Study the effect of kerosene on some physiological activities in Oscillatoria splendida

The effect of different concentration Kerosene had been examined upon Oscillatoria splendida, optical density depended as measure for growth well chlorophyll a concentration, Phycocyanin pigment and protein an indicator effects, in addition to morphological changes. the control sample was (0.34), while it (0.23) at 0.25% kerosene It is noted slowing with high treatment, 0.5% peak (0.08), resisted influence transactions 1% 2%, but low values. under (0.32) mg /ml, (0.165) /ml kerosene, Chlorophyll concentrations have fallen minimum 2%. Protein (0.215, 0.86) mg/ml respectively, In spite doubling values did not reduced Completely. Some changes were observed such yellowing cells colors slight increase length cells. As absorption spectrum infrared by FTIR show that splendida consume many bundle (2870) cm-1 (2950) cm-1, also disappearance 2300) cm -1, 1500 appearance new (800) Attributed introduction compound found sample.
