Dependence of pigment content on number of days of diatom culture. Phaeodactylum tricornutum was cultivated at 15 °C, under white fluorescent light (100 μmol photons m−2 s−1) in a 16/8 h day/night photoperiod. Samples were collected after 1 h of darkness. Pigment content was determined by HPLC and expressed as a percentage value. The data are means of three replicates; a sample marked with an asterisk is mean of seven replicates. Statistical data are given in Table A.1 in Supplementary Material
