BIOMASS AND BIOCHEMICAL COMPOSITION OF Chlorella Sp AND Scenedesmus apiculatus IN CULTURE

Microalgae are photosynthetic microorganisms with great potentialities that can be used in several fields. In Morocco, the microalgae sector is very little developed; it is mainly based on the exploitation of the raw material. For better exploitation of the benefits of microalgae, a study of the biochemical composition of two species, Chlorella sp and Scenedesmus apiculatus was carried out according to growth stages.

Our results show that protein in Chlorella sp can register 19.97% against 1.85% for Scenedesmus apiculatus, carbohydrates Chlorella sp still registers the highest value 5.78% against 0.33% for Scenedesmus apiculatus About lipids Chlorella sp has the highest content 0.31% against 0.11% for Scenedesmus apiculatus. Therefore, both strains are of interest to the food and pharmaceutical industries and constitute a vegetarian alternative with high dietary value to currently consumed products.
