Influence of Bio-AgNP on Growth and Biochemical Composition of Spirulina platensis
Abstract
Spirulina platensis is an important source of pharmaceutically active metabolites. It is important to enhance and enrich the biomass of S. platensis cultures. Silver nanoparticles (AgNPs) have been used in many areas of biotechnology and biologically-synthetized silver nanoparticles (bio-AgNPs) have more beneficial effects on biosystems than chemically-synthetized AgNPs. In our study, Syzygium aromaticum-derived bio-AgNPs were added to S. platensis batch culture at 0–25 mg/L concentrations and the responses were evaluated. The highest optical densities and dry weight were detected at 5 mg/L bio-AgNP concentration, whereas 15 mg/L bio-AgNP triggered the highest fresh weight. Total phenolic, flavonoid and antioxidant capacities were also detected at their highest values between 1 and 15 mg/L bio-AgNP concentrations. The results revealed that bio-AgNP concentrations can be optimized and used as elicitors in order to enhance the growth and improved the biochemical composition.
