Organic manure (horses stool) affects the green alga Chlorella vulgaris Beijernick growth

Abstract

The green alga Chlorella vulgaris was inoculated with culture media of Chu-10 with or without different concentrations (0.5, 1, 1.5 and 2 gm l-1 dry weight) animal stools (manures) as an organic source of nutrient, for (12 days) at the laboratory conditions. The green alga utilized for growth, the phosphates and nitrates from organic sources rather than the phosphate and nitrate of the Chu 10 culture media. The culture media contains of 2 gm l-1 organic manure gave more Chlorophyll a contents (6.72 μg l-1) after 12 days of the inoculation and more growth (71.5 X 103 cells.ml-1) was detected after 4 days of inoculation than that of other treatments., which it means that media had more ability to survive. Horse stool as an organic sources, found to be a good and cheap media for food nutrition.
