Figure 3

Time-dependent changes in cell growth and the concentrations of GA and DHA in G. frateurii NBRC103465 cultures. Cells were cultivated in a 5-L jar fermenter containing 2.5 L of glycerol medium at 30°C, 500 rpm, and 0.5 vvm. The pH of the cultures was controlled using a synthetic solution modeled after the raw glycerol, which contains 30% (w/v) methanol (solid lines, open symbols); the control contained no methanol (broken lines, closed symbols). Cell growth was evaluated by measurement of the OD at 600 nm. Squares: cell growth; circles: GA concentration; triangles: DHA concentration.
