Influence of different Carbon and Nitrogen Sources on the Production of Single Cell Biomass from Potato Peels

Abstract

Potato peel can be converted into various value-added compounds, such as enzymes, bio sorbents, biohydrogen, and biogas. Objective: To evaluate the influence of different Carbon and Nitrogen Sources on the Production of Single Cell Biomass from potato peels. Methods: The process of fermentation was carried out in mix broth with different concentrations of carbon, nitrogen, and different nitrogen sources to determine the effect of these factors on the production of SCP. Results: Maximum yield of dry cell biomass (0.251 and 0.245 g/100 ml) was achieved with organic nitrogen source peptone and inorganic nitrogen source ammonium sulphate, respectively. Ammonium sulphate is more suitable to use as peptone is expensive organic nitrogen source. Next optimization of nitrogen concentration was done with ammonium sulphate with different concentrations and best yield (0.190 g/100 ml) was obtained with 1.5% nitrogen concentration. Conclusions: In conclusion, the study suggests that ammonium sulphate is a more suitable nitrogen source than peptone for maximizing the yield of dry cell biomass. Additionally, optimization of nitrogen concentration with ammonium sulphate showed that a 1.5% concentration is the best for achieving the highest yield. These findings have important implications for improving the efficiency and cost-effectiveness of industrial-scale production of dry cell biomass
