“…Xylans from agro-industrial residues are classified depending on the type of side groups and degree of substitutions. For example, arabinoxylans are generally present in sugarcane and cereals, such as wheat, rye, barley, oats, rice, corn, and sorghum, and in grasses there is a higher presence of L-arabinose [40].…”

“…The group of enzymes involved in this method is called hemicellulases, which can degrade hemicellulose into smaller polymers and sugars. Xylanases (endo-1,4-β-xylanases, EC 3.2.1.8) are one of the most representative enzymes within this group, classified as endo enzymes that catalyze the hydrolysis of the β-1,4 linked chains of xylose to produce small XOs [40,73,76,77]. Xylanases are grouped as glycoside hydrolases (GH) in the families of glycosidases 10 (GH10) and 11 (GH11) [72].…”

“…Arabinofuranosidases (EC 3.2.1.55) can act on polysaccharides containing arabinose, catalyzing the hydrolysis of the glycosidic bond of the nonreducing terminal, generating arabinoglucoxylans, arabinoxylan, and arabinans [81,82]. Feruloyl esterases hydrolyze the ester bond between the arabinose and ferulic acid substituents in xylose, while acetyl esterases hydrolyze acetyl substituents in xylose [40]. The β-xylosidases (EC 3.2.1.37) have the ability to hydrolyze xylobiose at the nonreducing end, as well as soluble XOs, releasing xylose.…”

In recent years, concerns about a good-quality diet have increased. Food supplements such as prebiotics have great nutritional and health benefits. Within the diverse range of prebiotics, xylooligosaccharides (XOs) show high potential, presenting exceptional properties for the prevention of systemic disorders. XOs can be found in different natural sources; however, their production is limited. Lignocellulosic biomasses present a high potential as a source of raw material for the production of XOs, making the agro-industrial by-products the perfect candidates for production on an industrial scale. However, these biomasses require the application of physicochemical pretreatments to obtain XOs. Different pretreatment methodologies are discussed in terms of increasing the production of XOs and limiting the coproduction of toxic compounds. The advance in new technologies for XOs production could decrease their real cost (USD 25–50/kg) on an industrial scale and would increase the volume of market transactions in the prebiotic sector (USD 4.5 billion). In this sense, new patents and innovations are being strategically developed to expand the use of XOs as daily prebiotics.

Background Sustainable strategies for enteric methane (CH4) mitigation of dairy cows have been extensively explored to improve production performance and alleviate environmental pressure. The present study aimed to investigate the effects of dietary xylooligosaccharides (XOS) and exogenous enzyme (EXE) supplementation on milk production, nutrient digestibility, enteric CH4 emissions, energy utilization efficiency of lactating Jersey dairy cows. Forty-eight lactating cows were randomly assigned to one of 4 treatments: (1) control diet (CON), (2) CON with 25 g/d XOS (XOS), (3) CON with 15 g/d EXE (EXE), and (4) CON with 25 g/d XOS and 15 g/d EXE (XOS + EXE). The 60-d experimental period consisted of a 14-d adaptation period and a 46-d sampling period. The enteric CO2 and CH4 emissions and O2 consumption were measured using two GreenFeed units, which were further used to determine the energy utilization efficiency of cows. Results Compared with CON, cows fed XOS, EXE or XOS + EXE significantly (P < 0.05) increased milk yield, true protein and fat concentration, and energy-corrected milk yield (ECM)/DM intake, which could be reflected by the significant improvement (P < 0.05) of dietary NDF and ADF digestibility. The results showed that dietary supplementation of XOS, EXE or XOS + EXE significantly (P < 0.05) reduced CH4 emission, CH4/milk yield, and CH4/ECM. Furthermore, cows fed XOS demonstrated highest (P < 0.05) metabolizable energy intake, milk energy output but lowest (P < 0.05) of CH4 energy output and CH4 energy output as a proportion of gross energy intake compared with the remaining treatments. Conclusions Dietary supplementary of XOS, EXE or combination of XOS and EXE contributed to the improvement of lactation performance, nutrient digestibility, and energy utilization efficiency, as well as reduction of enteric CH4 emissions of lactating Jersey cows. This promising mitigation method may need further research to validate its long-term effect and mode of action for dairy cows.

“…Xylose is the main component of hemicellulose and the second most abundant sugar in nature after glucose ( Zhao et al, 2020 ; Kawaguchi et al, 2006 ). Xylose is widely used in food ( Sasanam et al, 2021 ; Corim Marim and Gabardo, 2021 ), medicine ( Zhou and Murphy, 2010 ; Cheudjeu, 2020 ; Chen et al, 2020 ), and chemical industry ( Zhang et al, 2022a ; Wang et al, 2022 ) as food additive ( Sasanam et al, 2021 ; Corim Marim and Gabardo, 2021 ), drug excipients ( Cheudjeu, 2020 ), and feedstock ( Zhou and Murphy, 2010 ; Chen et al, 2020 ; Zhang et al, 2022a ; Wang et al, 2022 ). In addition, xylose can also be used as carbon and energy for microbial metabolism and growth.…”
