Monoraphidium sp, HM 768826: A suitable sustainable lipid source for biodiesel production.

Due to diminishing fossil fuel reserves, it is necessary for us to shift for an alternative fuel source that could be sustainable and ecofriendly. Microalgae produce different ratios of lipids, proteins and carbohydrates. Microalgal lipid can potentially be employed for biodiesel production. Our research has demonstrated the total lipid content, fatty acid profile and biodiesel production from a naturally isolated strain of Monoraphidium sp. from fresh water pond. In the present study, the total lipid content was found to be 8.9% under normal nutrient conditions whereas it was increased to 23.1% under nitrogen deficiency conditions. The fatty acid profile showed the presence of high level of saturated and monounsaturated fatty acid than polyunsaturated fatty acid, which is optimum for biodiesel application. Biodiesel was produced from extracted algal oil by alkali-catalyzed transesterification. The pH of the produced biodiesel was found to be 8.1 and it was stored for further analysis. Moreover, we have partially characterized the isolate based on 18SrRNA sequence and submitted in GenBank with accession number as Monoraphidium sp. HM768826.
