Abstract

Microalgae are more promising feed stocks to their widespread availability and higher oil yields. As with any biological lipid,this is a potential feedstock for making the renewable fuel biodiesel. However, extracting and purifying oil from algae continues to prove a significant challenge in producing both microalgae byproducts and biofuel, as microbial oil extraction is relatively energy-intensive and costly. The aim of the research work is to produce biodiesel from micro algal species. Chaetoceros sp were identified for the research work and studied for their lipid, carbohydrate and protein content. The main aim of the project is to make use of the algae present in the water bodies and to extract the useful algal oil meant for biodiesel production to meet the challenges of fuel requirement in the present scenario. Microalgal oil was extracted from Chaetoceros sp. and the physicochemical properties were determined. The density, viscosity, acid value, saponification value and free fatty acids were recorded as 1.305gm/ml, 6.2mm2 /s, 2.5339mg/gm of oil, 173.56mg/gm of oil, and 0.71gm/100 gm of algae (Oleic acid). The fatty acid profile showed pentadecanoic acid (17.56%), 1.Nonadecenoic acid (20.1%), methyl palmitate (2.91%), methyl linoleate (12.07%), palmitic acid (1.97%) as major fatty acids.
