Abstract
Spirulina has proven itself in nutritional rehabilitation in countries where malnutrition is rampant
because it is rich in proteins, amino acids and essential fatty acids, vitamins and minerals.
Among the key factors to master in a culture of spirulina is the preparation of a culture medium
where all the ingredients should be available in a given region.
The objective of our study was to produce spirulina with 2 different culture media and compare
their effectiveness.
The study was carried out in the ENSSMAL experimental farm, and made it possible to optimize
the culture conditions and to monitor the physico-chemical parameters of the culture.
The medium tested (LMK) produced 33% more spirulina than the reference medium (HIRI). This
result can be disputed given the previous works which demonstrate the efficiency of use of the socalled HIRI medium, characterized by containing Natron. However, our work has demonstrated that
LMK medium can be easily used to produce spirulina under conditions where Natron is lacking.
