Towards the sustainable conversion of corn stover into bioenergy and bioproducts through biochemical route: Technical, economic and strategic perspectives

Metabolic Remodulation of Chassis and Corn Stover Bioprocessing to Unlock 3-Hydroxypropionic Acid Biosynthesis from Agrowaste-Derived Substrates

“…1 Among these agricultural wastes, corn stover is considered to be the most abundant. 2 To improve the economic viability of agricultural waste-based biorefineries, there has been a growing focus on the development of sustainable conversion technologies. 3 For example, chemoenzymatic conversion of corn stover into monomeric sugars, followed by microbial fermentation can produce ethanol.…”

“…Several technological achievements have been observed to overcome CCR by rational engineering 17 and toxicity through detoxifying the pretreated liquor or developing high-tolerant strains. 2 However, the direct use of a xylose-containing liquor is still a key challenge in achieving an efficient conversion process. In this context, utilizing glucose-containing cellulosic hydrolysate in this early research stage could avoid CCR effects and eliminate the need for detoxification or tolerance issues.…”

“…Despite promising results, simultaneous consumption of xylose and glucose from stover hydrolysate presents two technical challenges: carbon catabolite repression (CCR) and toxic effects of inhibitors (present in xylose-containing pretreated liquor) on enzymatic cellulose hydrolysis and microbial fermentation. Several technological achievements have been observed to overcome CCR by rational engineering and toxicity through detoxifying the pretreated liquor or developing high-tolerant strains . However, the direct use of a xylose-containing liquor is still a key challenge in achieving an efficient conversion process.…”

“…With the escalating global interest in green manufacturing practices, there has been a notable transition occurring from conventional fossil fuels to utilizing lignocellulosic wastes, especially agricultural residues, for producing biofuels and bioproducts . Among these agricultural wastes, corn stover is considered to be the most abundant . To improve the economic viability of agricultural waste-based biorefineries, there has been a growing focus on the development of sustainable conversion technologies .…”

The Potential Valorization of Corn Stalks by Alkaline Sequential Fractionation to Obtain Papermaking Fibers, Hemicelluloses, and Lignin—A Comprehensive Mass Balance Approach

“…The modern approach is to convert this abundant, renewable, and unavoidable resource into value-added products. Several reviews that highlight the benefits and opportunities of turning corn crop wastes into profitable goods are available in the literature [ 2 , 5 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. The potential uses of corn waste as raw materials in different industrial domains are briefly illustrated in Table S1 .…”
