Figure 3.

CC-5325 had more chlorophyll and carotenoids per cell than CC-1690, mainly due to the larger cell volume of CC-5325. Chlorophyll and carotenoids measured by absorbance change using a spectrophotometer. (a,b) Chlorophyll content per cell and per cell volume, respectively. (c,d) Carotenoid content per cell and per cell volume, respectively. (e) Chlorophyll a/b ratio. (f) Chlorophyll/carotenoid ratio. Mean ± SE, N = 3 biological replicates. Statistical analyses were performed using a two-tailed t-test assuming unequal variance by comparing with CC-1690: *, p < 0.05; ns, not significant.
