- Abstract
Oleaginous microalga Nannochloropsis salina is known for its potential as a source of renewable bio-fuel due to its high oil yield. In addition N. salina is also a source for the value added polyunsaturated fatty acids (PUFAs) with relative high level of n-3 eicosapentaenoic acid (EPA). Lipid productivity and composition of oleaginous microalgae is variable and dependent on strain selection and environmental growth conditions. When environmental conditions lead to suboptimal temperatures aka: "cold stress" one of the response of the organism is to increase PUFAs metabolism leading to an increase in membrane fluidity decrease the negative impact that near freezing temperatures have on cellular components. In this study we report on the effect of suboptimal temperatures from 20oC to 5oC on the growth, physiological measurements and fatty acid profile of N. salina. In addition we investigated the fatty acid composition of different lipid species, lipid gene expression and how metabolic alterations and remodeling occur in various lipid pools with specific interest in TAGs.
