USING AN ALTERNATIVE MEDIUM (MOLASSES, YEAST SACCHAROMYCES CEREVISIAE AND NPK) FOR CULTIVATION OF CHLORELLA SP.Khadeejahkhadem Huraib and Sadeem M. Al-BarodyAbstract The green alga Chlorella sp was inoculated with different concentrations of culture media ranging from 125 to 450 mg/ml. The nutrients of the culture media (Molasses, yeast and NPK) seemed to be used by a Chlorella sp, it used them for its growth (increasing biomass, chlorophyll a content and cell number of Chlorella sp) that was weekly recorded, for a period lasted five weeks at the laboratory conditions. Chlorella sp gradually increased in such a way depends on the ascending concentrations of the medium, it started a growth increase after eight and four days in 125 and 250 mg/ml medium concentrations respectively. While in 350 and 450 mg/ml medium concentrations, the growth increased from the beginning of the experiment. Chlorella sp chlorophyll a content and biomass values in Ch 10 medium were very low in comparison with ones of different concentrations of the medium. No growth in control (D.W.) had occurred. |
