Algae growth and mitotic index ration of the two algae cultures exposed to ALAN. No significant differences in algae density in Cladocopium and Durusdinium cell cultures (A,B) after one-month exposure to ALAN resulting from blue, yellow or white LEDs; irradiance level 0.15 μmol quanta m–2 s–1 (4–5 lux). Data are expressed as mean ± SEM (n = 3). One way-Anova (p > 0.05) between control and different light treatments (A,B). In contrast there are significant differences in the Mitotic Index (MI) (C,D), Data are expressed as mean ± SEM (n = 3), ANOVA was followed by post hoc Tukey’s test, asterisks indicate significantly different mean values (*p < 0.05; **p < 0.01, ***p < 0.001, and ****p < 0.0001).
