- Abstract
As the shift toward environmentally renewable resources occurs algae cultivation for lipids, co-products and biomass, as a source of antioxidants, food, livestock feed, cosmetics and renewable fuel feedstock is of continuing growing interest. In this work we describe the profile and content of carotenoids and lipids of a promising microalgae identified as a Chlorococcum sp. Experiments were performed in environmental photobioreactors (ePBRs) and incubators under constant, low and high intensity irradiance. Metabolite, lipid, and carotenoid profiles determination was done during the transition from green vegetative cells to the highly pigmented carotenogenic cells. The objective of this work was to gather a better understanding of carbon allocation and lipid synthesis/remodeling events of the Chlorococcum sp. strain under increased photooxidative stress and other environmental stressors. This biochemical basis of the relationship between stress inducing conditions, carotenoid synthesis, high lipid content and fatty acid composition is beneficial for further increasing the productivity and economic development of this Chlorococcum strain.
