Ethanol induced astaxanthin accumulation and transcriptional expression of carotenogenic genes in Haematococcus pluvialis

•Ethanol had positive effect on astaxanthin accumulation of H. pluvialiseven under low light intensity (25μmolm−2s−1)•Maximum increment of astaxanthinproductivity was11.26mgL−1d−1•Ethanol greatly enhanced transcription of ipi-1 and ipi-2•An ethanol fed-batch induction method was developed Haematococ...
