Abstract | The effects of silicate and glucose on growth and eicosapentaenoic acid (EPA) production by the diatom Nitzschia laevis were studied. By alternately altering the concentrations of silicate (2.7-64 mg l-1) and glucose (1-40 g l-1) in the medium, the highest cell dry weight (ca. 5.5 g l-1) was obtained at 20 g l-1 glucose and 32 mg l-1 silicate, while the highest specific growth rate (ca. 0.65 day-1) was obtained at a relatively low glucose concentration (5 g l-1) and high silicate concentrations (32-64 mg l-1). At glucose levels of 5 and 20 g l-1, EPA content was higher with lower silicate concentrations (2.7 and 16 mg l-1 silicate, respectively), while at a silicate level of 16 mg l-1, higher glucose concentrations (20-40 g l-1) facilitated EPA formation. The highest EPA yield (131 mg l-1 was obtained at 20 g l-1 glucose and 32 mg l-1 silicate, while the highest EPA productivity (15.1 mg l-1 day-1) was obtained at 20 g l-1 glucose and 64 mg l-1 silicate. |
