This sounds pretty disgusting
If you have 4 types of algae, i'm sure that would be sufficient variety for some types of grasshoppers. Some grasshopper eat just one type of food and some eat anything. Then you get proteins from your grind up grasshoppers and fat from your algae. Some color and some spices and some creative shape, texture from your printer and voila a tasty space snack.http://www.3ders.org/articles/20130912-soon-you-can-3d-print-health-food-at-home-with-algaerium-bioprinter.html
...But since you bring up the subject of space food, have space agencies ever considered something like Soylent?
