IIT (BHU), Integral University team develops cost-effective method to grow microalgae for higher biofuel yield, boosting clean energy efforts

VARANASI: In a step towards cleaner and cheaper energy, researchers from IIT (BHU) Varanasi and Integral University, Lucknow, found a new way to grow microalgae that can produce more oil for making biofuel.

Biofuel is an eco-friendly alternative to petrol and diesel.This research was done by a team led by Gyanendra Tripathi, under the guidance of Vishal Mishra, School of Biochemical Engineering from IIT (BHU), and Alvina Farooqui from Integral University, Lucknow. Their work was published in the science journal Green Chemistry Letters and Reviews.The team used a two-stage system. First, algae is grown in a closed tank called a photobioreactor, and then it is shifted to an open pond where it produces more oil.

This method helped increase the oil content in the algae using a special strain called Scenedesmus sp. GTAF_01 IU.“This method gives better results at a lower cost and can be used on a large scale. It will help in making clean fuel, protect the environment, and reduce dependence on fossil fuels,” said Vishal Mishra. The research supports the global goal of providing affordable, clean energy and protecting the planet from climate change.

If used widely, this method can help India move towards a greener, low-carbon future.“Our approach makes biofuel production more practical and sustainable. By using natural resources wisely, we can take big steps towards energy security and environmental protection,” said Alvina Farooqui.Prof. Amit Patra, Director, IIT (BHU), said, “This work is a fine example of how collaborative research can provide innovative solutions for society’s pressing needs. I congratulate the team for developing a method that aligns with our nation’s vision for clean and renewable energy.”
