Response surface methodology was used to optimize extraction parameters for Morchella esculenta SO-01 exopolysaccharide (EPS) produced during submerged culture. The optimum conditions for EPS extraction were predicted to be, concentration at 84.07 degrees C, precipitation for 22.19 h and pH 8.44, and EPS production was estimated at 5.45 g/L. The actual(More)
The extraction conditions of intracellular polysaccharide (IPS) from Pleurotus sp. mycelium in submerged culture were investigated. Four parameters affecting the IPS extraction, ultrasonic treatment time, extraction temperature, extraction time and ethanol concentration, were determined by single factor tests and then optimized by orthogonal experiments.(More)
Response surface methodology (RSM) was used to optimize the extraction parameters for Pholiota adiposa SX-02 intracellular polysaccharide (IPS) produced during submerged culture. The optimum conditions of IPS extraction were predicted to be, ultrasonic power at 564.93 W, precipitation time 30.34 h and pH 8.28, and IPS yield was estimated at 19.75%. The(More)
Extra- (EPS) and intracellular polysaccharides (IPS) from Pholiota nameko SW-01 were extracted, and in vitro and in vivo antioxidant effects were processed. Briefly, the in vitro antioxidant results indicated that the inhibition effects of IPS at a dose of 500 mg/L on superoxide anions, hydroxyl radicals, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals(More)
