New Biotechnological Production of EPA by Pythium irregulare Using Alternative Sustainable Media Obtained from Food Industry By-Products and Waste

نویسندگان

چکیده

Long-chain polyunsaturated fatty acids (LC-PUFAs) have multiple beneficial effects on human health, in particular docosahexaenoic acid (DHA, 22:6, n-3) and eicosapentaenoic (EPA, 20:5, n-3). A variety of microorganisms has been used for the commercial production non-animal-source LC-PUFAs. The oomycetes Pythium family are promising EPA producers, this work, optimization irregulare growth using food industry by-products wastes as cheap sources nutrients was carried out. Sugar cane molasses (SCM), spent brewery yeast (SBY), cheese whey (CW), expired orange juice (EFJ) were tested. combination SBY a source nitrogen EFJ organic carbon resulted best outcome among other sustainable media ingredients. new medium conducted through response surface methodology factors. results show significant positive impact these factors biomass productivity (p < 0.005), with an optimized yield 14.22 g L?1, lipid 2.23 concentration 155 mg L?1.
