FIG. 5.
Growth characteristics of strain NZ9000(pFL010) (•) and strain NZ9000(pNZ8148) (○) under non-pH-controlled aerobic conditions. (A) Cell growth. (B) Glucose consumption. (C) pHex. (D) Ammonium formation. Cultivations were performed in a 2.5-liter jar fermentor containing 2 liters of CM. The aeration rate was 2 liters/min, and the agitation speed was controlled at 600 rpm. Results are expressed as the means of duplicate measurements at the same time points in three independent experiments. The standard deviations were lower than 10% of the values.
