A simple strategy for the separation and purification of water-soluble polysaccharides from the fresh Spirulina platensis
Wang, Feng; Ma, Yong; Liu, Yanhua; Cui, Zhenggang; Ying, Xiaoyan; Zhang, Fuming; Linhardt, Robert J. (2017-02-11)A novel and industrially applicable strategy for separating and purifying the water-soluble polysaccharides from the fresh Spirulina platensis is introduced in this study. After hot water extraction, using chitosan ... -
Amphiphilic bromelain-synthesized oligo-phenylalanine grafted with methoxypolyethylene glycol possessing stabilizing thermo-responsive emulsion properties
Wang, Feng; Zhu, Jinwen; Yan, Tingting; Pei, Xiaomei; Zhang, Fuming; Linhardt, Robert J. (2019-03-07)A thermo-responsive amphiphile was developed from oligo-phenylalanine [oligo(Phe)]. The hydrophobic moiety of the amphiphile, oligo(Phe) was synthesized via reverse hydrolysis catalyzed by bromelain in dimethyl sulfoxide ... -
Amphiphilic mPEG-modified oligo-phenylalanine nanoparticles chemoenzymatically synthesized via papain
Wang, Feng; Li, Youhua; Yu, Lu; Zhu, Jinwen; Zhang, Fuming; Linhardt, Robert J. (American Chemical Society (ACS), 2020-11-24)Amphiphilic mPEG-modified peptide nanoparticles were developed from oligo-phenylalanine (OPhe) nanoparticles (NPs) synthesized via papain. Tyndall effects indicate that OPhe NPs are amphiphobic. Addition of protein ... -
Improved octyl glucoside synthesis using immobilized β-glucosidase on PA-M with reduced glucose surplus inhibition
Wang, Feng; Ma, Yong; Liu, Yan Hua; Zhang, Xuan; Zhang, Fuming; Linhardt, Robert J. (2017-09-03)A β-glucosidase extracted from bitter almond (Prunus dulcis var. amara) was immobilized on polyamine microspheres (PA-M) for catalytic octyl glucoside (OG) synthesis from glucose and octanol through reversed hydrolysis. ... -
Preparation of salidroside with n-butyl β-D-glucoside as the glycone donor via a two-step enzymatic synthesis catalyzed by an immobilized β-glucosidase from bitter almond
Wang, Feng; Huang, Dengfa; Ma, Yong; Zhang, Fuming; Linhardt, Robert J. (2019-07-04)β-Glucosidase from bitter almonds was immobilized on epoxy group-functionalized beads for catalyzing salidroside synthesis in a two-step process with n-butyl-β-D-glucoside (BG) as the glucosyl donor. The formation of ...
