Investigation into the effects of CbXyn10C and Xyn11A on xylooligosaccharide profiles produced from sugarcane bagasse and rice straw and their impact on probiotic growth

Abstract This comparative study investigated the effects of CbXyn10C and Xyn11A on xylooligosaccharide profiles produced from sugarcane bagasse (SCB) and rice straw (RS) and their impact on probiotic growth. Generally, CbXyn10C produced more xylose and a higher total phenolic content than Xyn11A. Interestingly, XOS obtained from SCB with CbXyn10C contained significantly more gallic acid than that produced by Xn11A. All selected probiotics thrived in RS-derived XOS, regardless of the enzyme used. However, probiotics grew differently on SCB-derived XOS depending on the enzyme used. All probiotics thrived in Xyn11A-derived XOS from SCB. Only Lactobacillus plantarum thrived on CbXyn10C-derived XOS, while the other two were inhibited. Gallic acid in CbXyn10C-derived XOS from SCB has been linked to probiotic retardation, and gallic acid-enriched broth has been found to inhibit Bifidobacterium longum and Bacillus subtilis, but not L. plantarum. Consequently, the selection of enzymes and plant biomass is crucial for XOS properties and prebiotic effects.
