The total XOS yield with optimum ozone dose of 3% (OAAH-3) was found to be 8.9% (w/w biomass) at 110 degrees C in comparison to 7.96% at 170 degrees C by autohydrolysis (AH) alone. Although, there was no significant difference in oligomeric composition (DP 2-6), significant decrease in degradation products namely furfural (2.78-fold), HMF (3.15-fold), acrylamide (nil) and acetic acid (1.06-fold), was observed with OAAH-3 as a pretreatment option. There was 1-fold higher xylan to XOS conversion and OAAH-hydrolysate had higher DPPH radical scavenging activity than AH. PCA plots indicated clear enhancement in XOS production and lower generation of inhibitors with decrease in treatment temperature. Results of the study therefore suggest OAAH can be an effective pretreatment option that can further be integrated with downstream processing for concentration and purification of XOS.10aAdvanced oxidation10aAgro-industry waste10ahydrothermal treatment10aOzonolysis10aXylooligosaccharide1 aSonkar, Rutuja, Murlidhar1 aGade, Pravin, Savata1 aBokade, Vijay1 aMudliar, Sandeep, N.1 aBhatt, Praveena  uhttps://library.ncl.res.in/content/ozone-assisted-autohydrolysis-wheat-bran-enhances-xylooligosaccharide-production-low02273nas a2200229   4500008004100000022001400041245014000055210006900195260000800264300001200272490000800284520146600292653002301758653001601781653001401797653001501811653002501826100001701851700002001868700002401888856013101912       2023                        eng d  a0263-876200aDual activity cavitation reactors for increased efficacy in degradation of refractory pollutants-A case study on cephalexin degradation0 aDual activity cavitation reactors for increased efficacy in degr  cAPR  a310-3220 v1923 a<p>
	The present work discloses a new form of cavitation processes using reactors of dual activity for increased efficiency. A proof of concept is established for the degradation of a refractory pollutant-cephalexin using both conventional and dual function cavitation reactors for the first time using acoustic and hydrodynamic cavitation (HC). A vortex diode as a cavitating device was employed for HC using aluminium as a non-catalytic and copper as dual function device for providing additional catalytic effect. The process in-tensification using hydrogen peroxide (H2O2) coupled with the dual function devices was highly effective. A negligible degradation with only HC and 81% for HC coupled with H2O2 in 60 min for Al-vortex diode compared to 100% degradation in only 5 min for the copper device clearly demonstrates the order of magnitude enhancements establishing dual function due to catalytic activity. Also, pH modification (pH 11) yields enhancement over 300% for Cu-vortex diode. The use of dual function reactors drastically reduces H2O2 do-sage. The overall enhancements in the per pass degradation and cavitation yields were huge, similar to 3000% and 1450% respectively, highlighting the potential of the dual function ca-vitation reactors in real-life applications, not just for increased efficiencies but also for significantly reduced costs.(c) 2023 Institution of Chemical Engineers.
