John, I don't know that CC can digest whole kernel corn...and doubt they could any better than a human will, unless well chewed. Filamentous algae cells are small, and need a pH lower than what a CC's stomach acid is to break the protein barrier at the cellular level on FA to extract nutrient....additionally, the pharyngeal teeth will not grind the algae enough to help weaken the cellular structure....Like poorly chewed whole kernel corn, FA will pass through the entire digestive tract virtually unchanged on exit...
