At Maker Faire Bay Area 2011, Aaron Wolf Baum shows a tank of spirulina he grows from home. A bacterial superfood, spirulina can be grown in alkaline conditions that prevent contamination from harmful bacteria, and then can be filtered and eaten as an ingredient in such foods as guacamole, soups, or smoothies.

    So cool — thanks for sharing! One thing to note, though, is that it’s an algae, not a bacteria.

    From Wikipedia: “Spirulina is a human and animal food or nutritional supplement made primarily from two species of cyanobacteria: Arthrospira platensis and Arthrospira maxima.” Although you did have us googling around to make sure! =]

    You are right. While it used to be classified as an algae, it is indeed a (few types of) bacteria. They just call it blue-green algae still to throw folks for a loop ;)
    And it looks like this tiny organism is making waves with its pharmacological applications (against some cancers and viruses, including HIV).
    Again, thanks for sharing. I lovelovelove this site and the creativity it cultivates!
