“…The significantly higher value of pristane in biofilm under HL and D (ANOVA, p<0.05) could be thus linked to MPB organisms' damage, and/or to a higher grazing activity of micromeiofaunal organisms caused by the stressing irradiance conditions (darkness or too much light). The neophytadiene was measured in some microalgae (López-Rosales et al, 2019) like marine diatoms (Marella et al, 2021). This is an isoprenoid belonging to the terpene and it can arise from the phytol which is itself a Chla degradation product (Rontani and Volkman, 2003).…”
