Croissance en autotrophie et en mixotrophie de la microalgue Micractinium pusillum Fres. isolée d´un lagunage naturel : influence de la lumière et de la température

Abstract: Dans le but d'étudier la dynamique des microalgues dans le lagunage naturel de Ouarzazate (sud du Maroc) et éventuellement sa modélisation, nous avons eu recours à la détermination des paramètres de croissance (µmax, Iopt et b) selon le modèle de PEETERS et EILERS (1978). À cet effet, Micractinium pusillum, algue verte Chlorococcale se développant dans les bassins de lagunage de la station pilote de Ouarzazate, a été isolée et mise en culture sur milieu synthétique (DAUTA, 1982) enrichi en azote et en phosphor… Show more

“…Both media containing organic phosphorus and carbon sources, as well as inorganic phosphorus and carbon sources, lead to important yield of EMn and biomass. This could indicate a mixotrophic metabolism, which is known to provide a better yield of energy production than autotrophic metabolism [43,44], increasing then the biomass yield and the synthesis of complex compounds, such as marennine. Note that in addition to modifying the overall physiology of H. ostrearia, using an organic medium could increase the production costs.…”
