“…This reappearance of the peak could be attributed to fungal autolysis, resulting in the release of intracellular enzymes into the medium [19]. Similar trends in laccase production have been observed in fungal pretreatment of corn stover with other fungal strains, albeit with lower yields compared to the present study [10,13,40]. During pretreatment, xylanase and mannanase were also produced, which were responsible for the degradation of the hemicellulose content of corn stover.…”

Biological pretreatment of lignocellulosic residues has the potential to serve as a sustainable, less energy-intensive alternative to harsh chemical treatments for enhancing cellulose accessibility, despite the requirement of a lengthy incubation period. The study characterized the simultaneous delignification of corn stover by the white-rot fungus Pyrenophora phaeocomes S-1, as well as the co-production of a ligno-hemicellulolytic enzyme cocktail consisting of laccase, xylanase, and mannanase. The maximum yields of all three components of the cocktail were achieved after just 4 days of incubation under solid-state conditions. Following a 40-day fermentation period, we achieved a cellulose recovery of 44.25 ± 1.72%, attributed to the activities of 133.88 U/gds of laccase, 14.93 U/gds of xylanase, and 1.34 U/gds of mannanase co-produced by the fungus in the medium. Subsequently, through the extraction of biologically treated biomass with 0.5N NaOH after 40 days, the cellulose recovery increased to 66.4 ± 1.39%. Enzymatic hydrolysis of the same, employing only 5 FPU/gds of in-house produced cellulases, resulted in the liberation of 397.84 mg/gds of total reducing sugars after 144h. The findings of this study encourage further optimization of biological pretreatment of lignocellulosic residues and enzymatic hydrolysis to enhance the yields of total reducing sugars for their valorization.

“…At different time points (10,20,30,40, and 60 days) of incubation, the flasks were withdrawn in duplicate, and the contents were mixed with distilled water. The crude enzyme extract (CEE) was then extracted from the mixture as described in section 2.3.…”
