Hello to you too, Hightaddict!
It is true that it is especially from a certain scale that the culture of spirulina becomes delicate: a messy parameter and it is a whole production that fails ...
For a host of trivial details, everything that is simple here becomes very complicated in Africa ...
Other tracks seem to me more interesting, like for example. the Moringa, shrub native to India and very rich in proteins, calcium and vitamins; moreover, it is easy to cultivate, very easy to master locally *.
To take full advantage of vitamins, it should be avoided as a cooked preparation; perhaps by drying and then reducing the powdered leaves to incorporate into traditional dishes?
* Provided you protect it from the cattle tooth!
Africa, spirulina against hunger and AIDS: it's fantastic

Hi Ahmed!
To have an optimal production, it must be a little complicated certainly. But artisanal production is easy and inexpensive.
I have been pampering for the experience for over a year now an 80 l container which this year produced just over 100 g of dried spirulina. My only tools for cultivation are the eyes, touch, smell, a thermometer and litmus paper: nothing too rocket science!
Moreover, if people are interested, a strain of spirulina very strong is available in the Midi-Pyrenees region (contact me by MP).
100g for one year? its little said therefore!

- a 0,7x0,6x0,25 full butcher's tray almost to the brim,
- a small solar "stirrer" made from an old disassembled hi-fi system and powered by a small solar panel taken from a Chinese HS fence energizer (photos available on request).
- a large pass,
- a marble slab for drying
- a pitcher
- a thermometer,
- Sunflower paper for pH
- white wintering fabric to shade if necessary.
- and of course, the eyes, nose and fingers.
That's it that's all !
Illuminated tank exposure but without direct sun, culture pH between 10 and 11,5 in brackish water.
We give "food" according to what we take (harvest approximately every three days on average in good season).
The "eat" is urine or nettle manure, iron salts (rather citrates if possible) and wood ash.
It is also necessary to have baking soda which is used to balance the pH and to provide dissolved CO2, which "boosts" the growth of algae.
The whole art consists in finding a sampling / feeding rhythm adapted to the conditions of the moment (lighting, temperature, etc.).
With a little experience, it is done very well "by feeling".
Here ! I hope it will give ideas!
Very interesting hmm. I had also thought of using a solar panel that can be found on ebay or in supermarkets, in order to supply a stirrer (magnetic or mechanical) and the "bubbling" via an aquarium pump. However, I thought of something else: always used this solar panel, but assemble the agitator with the bubbler: in other words stirred the water while oxygenating it (or rather providing it with the necessary CO2 lol), thus avoiding losses unnecessary in a pump; a bit like a water mill or this time it is the mill which moves the water and not the other way around = water and air are thus stirred together. It is still necessary to adapt it to PhotoBioreactor!

Ahmed offers moringa that I didn't know:
http://fr.wikipedia.org/wiki/Moringa
http://en.wikipedia.org/wiki/Moringa
It is a miraculous plant !!

Moringa oleifera leaves help fight malnutrition and its associated diseases (blindness, etc.). [1]
Moringa leaves contain twice as much protein as yogurt, 3 times more potassium than bananas, 4 times more calcium than milk, 7 times more vitamin C than oranges and 4 times more vitamin A than carrots, and would contain the 8 essential amino acids.
However the World Health Organization has refused to recognize the leaves of this plant as a legal nutritional supplement as a precautionary principle (lack of analyzes). [2 ....
In traditional medicine, all parts of the plant but especially the leaves have many applications: anti-diabetic, anthelmintic, skin care, strengthening of immune defenses ... The roots contain, among other things, a powerful antiseptic.
Moringa species can also provide oil for making biofuels. The seeds contain 30-50% oil, or 112-185 gal / acre / year. The oil contains 65-75% oleic acids and, unlike Jatropha oil, is also beneficial to humans.
Moringa species are drought-resistant and can grow in a wide variety of poor soils, even barren soil, with soil pH between 4.5 and 9.0. Although current cultivars can withstand frost, they do not generally survive a hard freeze. They can probably be grown wherever oranges grow successfully.

In our latitudes, something that works as well as everywhere else, it is the germinated seeds ... Fabulously rich in nutrients (several tens ... several hundred times what the mature plant has ...> normal, it needs what it takes to get there ...!) and no tra-lä-lä ... just water and room temperature in your apartment ...
Only constraint to respect in addition to giving them the amount of water they need: some grow in total dark while others like the light ... (If possible, take rainwater and not from the tap )

The trick is to soak them in water for the duration "that is going well", then after this pre-germination stage where they soak: we just rinse them twice a day (because once germination is gone, no need to drown them ...). If you don't have rainwater, you can filter it and let it sit in a jug. End of HS:
There are some who know the trick: watch out for the birds! (when the temperatures are mild outside ...)
