Isıl dirençli yeşil mikroalglerin antioksidan kapasitesi ve biyoaktif bileşikleri

Accumulation of reactive oxygen species (ROS) at high levels in cells as a result of normal cellular activities as well as exposure to oxidative stress is attributed to many chronic degenerative diseases and conditions in humans including cardiovascular diseases, cancer and aging-related conditions such as Alzheimer's disease. Although living organisms are equipped with enzymatic and non-enzymatic antioxidant defense systems to counteract the adverse effects of oxidative stress, yet they rely on exogenous sources of antioxidants for additional support. Despite, fruits and vegetables are the predominant sources, alternative sources of antioxidants such as microalgae are also being explored. In present study, novel thermo-tolerant green microalgal strains, Scenedesmus sp. ME02, Hindakia tetrachotoma ME03 and Micractinium sp. ME05, were evaluated for their antioxidant capacities, total phenolic, flavonoid and carotenoid contents in various solvent extracts.
