     to maximize the biomass and lipid production for applications in food or biofuel feedstock, nine stress conditions were tested considering n and/or p limitations, light intensity & quality, for haematococcus pluvialis sccap k-0084 cultivation. photosynthetically active radiation (par), warm white light emitting diode (wwled), and white light emitting diode (wled) at illumination of 240 μmol photons m−2 sec−1were the best stress-regulatory factors. par without p & low n conditions yielded high biomass with 33% lipids containing increased c16:0 and c18:0 saturated fatty acids, and reduced unsaturated fatty acids (ufas) (oleic, linoleic, and α/γ-linolenic). wwled and wled without p conditions also yielded high biomass, but 25% lipids with increased amounts of ufas. red light emitting diode (rled) without p & low n conditions yielded 46% lipids with lowest biomass. par and wwled & wled illuminated conditions were found suitable respectively for biodiesel feedstock lipids and ufa-rich lipids for multiple applications.
