Abstract
Since nanoparticle synthesis via chemical and physical methods is expensive and includes hazardous
chemicals, biosynthesis has emerged as an environmentally friendly, clean and viable alternative. The
present study reports the synthesis of selenium nanoparticles (SeNPs) using Citricoccus sp.. For the
production of SeNPs, the influence of some parameters (time, pH, temperature and stirring rate) was
studied. Optimum synthesis conditions were found as pH 8, 24 h reaction time, 37 °C and 150 rpm.
Synthesized particles were spherical and were 104.46 ± 50.82 nm with a zeta potential of –20.43 ± 0.41
mV. Afterward, the effects of the nanoparticles on oxidative stress biomarkers, hydrogen peroxide (H2O2),
malondialdehyde (MDA), chlorophyll (a+b) and growth rate, subsequent to UV-C irradiation on Chlorella
vulgaris were investigated. In culture contains nanoparticle and UV-C exposed, the amount of H2O2 and
MDA decreased on the 1st, 3rd and 7th days following UV exposure compared to UV-applied group, while
optical density and cell density increased, the amount of chlorophyll (a+b) changes were statistically
similar. Consequently, it has been shown that the synthesized SeNPs alleviated the adverse effects of UV
stress in microalgae.
