Abstract
The aim of this work was to examine the potential of the thermophilic green microalga Micractinium sp. to accumulate triacylglycerols (TAGs) and to develop a light strategy to increase TAG productivity in this alga. To this end, dense cultures of Micractinium sp. were grown at 37â¯Â°C under nitrogen (N) starvation and exposed to a light intensity of 1000â¯Âµmolâ¯photonsâ¯mâ2â¯sâ1 of different light regimes. The highest per-biomass TAG-content and maximal volumetric productivities of TAG were displayed by the cultures grown under flashing light of 5â¯Hz with 50% duty cycle. Based on the results, a sufficiently high-starting culture density should be combined with a high irradiance delivered by an appropriate light regime to enhance the production of biomass enriched TAGs.
