Abstract: 

The elements of Zn and Mn are essential for ‘growth of microalgae but their build up promote biological problems for microalgae structure in aquatic environments. In this research, exclusive effects of different concentrations of Zn (450, 900 and 1350 mg/l) and Mn (75,150 and 225 mg/I), and their combined effects (450+75, 900+150, and 1350+225 from Zn+Mrr’ in mg/l)" on "some physiological parameters of population dynamic, growth, chlorophyll and carotenoid contains in green microalgae Scenedesmus quadricauda were investigated under laboratory conditions of temperature of 22±2 °C, photoperiod of 12 hours light: 12 hours dark, and light intensity of 80 umol photons/m2/s. The experiment was carried out as completely randomized design with three replications for a 22 days period. Results showed that the peak of population density obtained at 900 mg/L of Zn, 150 mg/l of Mn and their combination 900+150 mg/I of Zn+Mn. The maximum growth rates were 0.060, 0.058 and 0.056 /day for Zn, Mn and their combination, respectively. The minimum doubling time of population attained 11.6 days at 900~mg/1 of Zn. The maximum chlorophyll a and total carotenoid were 1.8 and 93.2 mg/L, respectively, at 900 mg/L of Zn which had significant differences with other treatments. The findings of this study showed that increasing of Zn up to 900 mg/L and Mn up to 150 mg/I that resulted to improving of population, growth, chlorophyll a and total carotenoid in the S. quadricauda. As conclusion, this study illustrated that changing of Zn and Mn concentrations had significant effects on cell density, chlorophyll a and total carotenoid. The effects of Zn were higher than Mn and its increasing to concentration of 900 mg/I caused improving of physiological characters of S. quadricauda.
