Earlier, we discovered that induced reactive oxygen species (ROS) can be used to improve productivities of bioreactor cultures and to significantly improve biofuel yield. Many interesting, counter-intuitive biological phenomena have emerged from the extensions of the studies. 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.
Choose-Focus-Analyze (C-F-A) exercise
Students need to choose a problem of relevance to the industry or any human endeavour and analyze it using the principles learnt in class. This is an open-ended exercise and designed to develop the skills of choice, focus and analysis in students. The evaluation will be based on originality in approach: 15%, focus level: 15%, depth of analysis: 20%, quantum of work: 20%, original contribution: 20%, presentation: 10%. A concise report submitted two weeks before the last day of classes will be evaluated. It will help if the problem is chosen well in advance and sufficient time, distributed throughout the course duration, is devoted.
