“…Xylooligosaccharides are short oligomers composed of xylose moieties and are commonly derived from corn cob, bamboo shoots, wheat straw, sugarcane bagasse, and hardwood xylan. Among these, corn cob contains the highest amount of xylan (35–38%), and hence, it can be exploited as a cheap and renewable source of XOS ( 31 ). Based on the sugar units and linkages present, the exact composition and the quantity of the produced XOS vary from one plant source to another.…”

The gut microbiota in the human body is an important component that plays a pivotal role in the ability of the host to prevent diseases and recover from these diseases. If the human microbiome changes for any reason, it affects the overall functioning of the host. Healthy and vigorous gut microbiota require dietary fiber supplementation. Recently, oligosaccharides have been found to play a significant role in the modulation of microbiota. Several such oligosaccharides, i.e., xylooligosaccharides (XOS), mannooligosaccharides (MOS), and arabino-xylooligosaccharides (AXOS), are derived from hemicellulosic macromolecules such as xylan, mannan, and arabino-xylan, respectively. These oligosaccharides serve as substrates for the probiotic production of health-promoting substances (short-chain fatty acids, branched chain amino acids etc.), which confer a variety of health benefits, including the prevention of some dreaded diseases. Among hemicellulose-derived oligosaccharides (HDOs), XOS have been largely explored, whereas, studies on MOS and AXOS are currently underway. HDOs, upon ingestion, help reduce morbidities by lowering populations of harmful or pathogenic bacteria. The ATP-binding cassette (ABC) transporters are mainly utilized for the uptake of oligosaccharides in probiotics. Butyrate generated by the selective fermentation of oligosaccharides, along with other short-chain fatty acids, reduces gut inflammation. Overall, oligosaccharides derived from hemicelluloses show a similar potential as conventional prebiotics and can be supplemented as functional foods. This review summarizes the role of HDOs in the alleviation of autoimmune diseases (inflammatory bowel disease, Crohn's disease), diabetes, urinary tract infection, cardiovascular diseases, and antimicrobial resistance (AMR) through the modulation of the gut microbiota. The mechanism of oligosaccharide utilization and disease mitigation is also explained.

“…Transesterification reaction of coffee spent, Buriti, and Acai oils by immobilized lipase in Sepabead-C18 in the presence of ethanol was performed [23]. XOs have the advantage to be fermented by specific bacteria such as Bifidobacterium and Lactobacillus that act as probiotics [77][78][79]. SSF of rice husk was carried out by A. nidulans XynC A773 to produce xylanase and XOs.…”

Aspergillus nidulans is a filamentous fungus that is a potential resource for industrial enzymes. It is a versatile fungal cell factory that can synthesize various industrial enzymes such as cellulases, β-glucosidases, hemicellulases, laccases, lipases, proteases, β-galactosidases, tannases, keratinase, cutinases, and aryl alcohol oxidase. A. nidulans has shown the potential to utilize low-cost substrates such as wheat bran, rice straw, sugarcane bagasse, rice bran, coir pith, black gram residue, and chicken feathers to produce enzymes cost-effectively. A. nidulans has also been known as a model organism for the production of heterologous enzymes. Several studies reported genetically engineered strains of A. nidulans for the production of different enzymes. Native as well as heterologous enzymes of A. nidulans have been employed for various industrial processes.

“…Recent researches showed that XOS are non-digestible saccharides with prebiotic action (Bindels, Delzenne, Cani, & Walter, 2015;Cunningham et al, 2021;Swanson et al, 2020). Generally, sugarcane bagasse and corncob are used as feedstocks to prepare XOS (Amorim et al, 2019;Poletto et al, 2020). In addition, other lignocellulosic biomass, such as bamboo, brewery residues, also can produce XOS (Monteiro et al, 2021;.…”

“…Based on the reported research, acid, alkaline, and hydrothermal pretreatment are the main strategies for the fractionation of hemicelluloses and the production of XOS (Amorim et al, 2019;Poletto et al, 2020). Among these methodologies, hydrothermal pretreatment was gaining popularity relative and was considered an economically feasible method to produce signi cant amounts of XOS with a low degree of polymerization (DP) and inhibit the depolymerization of XOS (Gullón et al, 2018;Rico et al, 2018).…”

Chinese hickory shell, a by-product of the food industry, is still not utilized and urgent to develop sustainable technologies for its valorization. This research focuses on the systematical evaluation of degraded products and xylooligosaccharide production with high yield from the shell via hydrothermal process. The results indicated that the pretreatment condition strongly affected the chemical structures and compositions of the liquid fraction. The maximum yield of XOS (55.3 wt%) with limitation of by-products formation was achieved at 160 oC for 2 h. High temperature (220 oC) and short time (0.5 h) contributed to hydrolysis of xylooligosaccharide with high DP to yield 37.5 wt% xylooligosaccharide with DP from 2 to 6. xylooligosaccharide obtained mainly consisted of xylan with branches according to the HSQC NMR analysis. Overall, the production of XOS with a high yield from food waste will facilitate the valorization of food waste in the biorefinery industry.
