Spirulina platensis
is a blue-algae/cyanobacterium which has been used as a rich
food-supplement in east Africa (and Mexico) by the local population
for hundreds of years. In recent years its quick growth
characteristics and ease of cultivation has led to a “rediscovery”
by several development aid organisations. However their focus was
mostly of medium to large scale local production, which was shown to
be effective.
In contrast we would
like to investigate if a small scale cultivation in discarded PET
bottles with household level means can produce a sufficient amount
for personal consumption.
