Abstract

The present study was to investigate the effectiveness of using digested dairy manure as a nutrient supplement for cultivation of oil-rich green microalgae Chlorella sp. Different dilution multiples of 10, 15, 20, and 25 were applied to the digested manure and algal growth was compared in regard to growth rate, nutrient removal efficiency, and final algal fatty acids content and composition. Slower growth rates were observed with less diluted manure samples with higher turbidities in the initial cultivation days. A reverse linear relationship (R(2) = 0.982) was found between the average specific growth rate of the beginning 7 days and the initial turbidities. Algae removed ammonia, total nitrogen, total phosphorus, and COD by 100%, 75.7-82.5%, 62.5-74.7%, and 27.4-38.4%, respectively, in differently diluted dairy manure. COD in digested dairy manure, beside CO(2), proved to be another carbon source for mixotrophic Chlorella. Fatty acid profiles derived from triacylglyceride (TAG), phospholipid and free fatty acids showed that octadecadienoic acid (C18:2) and hexadecanoic acid (C16:0) were the two most abundant fatty acids in the algae. The total fatty acid content of the dry weight increased from 9.00% to 13.7% along with the i...Continue Reading
