DST, Government of India grants a total outlay of Rs.27 lakhs to Dr Imran Y Pancha

Utilizing photosynthetic microalgae to produce renewable biofuel

Dr Imran Y Pancha, Assistant Professor, Department of Biological Sciences, SRM University-AP, Andhra Pradesh has received an outstanding total outlay of Rs.27 lakhs from the DST, Government of India, to work on “Chemical modulator based microalgal biorefinery for the production of biofuels and bioproducts”. Dr Imran was fascinated by the potential of microalgae to reduce greenhouse gases (GHGs) as well as its ability to accumulate a high amount of energy reserved molecules such as lipids/starch in the cells. Through his research, Dr Imran will be understanding the mechanism behind this and also, exploit microalgae for biofuel production.

Due to the development of industrialization and modernization, global energy demand is continuously increasing. Given that the fossil fuel energy reserve is limited, and its utilization causes various serious environmental issues such as global warming and the accumulation of GHGs in the atmosphere, renewable energy obtained from various biomass is a potential alternative to reduce atmospheric GHGs and the dependency on fossil-based fuel. Microalgae is one of the promising resources among various biomass since it has a high growth rate and photosynthetic ability in comparison to other terrestrial crop plants. Microalgae also accumulate a high amount of lipids and carbohydrates in the cell. Moreover, these microalgae can be cultivated in wastewater or seawater, which avoids the food versus fuel debate.

Dr Imran explains, “Microalgae usually accumulate lipid under stress conditions such as nitrogen starvation, which results in lower biomass production, limiting the commercialization of algal biofuel. The present research’s primary objective is to uncouple growth and lipid production pathway in the microalgae using chemical modulators. Utilization of such chemicals is also effortless in large scale production compared to the standard starvation approach. The next aim is to develop a process to extract multiple products such as pigments, lipids, and carbohydrates from single microalgal biomass. The development of such a biorefinery approach will lower the overall cost of the process and make it more economical on a large scale. To conclude, the focus of the project will be on utilizing photosynthetic microalgae to produce renewable biofuel and other commercially important products in a biorefinery manner. Utilization of microalgae will not only help to produce green fuel but also help in reducing atmospheric carbon dioxide (CO2) which creates several environmental issues.”

Using the SERB-SRG grant, microalgal cultivation facility will be established at SRM university-AP. The long-term goal of Dr Imran’s research group is to understand the molecular mechanism behind the accumulation of energy reserved molecules in the microalgae. Understanding such mechanisms will help to develop sustainable technology for the production of renewable biofuels from microalgae.
