“…The monomers and oligomers released may affect the water balance, and modify the protein-starch interactions which may result in decreased resistance of dough to gas flow, and hence the improved dough-rise. Furthermore, use of xylanases decrease the dough firmness, create more uniform and finer crumbs, and increase the volume by forming the water soluble arabinoxylan from insoluble arabinoxylan, and even play role in reducing the staling rate of the bread [27]. Similar results were obtained by Elegbede and Lateef [11] who have shown that crude xylanase from Aspergillus flavus SD4A and Aspergillus fumigatus L2 strain enhanced the dough volume to 2.2 and 1.87-fold, respectively.…”

“…5I). Xylanases have been used either standalone or in combination with other enzymes for improving the characteristics of bakery products [16,27]. The dough rise due to A. terreus S9 xylanase application is attributed to the cleavage of arabinoxylans resulting in release of water, consequently softening the dough.…”

“…Application potential of xylanases standalone, or in combination with other enzymes like pectinases and cellulases, has been investigated for liquefaction of fruits and vegetables, clarification of fruit juices, reducing juice viscosity, and for enhancing juice yield [11,18,27]. In bread making, the xylanase application may enhance dough rheological characteristics (extensibility, flexibility, stability), bread quality (crumb structure, texture, porosity), and shelf life [8,37].…”

Discovery of new/novel enzymes with process-apt features has been a continuous practice. A wide range pH-stable and thermostable xylanase was reported hitherto from a newly isolated fungal strain Aspergillus terreus S9, from mushroom compost. This is the first ever report where-in a pH-stable and thermostable xylanase is being reported from a strain of A. terreus. Solid state fermentation was executed on agro-industrial residues for xylanase production. Maximum xylanase production was supported by wheat bran (40 U/ml), however, substantial xylanase yield was observed on other residues like corn cob powder (38.4 U/ml), cotton cake (38 U/ml), malt (37.6 U/ml) and almond hulls (35.2 U/ml). Almond hulls are being reported for the first time as the substrate for xylanase production. Plackett-Burman design was used to earmark the most effective process variables (wheat bran, medium pH, and incubation time), and the same were optimized by design of experiments (DoE) based on response surface methodology to achieve a yield enhancement of 1.82-fold. A. terreus S9 xylanase exhibited an excellent and brisk clarification of mosambi and orange juices. DoE based optimization of process parameters (enzyme dose, treatment time and incubation temperature) resulted in 1.23-fold and 1.28-fold enhanced orange and mosambi juice clarification, respectively. Furthermore, admirable dough raising capacity and pulp brightening ability of A. terreus S9 xylanase shows its promising potential for bread making, and eco-friendly biobleaching processes, respectively. The xylanase must be in-depth investigated to decipher the molecular mechanisms of diverse applications.

“…9 Xylans have been used in various industrial applications such as the food industry, feed industry, pharmaceutical industry, and packaging materials. 10 Therefore, there is a need to find an alternative to these commercially unavailable substrates with similar chemical composition and structure. Xylans have been extracted and characterized from different sources such as from rye straw, 12 wheat bran, 13 cotton stalk, 14 corn, 15 and sugarcane.…”

Over the past two decades, birchwood and beechwood xylans have been used as a popular substrate for the characterization of xylanases. Recently, major companies have discontinued their commercial production. Therefore, there is a need to find an alternative to these substrates. Xylan extraction from Acacia sawdust resulted in 23.5% (w/w) yield. The extracted xylan is composed of xylose and glucuronic acid residues in a molar ratio of 6:1 with a molecular mass of ∼70 kDa. The specific optical rotation analysis of extracted xylan displayed that it is composed of the d-form of xylose and glucuronic acid monomeric sugars. The nuclear magnetic resonance analysis of extracted xylan revealed that the xylan backbone is substituted with 4-O-methyl glucuronic acid at the O2 position. Fourier transform infrared analysis confirmed the absence of lignin contamination in the extracted xylan. Xylanase from Clostridium thermocellum displayed the enzyme activity of 1761 U/mg against extracted xylan, and the corresponding activity against beechwood xylan was 1556 U/mg, which confirmed that the extracted xylan could be used as an alternative substrate for the characterization of xylanases.
