TY - Type of reference TI - Test of the culture of spiruline biologic Arthrospira platensis in the firm Masoandro of Amborovy in the urban township of Mahajanga Madagascar AU - Benjamin Christian RAMILAVONJY RAMIANDRISOA AU - Herimampihonona Patrick RAZAKAMANITRA AU - Rivoharinala RASOANARIVO AU - Hery Lisy Tiana RANARIJAONA AB - The conception of the biologic culture of the spirulina of the species Arthrospira platensis is based truly on the survey and the use of inputs. The objective of this survey is to raise the topic utopian on the biologic spirulina, while using a contribution of inputs organic majority on the one hand an ethical agriculture responsible for the rigorous environmental norms and on the other hand a systemic and ethical approach in algo-ecological positive. For the methodology of the experimentation, two basins of 4m3 of every have been used of which one for the conventional culture while using the chemical inputs and the other for the biologic spirulina culture while using the manure of plant castor oil plant and the brewing of the banana skin. According to the results, 688 g and 348 g have been harvested respectively for the conventional culture and the biologic culture of the spirulina at the time of a first harvest. At the time of a microscopic observation, the conventional culture has a fast growth that presents a tight structure spirulina. While the one of biologic is slow with a baffled structure. The physico-chemical parameters different not meaningfully. While comparing the two surroundings, the conventional culture is richer in inputs that the biologic culture while observing the lack of carbon, a nourishing source for the development of the spirulina. In short, the biologic spirulina culture is a better complete food source of antioxidants, rich in plant origin protein. He/it provides a medical profit including the prevention and the treatment of the illnesses. She/it also participates in the sequestration of the atmospheric carbon and a source of motto.
