Auxin-like activity of Scenedesmus obliquus biomass when applied in the mung bean root development bioassay for the eight microalgal treatments (T1–T8) at the two concentration tested (0.5 and 2 g/L) using indole-3-acetic acid (IBA) at 0.3, 0.7 and 1 mg/L as the auxin standard. Results are shown as mean ± SE (n = 3). Different letters indicate significant differences (p < 0.05) within each treatment.
