Characterization of a Microalgal UV Mutant for CO2 Biofixation and Biomass Production

Table 1

Maximum biomass concentrations (Xmax), maximum specific growth rates (μmax), and maximum biomass productivities for S. obliquus parental strain (PS) and mutant (SDEC-1M) under air and 15% (v/v) CO2 for 7 days. Each data indicates the mean ± SD, which was measured from three independent cultures. Each value in parentheses indicates the time (d) in which the maximum value of the parameter occurs. Data in the same parameter followed by different letters are significantly different by Duncan’s test (p < 0.05).
