“…20 Additionally, high-temperature water washing (100 °C) demonstrated more effective removal of phenolic compounds than cold water, potentially because of enhanced phenolic solubility. 21 Activated carbon (XAD-4 resins) used in liquid hot water pretreated hydrolysates successfully eliminated 90% of phenolics and partially removed FF, leading to a 30% enhancement in sugarcane bagasse (SCB) digestibility. 22 Furthermore, biological detoxification involving laccase and/or peroxidase enzymes demonstrated the removal of 70% of phenolic concentration, resulting in a 16% increase in glucan enzymatic hydrolysis.…”

“…Dyes containing azo and triarylmethane chromophore groups (Methyl Orange, Nolan Gruen E-B 400%, Basic Blue 1, Malachite Green and Malachite Oxalate Green) had the highest decolorization rates from 0.79 to 0.5 after 24 h ( Table 1 ). The high decolorization efficiency of these dyes in the presence of LPMO can be correlated with the reducing potential of these dye molecules [ 28 , 29 ]. The ability of such compounds to accept or donate electrons is influenced by electron-donating or electron-withdrawing substituents attached to the chromophore molecules.…”

“…In previous investigations, it was indicated that the deprotonation of the pyrrolidines ring promotes stronger binding to the active site of the copper atom. As a general trend, molecules with higher denticity and higher ionic strength could be bound to the active site copper atom of LPMO more easily and increase the degradation efficiency [ 28 ].…”

The textile industry is one of the largest water-polluting industries in the world. Due to an increased application of chromophores and a more frequent presence in wastewaters, the need for an ecologically favorable dye degradation process emerged. To predict the decolorization rate of textile dyes with Lytic polysaccharide monooxygenase (LPMO), we developed, validated, and utilized the molecular descriptor structural causality model (SCM) based on the decision tree algorithm (DTM). Combining mathematical models and theories with decolorization experiments, we have elucidated the most important molecular properties of the dyes and confirm the accuracy of SCM model results. Besides the potential utilization of the developed model in the treatment of textile dye-containing wastewater, the model is a good base for the prediction of the molecular properties of the molecule. This is important for selecting chromophores as the reagents in determining LPMO activities. Dyes with azo- or triarylmethane groups are good candidates for colorimetric LPMO assays and the determination of LPMO activity. An adequate methodology for the LPMO activity determination is an important step in the characterization of LPMO properties. Therefore, the SCM/DTM model validated with the 59 dyes molecules is a powerful tool in the selection of adequate chromophores as reagents in the LPMO activity determination and it could reduce experimentation in the screening experiments.

“…In addition, phenolic compounds (e.g., lignin) were reported as inhibitors to the fermentation and AD of LCB. Chavan et al [188] developed the extraction of the lignin by the presence of gallic acid to promote hydrolysis of the cellulose and hemicellulose to produce glucose to be fermented. The remaining residues are suitable for pyrolysis to avert fermentation and AD costs.…”

Globally, fossil fuel dependence has created several environmental challenges and climate change. Hence, creating other alternative renewable and ecologically friendly bio-energy sources is necessary. Lignocellulosic biomass has gained significant attention recently as a renewable material for biofuel production. The large amounts of plantain and banana plant parts wasted after harvesting, as well as the peels generated daily by the fruit market and industries, demonstrate the potential of bioenergy resources. This review briefly assesses plantain and banana plant biomass (PBB) generated in the developing, developed, and underdeveloped countries, the consumable parts, and feasible products yield. It emphasized the advantages and disadvantages of the commonly adopted treatment technologies of composting, incineration, and landfilling. Further, the utilization of PBB as catalysts in biodiesel synthesis was briefly highlighted. To optimize recovery of biofuel, different integration routes of pyrolysis, anaerobic digestion, fermentation, hydrothermal carbonization, hydrothermal liquefaction, and hydrothermal gasification for the valorization of the PBB were proposed. The complex compounds present in the PBB (hemicellulose, cellulose, and lignin) can be converted into valuable bio-products such as methane gas and bio-ethanol for bioenergy, and nutrients to promote bioactive ingredients. The investigation of the viability and innovation potential of the integrated routes' technology is necessary to improve the circular bio-economy and the recovery of biofuels from biomass waste, particularly PBB.
