Adsorption of Acid Yellow 36 and direct blue 86 dyes to Delonix regia biochar-sulphur by Ahmed Eleryan, Uyiosa Osagie Aigbe, Kingsley Eghonghon Ukhurebor, Mohamed A. Hassaan, Safaa Ragab, Otolorin Adelaja Osibote, Ismail Hossain, Ahmed El Nemr

“…The Langmuir model (LGM) and pseudo-second-order-model (PSOM) best describe the biosorption of both dye molecules to the biosorbent owing to the equal and homogeneous spread of the dye molecules over the biosorbent porous surface and a chemisorption process which involved the valency force through the exchange of electrons between the dye molecules and the prepared biosorbent. The determined biosorption capacities for both dyes (AY36 and DB86) were found to be 270.27 mg/g and 36.23 mg/g, respectively. …”

Impact of Enzymatic Degradation Treatment on Physicochemical Properties, Antioxidant Capacity, and Prebiotic Activity of Lilium Polysaccharides by Kaitao Peng, Yujie Zhang, Qi Zhang, Yunpu Wang, Yuhuan Liu, Xian Cui

“…In order to overcome the bioavailability limitation of <i>Lilium</i> polysaccharide (LPS) caused by its high molecular weight and complex structure, two low-molecular-weight degraded polysaccharides, namely G-LPS(8) and G-LPS(16), were prepared through enzymatic degradation. The molecular weight of LPS was significantly reduced by enzymolysis, leading to increased exposure of internal functional groups and altering the molar ratio of its constituent monosaccharides. …”
