity removal. Sugarcane bagasse was selected because it is available in abundance as a waste. This study was carried out to analyze the effect of the extraction process in optimizing the active coagulant agent of bagasse as a natural coagulant for optimum turbidity removal. Bagasse was characterized in terms of physical, chemical and morphological properties. The results showed bagasse has very high polysaccharide content which can act as an active coagulant agent together with hemicellulose and lignin. The extraction process for degradation of lignin and hemicellulose was run based on two different solvents (NaOH and H2SO4) with varying concentrations from 2% to 10% at different extraction temperatures varied from 60 °C to 180 °C for various extraction times (0.5 h to 3 h). The optimum polysaccharide content extracted from bagasse was 697.5 mg/mL by using 2% NaOH at 120 °C for 2 h extraction. The coagulation process using extracted bagasse showed the removal of suspended solids up to 95.9% under optimum conditions. The concentration of polysaccharides as the active coagulant agent plays a vital role where high polysaccharides content removes most turbidity at a lower dosage. Bagasse has the potential to be an alternative coagulating agent due to its efficiency, and eco-friendly properties for the treatment of wastewater.

“…The truncation of the WBT stage and subsequent addition of the fibrous state later in ontogeny (Figure 9D, E) can be also interpreted as a case of peramorphosis with an early onset of additional terminal stages. In the Opuntioideae, WBTs are present exclusively in the rays, while their polymorphic wood development frequently involves multiple switches between fibrous and parenchymatous wood (Arruda, 2010; Maceda et al, 2020).…”

Evolutionary developmental biology (evo‐devo) explores the link between developmental patterning and phenotypic change through evolutionary time. In this review, we highlight the scientific advancements in understanding xylem evolution afforded by the evo‐devo approach, opportunities for further engagement, and future research directions for the field. We review evidence that (1) heterochrony—the change in rate and timing of developmental events, (2) homeosis—the ontogenetic replacement of features, (3) heterometry—the change in quantity of a feature, (4) exaptation—the co‐opting and repurposing of an ancestral feature, (5) the interplay between developmental and capacity constraints, and (6) novelty—the emergence of a novel feature, have all contributed to generating the diversity of woods. We present opportunities for future research engagement, which combine wood ontogeny within the context of robust phylogenetic hypotheses, and molecular biology.
