What does spirulina look like?

Arthrospira platensis, aka spirulina, is a helical colony or tricome.  Below are some of the features we use to describe the tricome.

Pitch:  Similar to wavelength.  It is the distance between two peaks in the tricome. The pitch can be between 7-50.  

Colony Length:  The length of the entire colony.  This length is usually 20-300nM.  Harvestable spirulina is usually 60-200nM in length.

Diameter:  This is the width of the individual cells of the tricome.  The diameter is usually 4-7nM.
