ETUDE COMPARATIVE DE DEUX TYPES D’EAU POUR LA CULTURE DE LA SPIRULINE ARTHROSPIRA PLATENSIS
Journal Title: Larhyss Journal - Year 2016, Vol 28, Issue 28
Abstract
A study was led to the laboratory in order to evaluate the growth of Arthrospira platensis, cultivated to basis of two types of water (spring water and water of drilling) and to identify the medium presenting the best output in terms of concentration in biomass. The cultures were carried out according to the same physical and chemical conditions with the mediums tests enriched in nutritive elements (medium of Zarrouk) and the mediums pilot not-enriched. After 21 days of culture, the daily growth rate of Arthrospira platensis was 21,03 % and 20,64 % respectively in spring waters (Banco) and of drilling (Blondey) enrich in nutritive elements. No significant difference was recorded (p > 0,05). On the other hand, the growth stocks day laborer noted in the culture medium notenriched, were significantly different (p < 0,05) with a rate from 52 % in spring water compared to the water of drilling where it amounts to 45 %. The temperature having remained constant with 22°C, the values of pH recorded during the experiment, presented tendencies similar and favorable for the culture of the cyanobacteria.
