Multilevel heuristic LED regime for stimulating lipid and bioproducts biosynthesis in Haematococcus pluvialis under mixotrophic conditions.

•Novel multilevel LED regimes with C5 organic carbons were developed for mixotrophic microalgae.•Adaptation phase played an important role on the algal biomass and bioproducts accumulation under multilevel LED regimes.•Saturated fatty acids contributed to 35.1% of total triglyceride fatty acids production at white-red regime.•The white-blue regime increased the astaxanthin content by 51.6%.
