Application of the Spectrophotometric Method for Determination of the Cell Numbers of Microalgae in the Genus Tetraselmis (Chlorophyta): Calibration Curves and Equations for Calculation.

The spectrophotometric method is used to count the number of microalgal cells. Regression equations were obtained for four species of the genus Tetraselmis (Chlorophyta), that are widely used in biotechnology. The correlation coefficients between cell number and absorbance were 0.856, 0.941, 0.787, and 0.916 for Tetraselmis viridis, T. striata, T. maculata, and Tetraselmis sp. respectively, which demonstrates the precision of this method for cell counting.
