Figure 9.

Cellular carbon accumulation rates before and during the first 24 h after nitrogen deprivation. Accumulation during nitrogen-replete growth was derived from growth rates and total cellular carbon contents; carbon accumulation after deprivation is due to starch and lipid production. Filled symbols represent autotrophic conditions (HS media), while empty ones represent mixotrophic and heterotrophic conditions (TAP media). Squares indicate Y values for total carbon accumulation (starch plus total FAME), while diamonds and circles represent starch and total FAME, respectively. Within each series, increasing light levels correspond to symbols from left to right. Error bars depict ±sd (n = 3). The dashed line corresponds to a slope of 1, and the solid line is the least-squares best fit to the autotrophic total carbon accumulation results.
