“…3A). These results are comparable to our previous study where we reported a higher CMCase activity (~ 195 U ml −1 ) of T. reesei M184 at 96 h of cultivation in SSF experiment [18]. Here, we reported the higher CMCase activities of both fungi at 144 h of cultivation, and this might be due to variations in culture conditions or SmF experiment.…”

“…There was an increasing trend of reducing sugar release with saccharification time and reached the maximum on the 8th day and then decreased. This increased trend of sugars profile suggests the increased hydrolytic activity of fungal isolates with time and is inconsistent with many past studies [18,52,53]. Here, the reducing sugars (437.05 ± 7.8 mg g −1 : Fig.…”

“…After incubation, the primary fungi cultures were sub-cultured on PDA and Sabouraud dextrose agar (SDA; Merck®, Darmstadt, Germany) plates for 3-4 times to remove the cross-contamination and to screen the pure fungi species.

“…The enzyme assays were performed at the 4th, 6th, 8th, and 10th days of the fermentation time course. Previously, the fungal cellulolytic activities have been evaluated either on a single biomass type [16,18,35] or on different biomass types [30,34]. Figure 2 A-D show the cellulolytic activities of CMCase, FPase, β-glucosidase, and xylanase of the sample fungi on wheat straw, corn con, and rice husk measured on the 10th day of fermentation.…”

“…Filamentous fungal species such as Trichoderma reesei and Aspergillus niger have demonstrated the higher ability of lignocellulose hydrolysis in several studies [16][17][18]. This might be attributed to the ability of these fungi to colonize the soil near plants and subsequent penetrations into plant tissues through the development of their hyphae and enzyme's release to hydrolyze the recalcitrant components [19].…”

Lignocellulosic biomass from agricultural waste seems promising feedstock for biofuel production; however, its degradation to fermentable sugars is challenging. Interestingly, fungi have shown substantial potential for the breakdown of lignocellulosic biomass and thus could be employed in lignocellulose-based biorefinery. Aiming at this, the current study was focused on screening the novel cellulolytic fungi from the surrounding environment. The preliminary molecular/morphological screening of 107 samples narrowed the experiment to 5 different fungi, designated: Aspergillus tubingensis AKF2, Aspergillus flavus AKF3, Pyricularia oryzae AKF4, Aspergillus nominus AKF5, and Aspergillus oryzae AKF6. The selected fungi were evaluated for their cellulolytic potential utilizing wheat straw, corn cob, and rice husk. The highest enzyme activity

Oilseed rape straw (OS), rice straw (RS), wheat straw (WS), and corn stover (CS) particles were used to reinforce bio‐polyols based polyurethane (PU) foams. The influence of crop straws (XS) fillers on the stability in water, degradability in soil, thermal stability, and elasticity of foams were investigated. The incorporation of OS and CS particles in the PU matrix increased the stability of reinforced foams in water, while the addition of WS and RS particles made foams lower stability in water. PU foams reinforced by XS particles displayed mass reductions up to 53.8% after burying in soil for 250 days. The reinforced foams were more stable under heating but the enhancement of thermal stability trended to disappear after water immersion or soil burying. The reinforced foams showed better elasticity that incorporations of OS and CS made PU foams higher height recovery percentage, while RS and WS made the recovery percentage decline firstly and then enhance during three times compressions. All these four XS particles are suitable to modify bio‐based PU foams, especially OS and CS particles appear to be more outstanding in preparing foams with higher stability in water, degradability in soil, thermal stability, and elasticity than RS and WS particles.

Lignocellulosic biomass, such as plant residues and agricultural waste, holds immense potential as a renewable resource for the production of biofuels, chemicals, and animal feed. However, the efficient degradation of lignocellulose into fermentable sugars remains a significant challenge. Recent research has highlighted the critical role of microbial diversity in lignocellulosic biomass degradation, offering new insights from a biotechnological perspective. The comprehension and utilization of microbial diversity are crucial for developing efficient biotechnological strategies for lignocellulosic biomass degradation. By uncovering the intricate relationships between microbial communities and their enzymatic machinery, researchers can optimize degradation processes, enhance biofuel production, and contribute to a more sustainable bio‐based economy. Microorganisms, including bacteria, fungi, and archaea, possess diverse enzymatic capabilities, allowing them to secrete a plethora of lignocellulolytic enzymes. Microbial organisms inhabiting extreme environments, such as the rumen, hot and cold springs, deep sea trenches, and acidic and alkaline pH environments, exhibit significant potential in generating enzymes, including hemicellulolytic and lignocellulolytic enzymes, which possess superior biochemical properties essential for industrial bioconversion applications. This review explores the ability of lignocellulosic enzymes from microbial sources to efficiently break down the lignocellulosic biomass and their potential applications in industrial biotechnology.
