Utilization of different nitrogen sources by scenedesmus dimorphus

Microalgae cultivation has received much attention in biofuel researches as it possessed several advantages, including high photosynthetic efficiency as well as high growth rates and high biomass production compared to other energy crops. The present study aims to evaluate the possibility of using c...

The present study aims to evaluate the possibility of using chicken and cow manure as organic sources of nitrogen. In this study, the freshwater green microalgae Scenedesmus dimorphus was cultivated in growth medium at pH 6, 7 and 8, which was enriched with different concentrations of chicken and cow manure as nitrogen sources. The concentration of chicken manure and cow manure which gave maximum algal growth rates were 3.5% and 22.5% respectively. These two N concentrations were used for the outdoor algal mass culture in 10 L medium for 20 days. The algal biomass in the mass culture was harvested at the end of the experiments and their lipid was extracted in nhexane by using a Soxhlet extraction method. Results showed that the lipid yield produced by the alga when cultured in chicken manure was about 11.23% and 11.14% when grew in cow manure. This experiment showed that S. dimorphus can be grown in animal manure as their source of N.
