Fig. 3-4. Growth curve of N. silvestris in 

 suspension cultures. A) Cell growth monitored as cell 

 count or as dry weight. The physiological stages of 

 growth: lag (L) , exponential (E) and stationary (S) are 

 indicated in each panel. B) Soluble protein content was 

 determined in samples harvested daily and was related to 

 the dry wt . and cell number. Comparable protein values 

 obtained with EE cells (average of ten determinations) 

 are indicated with stippled bars, the widths of which 

 indicate the range of variation.
