The current aspect of interest is algal bio-fuels. Our research group works with Reactive Species (RS, that include Reactive oxygen, nitrogen, halogen, etc., Species), and use the understanding of them to improve the algal biofuel yield.
Earlier, we discovered that induced reactive oxygen species (ROS) can be used to improve productivities of bioreactor cultures. Many interesting, counter-intuitive biological phenomena have emerged from the extensions of that study. In addition, we developed a novel strategy of oxygen supply to aerobic bioreactors, which eliminates the gas-liquid transport resistance, one of the biggest challenges to oxygen supply, and employed it to improve productivities of viscous and shear-sensitive fermentations. Also, the cost is attractive (Re. 0.15 per kg of equivalent oxygen), and hence, this strategy can potentially be employed to improve aerobicity of any bioreactor.
Further, we developed novel biosorbents for toxic trace metal removal with high uptake capacities, and bioreactors for plant shoot culture; they resulted in patents.
