Cultivation of Spirulina platensis in Fermented Corn Feed Residues

Abstract

The cultivation of Spirulina platensis in corn feed residue liquid fermentation medium of low cost diet with different ratios was investigated by a completely randomized design; CRD). The study was conducted on fermented water from corn residue (corn husks, corn stalks, and corn dust) at 20% with chemical formula. The study was found that the fermented water from the corn cultivar was the most suitable for use as a low cost medium for culturing Spirulina with an average OD of 0.450±0.006 cells/ml., average number of cells was 81.440±0.497 cells/ml., specific growth rate (µ) was 2.079±0.001 cells/day and average carotenoid content was 79.943±0.043 micrograms/g dry cell weight with significant differences were observed (P<0.05). The amount of fermented water from the corn stalks at 10, 15, 20 and 25% was studied. The results were showed that 20% of corn feed was the best formulation because an average OD was 0.434±0.020 cells/ml., the average cell number was 82.594±0.056 cells/ml., the average specific growth rate (µ) was 2.015±0.016 cells/day., the average carotenoid content was 75.026±0.006 micrograms/g.dry cell weight and the average protein content was 137.288±0.037% had significant differences (P<0.05).
