Characterization by photoacoustic spectroscopy of the photosynthetic Scenedesmus armatus system affected by fuel oil contamination

The effects of aqueous fuel oil extract (AFOE) on the photosynthetic energy storage in cultures of the green microalgae Scenedesmus armatus were investigated using photoacoustic spectroscopy. A 38 per cent decrease in photosynthetic energy storage was observed for 90 per cent AFOE. The plot of relat...

Description
Summary:The effects of aqueous fuel oil extract (AFOE) on the photosynthetic energy storage in cultures of the green microalgae Scenedesmus armatus were investigated using photoacoustic spectroscopy. A 38 per cent decrease in photosynthetic energy storage was observed for 90 per cent AFOE. The plot of relative energy storage versus the light intensity was determined and from this a mathematical formula was adapted to derive the photosynthetic system parameters. After 24 h growth of the culture in the presence of AFOE the maximal photosynthetic yield for Scenedesmus armatus was reduced by 41 per cent. There are 30 references.
