Table 1 Dry weight (pg cell− 1) and macromolecule contents (% cell dry weight), estimated by biochemical assays, of pure cultures of M. aeruginosa, A. oliquus and A. granulata grown at 15 and 25 °C. Values in parentheses are the standard deviations (n = 5). Different letters represent statistically different means (P < 0.05). Equal letters represent no significantly different means (P > 0.05)
