“…Between the probiotics, LcS had a significant higher growth rate compared to Bfd. Indeed, Lactobacillus strains had a better ability to grow on XOS derived from agriculture wastes, while the growth of Bifidobacterium strains was not much different than the control (Jagtap et al, 2017). Hence, XOS from SW has the potential to be combined with LcS, in the preparation of synbiotics food.…”

Wastes from agricultural industry are often disposed. Nevertheless, these wastes contain nutraceuticals and functional compounds. Xylooligosaccharide (XOS) was extracted from two sugarcane wastes (SW); rind (SR) and pith (SP), and the prebiotic properties of both XOS were examined. SR and SP had different mixture of XOS and were resistant towards a-amylase and gastric juice digestion in vitro. Although the growth of Lactobacillus casei Shirota (LcS) and Bifidobacterium animalis subsp. Lactis ATCCÒ 700541 TM increased significantly in both XOS after 48 h of incubation, XOS from SR showed better enrichment of probiotics growth. Both XOS were found to be more fermentable by LcS and acetic acid was the predominant end product of the fermentation. Since XOS composition was different between SR and SP and such difference can affect their prebiotic properties, it is important to choose the appropriate parts of SW to extract XOS with high fermentable properties and obtain the best synbiotics combination.

“…They have come to the forefront of investigations due to their variety of health benefiting effects such as acting as prebiotics, lowering cholesterol level, improving the biological availability of calcium, etc. They also exhibit wide range of biologic activities including antioxidant, anti‐inflammatory, immunomodulatory, and anti‐cancer . XOs are mainly produced by chemical methods, enzymatic degradation, or combined chemical‐enzymatic method from the xylan‐rich hemicelluloses .…”

Characterization of a novel xylanase from Aspergillus flavus with the unique properties in production of xylooligosaccharides

et al. 2019

A novel xylanase from the filamentous fungus Aspergillus flavus was purified and characterized as the β‐1, 4‐endoxylanase (designed as AfXynB) with a molecular mass (32.2 kDa), which is different from all of the previously reported xylanases from the same strain. AfXynB was optimally active at pH 7.5 and 55 °C, respectively. It was stable up to 50 °C within range of pH 4.0–9.5, and displayed an excellent tolerance to various cations, reagents, and proteases. AfXynB showed specific activity toward beechwood xylan but no detected activity toward CMC and pNP‐β‐D‐xylopyranoside. The xylanase is a typical endo‐xylanase; it could hydrolyze beechwood xylan to only yield xylobiose (X2) and xylopentaose (X5). Actually, this may be the first report for the endo‐xylanases that displayed such a unique hydrolytic property. These findings in the present study have great implications for its future applications of the novel xylanase.

“…Therefore, the enzymatic route is preferred by the food industry because of the minimization of these undesirable side reactions and by-products [232]. Nevertheless, although examples of direct enzymatic hydrolysis without previous chemical or thermal pretreatment of the biomass can be referred [239,240], most researchers report pretreatments. Although acid and alkaline hydrolysis [241][242][243], even with additional microwave-assisted processing [244], have been employed as pretreatments, the combination of an initial autohydrolysis step followed by the enzymatic hydrolysis of the obtained xylan can be mentioned as a more promising option [106,245,246].…”

A Bibliometric Study of Scientific Publications regarding Hemicellulose Valorization during the 2000–2016 Period: Identification of Alternatives and Hot Topics

A bibliometric analysis of the Scopus database was carried out to identify the research trends related to hemicellulose valorization from 2000 to 2016. The results from the analysis revealed an increasing number of annual publications, a high degree of transdisciplinary collaboration and prolific contributions by European researchers on this topic. The importance of a holistic approach to consider the simultaneous valorization of the three main components of lignocellulosic biomass (cellulose, hemicellulose and lignin) must be highlighted. Optimal pretreatment processes are critical for the correct fractionation of the biomass and the subsequent valorization. On the one hand, biological conversion of sugars derived from hemicellulose can be employed for the production of biofuel (ethanol) or chemicals such as 2,3-butadiene, xylitol and lactic acid. On the other hand, the chemical transformation of these sugars produces furfural, 5-hydroxyfurfural and levulinic acid, which must be considered very important starting blocks for the synthesis of organic derivatives.
