Fv/Fm, S. costatum
Fv/Fm = 0.53
Fm = 438.4



Above is an image of the 1 liter culture of S. costatum on a metal rack with a couple of fluorescent lights in the background. The image was taken a few moments prior to determining the health of the cells (Fv/Fm). As one can see, the culture of happily photosynthesizing cells is not very dense. However, either tomorrow or the day after, the same beaker will be brown/green due to the exponential growth of the culture.
