【Abstract】 Aim: To investigate the relationship between optical density (OD) and the biomass of microalgae. Methods: 15 microalgal species were used under laboratory conditions to study the relationship between the cell density and its related OD. Meanwhile, the optical absorption coefficient, namely the slope of the linear graph which showed the relationship between cell density and OD, was utilized to estimate the phytoplankton biomass. Results: Regression analysis results showed the linear function: lg( m )=-0.451 1 ln( x )+4.242 2, in which c is the carbon content and x is the optical absorption coefficient of microalgae. Conclusion: This is a useful and rapid OD method to measure the biomass of microalgae . [更多还原
