Spirulina and conditions for planting.

This cyanobacterium is a natural source of high quality proteins, easily digested and absorbed. Spirulina contains more than sixty fundamental food substances: chlorophyll, carotenoids, enzymes, antioxidants, vitamin complexes, minerals, fatty acids and their proteins, vitamins and bioavailable minerals. It contains all the essential amino acids required by the body. The artisan production process could be summarized in the following steps: 1.preparation of the culture medium.

We will dissolve in water salts of : sodium bicarbonate, 8 grams per litre, sodium chloride 5 g/l, potassium nitrate, 2 g/l, dipotassium sulphate, 1 g/l, monoammonium phosphate, 0.1 g/l, magnesium sulphate 0.2 g/l, urea 0.02 g/l, calcium nitrate, 0.05 g/l or calcium chloride, 0.03 g/l and iron sulphate, 0.005 g/l, we will leave it to rest and collect the liquid without the deposit, in order to create the nutrients with which this algae feeds; 2.inoculation of the reactor. A small amount of concentrated culture is needed, which will be inoculated into a container called a reactor, inside which biochemical reactions take place; 3.The cultivation of this algae seems simple but depending on the technological and human resources, the supply of raw materials and the quality of the environment, the results will be more or less successful. For this algae to grow and reproduce, certain environmental conditions are required. These conditions or variables are: The luminosity: It needs shade or half shade, but never direct sun.

The temperature: It can vary between twelve degrees centigrade and thirty-eight degrees centigrade. The pH: It should be between nine and five and ten and five. The light-dark cycle: It will be twelve hours of light and twelve in the dark. Evaporation: It is advisable to keep the initial volume of the crop.

Agitation: It can be done manually or mechanically. The ideal is that the liquid is in permanent agitation, in order to obtain the maximum exposure to light of all the spirulina filaments, so that photosynthesis and reproduction take place.
