SCRS barcodes of Chlamydomonas reinhardtii CC124 and Nannochloropsis oceanica IMET1 under nitrogen depletion conditions. Population average (a) and heterogeneity index (b) of protein content, starch content, TAG content and lipid unsaturation degree (I 1658/I 1441) based on the 13 marker Raman bands in averaged SCRS of three biological replicates of culture at each time point are shown, which revealed graphically the distinct dynamic features of these key traits between the starch biosynthetic process of C. reinhardtii and the TAG-accumulating process of N. oceanica under nitrogen depletion conditions. The color of barcode indicates the relative intensity of Raman bands and was assigned based on the normalized intensity value within each Raman band
