“…The use of biological agents like fungi as part of other pretreatment techniques is known as biological pretreatment. Commonly utilized as biological pretreatment agents include white-rot fungi, brown-rot fungi, and soft-rot fungi [21,22,41]. After pretreatment, cellulose, and hemicellulose are hydrolyzed to yield straightforward fermentable sugars.…”

Phytoremediation is using live plants to remove toxins and contaminants from land, water, or the air. Hydrocarbons, radionucleotides, fertilizers, explosives, heavy metals, and other contaminants are all efficiently removed from wastewater by this approach. Aquatic plants can be classified as free-floating, emergent, or submerged. Studies have been done on the capacity of Pontederia crassipes Mart. to extract pollutants like dissolved solids, and heavy metals from wastewater. The pollution of chromium in Indian chromite mining sites has also been addressed it and following phytoremediation, the biomass may be utilized to produce vermicompost, biogas, and bioethanol. Surface mining is producing changes in land use, land cover, and climate in the RCF area of West Bengal, India. By using aquatic plants to phytoremediate pit lakes (PLs), fresh water can be produced and chances for sustainable livelihoods can be created. The population in former mining regions has grown significantly, leading to the relinquishment of agriculture and the development of illegal mining and coal theft. This study aims to examine the literature on aquatic plant phytoremediation of water, emphasizing the necessity of phytoremediation of PL water in RCF and the potential applications of Pontederia crassipes Mart. biomass for the generation of biogas, bioethanol, and vermicompost.

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.
