Organic Spirulina Cultivation

Aim: To test different organic fertilizers in a spirulina growing application and examine the differences in yield and nutritional content of the final product. Developing a low cost method by which people can grow spirulina with home-made organic fertilizers.

Why it’s important: To test different organic fertilizers in a spirulina growing application and examine the differences in yield and nutritional content of the final product. Developing a low cost method by which people can grow spirulina with home-made organic fertilizers. Spirulina is a very nutritionally dense food that aids in healing and detoxification of the body. Consuming spirulina is a way that growing children in many developing countries are able to get the nutrients that their diets are often lacking. Teaching people how to grow their own spirulina will ensure there is an abundant and low cost supply. Spirulina is an organism that grows in both fresh and salt water. It is a photosynthetic type of bacteria called cyanobacteria, which is often referred to as blue-green algae. First projects run in Cusco, Peru, where extreme poverty and nutritional deficiencies are prevalent. Growing spirulina at reasonable scale is a functional carbon sink if human waste is recycled into biogas and soil treatments, and take sustenance agricultural pressure off adjacent rainforests, such as Urubamba in the case of Cusco Province.

There also appears to be a native Peruvian spirulina-type cyanobacteria which would could try to grow: https://en.m.wikipedia.org/wiki/Nostoc_commune

How it works: Spirulina is an organism that grows in both fresh and salt water. It is a photosynthetic type of bacteria called cyanobacteria, which is often referred to as blue-green algae.

Brief Outline of Process: Different shallow pools of water are inoculated with the same species of spirulina and different fertilizer combinations in a dry desert climate. After the growth period yields are examined and the results will be documented and an optimum formula for growing spirulina with home-made fertilisers will be found.

Equipment Needed: food grade plastic sheeting as a liner, spade, fertilizers and sea mineral, spirulina starter culture from Xarxa Cataluña, fine mesh for harvest, dehydrator, and peristaltic pumps

Time Needed: 30 hours documentation, 40 hours construction/harvest/maintenance time

Experiments: Different fertilizer combinations and NPK and trace minerals values.

Production of Foamed Glass: For large scale operations, food grade plastic sheeting is not ecological, so it will only be used for small scale initial experimentation. Long term we will investigate the production of foamed glass, a lightweight photopermeable block used in oyster farming, as an ecological low impact solution to large scale spirulina production, and this will also help us create subtropical marine habitats for atmospheric carbon capture, biodiversity refugia and planktonic collapsed fishery recuperation in collaboration with large scale international fishing industry and subtropical marine biologist fisheries specialist Rebecca Korda (phD. Marine Biology, University of Newcastle), as a complement to tropical accelerated coral reef regeneration methods with Nicholas Ovenden MSc., both of which are scalable with macro fishing industry partnerships and Elemental Electrical´s industrial “Pay to Purify” clients.
