@MiyukiXu These 6 species were chosen because there is interest in using these species for biofuel development, or as model organisms
Practically speaking, these particular 6 microalgae would probably not be found in the same natural water environment. the amount would depend on the source
@JGaladePablo Hey Julia, Thanks for putting all of this together! We show 3 colors here actually, 2 fluorescent and 1 brightfield, However this technique isn't limited to only 2 fluorescent colors. It has the same limitations as normal fluorescent techniques, so ~10 would be possible.
