Abstract

Introduction: Microalgae have been enjoying the focus of several renewable energy researchers for past few decades, due to their high photosynthetic activity and lipid content. These lipid acts as a precursor for the production of biodiesel, a green fuel. Aim: The present experimental study was done to estimate the lipid prospect of microalgae growing in the wastewater of abandoned coal mining and open cast areas of Jharia Coalfield of Dhanbad district, Jharkhand, India. Methodology: The algae samples were collected from wastewater accumulated in different coal mining areas as well as from the municipality water bodies like pond and river. They were then morphologically analyzed under the microscope to identify the most prevailing algal species in the coal mining areas. Lipid was extracted from these species by the traditional Chloroform and Methanol method i.e., Bligh and Dyer method. Results: The species prevailing in the coal mine waste water were identified as Spirogyra and Oscillatoria. Estimation of the lipid content extracted showed the variation of lipid content from algae grown in mine water to the algae grown in river water and pond water. Algal biomass from coal mining areas contained 16.3% more lipid than the algal biomass from the pond water. Conclusion: The findings reveal the different algal species which are predominantly found in the coal mine waste water. It also gives an idea about the quantity of lipid that can be extracted from them. Thus, this experimental study gives an idea about the possible use of the barren wasteland of the coal mining areas for the algae cultivation, in order to generate the biofuel.
