materials and methods the expression of hyaluronidase antigenic fragments was optimized using iptg concentration, time of induction, temperature, culture, and absorbance of 0.6-0.8-1 at 600 nm. afterwards, the expressed proteins were purified and the enzymatic activity was assessed by turbid metric method. results data indicated that maximum protein is produced in od = 0.8, 0.5 mm isopropyl β-d...

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...
