فرایند یک مرحله ای تولید پلی3هیدروکسی بوتیرات کو هیدروکسی والرات) از پساب های بدست آمده از کارخانه های روغن کشی زیتون توسط هالوفراکس مدیترانه ای

عنوان انگلیسی: A one-stage cultivation process for the production of poly-3 (hydroxybutyrate-cohydroxyvalerate) from olive mill wastewater by Haloferax mediterranei چکیده انگلیسی: Abstract: Olive mill wastewater (OMW), a highly polluting waste from the olive oil industry, was utilized as sole carbon source for the production of polyhydroxyalkanoate (PHA) by extremely halophilic Haloferax Mediterranei (H. mediterranei) in a one stage cultivation step. H. mediterranei showed remarkable cell growth and tolerated the inhibitory effect of polyphenols present in medium containing 25% of OMW. H. mediterranei cultivation conditions were optimized in medium containing 15% OMW by investigating several parameters that affect the production of PHA. The highest polymer yield (0.2 g/L) and PHA content (43% PHA/cell dry mass) were achieved at 37 C, 170 rpm and 22% salt concentration. Analysis of
