Abstract The current work aims to evaluate the plant growth regulators (PGRs) content in some microalgae and cyanobacteria species cultivated in an inexpensive media. Two cyanobacterial (Anabaena oryzae and Nostoc muscurum) and a chlorophyte species (Chlorella vulgaris) from six algal species, were selected according to the concentration of auxins and cytokinin‘s analyzed by HPLC. They cultivated on treated sewage wastewater (TSW) combined with BG medium at different concentrations (100, 75, and 50% TSW). The Biological activities include antimicrobial and antioxidant (using DPPH radical methods) of absolute methanol extracts were evaluated. In addition, application experiments of IAA and BA presence in algal extract was applied on tomato canola plantlets and soybean callus. The genetic stability among the produced in vitro plantlets of both plant species was evaluated by ISSR and RAPD markers. The obtained results revealed that the use of sewage wastewater as media for cultivation of the investigated algae is safe, suitable, cheap and not expensive methods when compared with the ordinary used media with low genetic divergence |
