“…A study obtained a higher lignin component removal rate and reduced sugar yield in the acid assistance treatment (2% HCl, two hours, 123 • C) of bean straw. Still, the biogas production did not increase significantly comparing the sole thermal pretreatment (1 h, 121 • C) [117].…”

“…Li et al [110] found that thermal pretreatment increased Pennisetum's maximum biogas production rate and total methane yield, with an improvement of around 7% and 8%, respectively. Montoya-Rosales et al [117] reported that thermal pretreating bean straw at 121 • C for one hour showed effectiveness in hemicellulose degradation (60%), cellulose solubilization (51%), and improving biogas yield (145.4 mL•g −1 COD). Bolado-Rodríguez preheated Wheat straw and Sugarcane bagasse at 121 • C for 60 min, resulting in a 29% and 11% increase in biogas production, respectively.…”

Low-temperature pretreatment (LTPT, Temp. < 100 °C or 140 °C) has the advantages of low input, simplicity, and energy saving, which makes engineering easy to use for improving biogas production. However, compared with high-temperature pretreatment (>150 °C) that can destroy recalcitrant polymerized matter in biomass, the action mechanism of heat treatment of biomass is unclear. Improving LTPT on biogas yield is often influenced by feedstock type, treatment temperature, exposure time, and fermentation conditions. Such as, even when belonging to the same algal biomass, the response to LTPT varies between species. Therefore, forming a unified method for LTPT to be applied in practice is difficult. This review focuses on the LTPT used in different biomass materials to improve anaerobic digestion performance, including food waste, sludge, animal manure, algae, straw, etc. It also discusses the challenge and cost issues faced during LTPT application according to the energy balance and proposes some proposals for economically promoting the implementation of LTPT.

“…Even filamentous fungi that are psychrophilic or psychrotolerant have this trait. Pathogenic fungus Sclerotinia borealis, which thrives in extremely cold environments and cannot grow over 20 °C, produces pectinases, which are most active at 40 °C [63]. Another example of a thermotolerant fungus is Mucor flavus, which produced pectinases that are most active at 45 °C [64].…”

Three possible novel Didymella species, isolated from Mango and Guava juices in Assiut, Egypt, were identified based on morphology and sequencing of the internal transcribed spacers region (ITS). The three strains could ferment five lignocellulosic residues, namely bean straw, corn cobs, rice husk, wheat bran, and wheat straw in solid-state fermentation (SSF) and produce cocktail enzymes (endoglucanase, exoglucanase, laccase, pectinase, and xylanase). Didymella sp. AUMC 15636 and AUMC 15637 produced the most endoglucanase, exoglucanase and xylanase activity (20 and 23, 10 and 17, 18 and 18 U/gds, respectively) on bean straw, and laccase (0.7 and 2.6 U/gds) on corn cobs and wheat bran, in addition to pectinase (37 and 26 U/gds) on rice husk and corn cobs, respectively. Didymella sp. AUMC 15640 released the maximum endoglucanase, exoglucanase, laccase, pectinase, and xylanase enzymes on the bean straw residues (24, 24, 10, 31 and 27 U/gds), respectively. Didymella sp. AUMC 15636 yielded 0.9 g crude pectinase per liter fermentation medium in submerged fermentation (SmF). At pH 6.0, a peak in pectinase activity (80 U/gds) was detected, which rose to 100 U/gds at 45 ºC. Presence of Mn 2+ ions activated the pectinase by 30% over the control. Zn 2+ and EDTA had no effect on pectinase activity, while sodium dodecyl sulfate and other ions lowered pectinase activity by 10 to 30%, while K + and Ca 2+ having the highest impact. The target of this study, which is advocated here by utilizing such strains, is to

“…Nevertheless, T. latifolia had a lower lignin content than both switchgrass (31.2%) and eucalyptus (29.4%) [41], and several agricultural wastes, such as sorghum straw (30.4%) [39], cotton stalk (30.0%), and walnut shell (37.5%) [1]. Additionally, the total carbohydrates (62.4 ± 0.7%) in the T. latifolia biomass were higher than those of lignocellulosic materials such as banana pseudostems (51.5%) [42], bean straw (55.0%) [43], switchgrass (56.8%) [44], olive tree (57.8%) [45], and sugar cane (60.7%) [46], which are promoted as feedstock to produce biofuels. These total carbohydrate percentages demonstrate that T. latifolia biomass could be utilized to generate cellulosic ethanol.…”

Lignocellulosic biomass has garnered attention as an abundant and sustainable alternative energy source that can facilitate reliable and environmentally friendly energy generation. Energy security improves, and environmental impacts diminish when bioethanol, a biofuel produced via lignocellulose-based processes, is utilized. The lignocellulosic biomass of Thysanolaena latifolia has considerable potential as a bioethanol feedstock due to its high carbohydrate content (62.4 ± 0.7%). In this study, feedstock derived from T. latifolia was pretreated with various concentrations of H3PO4 to determine the ideal conditions for enzymatic hydrolysis to convert the feedstock to fermentable sugar. The findings revealed that hydrolysis efficiency and glucose recovery yields were substantially improved compared to those of the untreated sample. Pretreated samples were enzymatically digested to produce a liquid hydrolysate. This hydrolysate was fermented without detoxification using Saccharomyces cerevisiae TISTR 5339 to produce ethanol. The results indicated that T. latifolia biomass hydrolysate is a promising long-term carbon source for ethanol production from cellulosic biomass. Furthermore, the morphological and crystallographic characteristics of the treated T. latifolia biomass were influenced by H3PO4 concentration, as indicated by the SEM images, X-ray diffractogram patterns, and crystallinity index values. Therefore, utilizing T. latifolia feedstock to produce bioethanol can enhance bioenergy sustainability.
