spectral conversion of light using rhodamine 6g for enhancing the nitrate removal rate of green microalgae chlorella sp.

Nitrate removal by chlorella sp. under different illumination conditions was evaluated in this study. white and modified white light by r6g at intensity of 300 µmol m-2s-1 were considered as light sources. the results corroborate the fact that spectral shifting by using r6g solution caused about 2-fold increase of biomass production. additionally, it performed 100% efficiency in n removal in only two days which was the shortest processing time compared to other cultures. the advantage of r6g employment as a light shifter revealed its effectiveness over white light. nitrate removal by chlorella sp. under different illumination conditions was evaluated in this study. white and modified white light by r6g at intensity of 300 µmol m-2s-1 were considered as light sources. the results corroborate the fact that spectral shifting by using r6g solution caused about 2-fold increase of biomass production. additionally, it performed 100% efficiency in n removal in only two days which was the shortest processing time compared to other cultures. the advantage of r6g employment as a light shifter revealed its effectiveness over white light.
