Research Description
Algal Biofuel Technology The choice of algal strains with fast growth and high lipid content can be used to reduce the production cost of biofuel. However, after decades of searching for robust microalgal strains, there has been no such strain reported yet. Therefore, we are interested to use genetic engineering tools for generating an ideal strain with favorite characteristics that can be explored to produce an economically viable biofuel on a commercial scale. The production of biodiesel from microalgae is now underway in many countries, demonstrating its potential as our future energy source. Currently, we are involved in enhancing the lipid (triacylglycerol content) in marine algae as a biofuel feedstock. Several types of biofuels can be produced from triacylglycerol-containing feedstocks. For example, biodiesel (mono-alkyl esters) by transesterification of the algal-oil or renewable diesel by hydrodeoxygenation of oil, which is similar to petroleum-derived diesel fuel. Thus, increasing the lipid feedstocks by engineering algal strains is our prime target for making algae as an economically viable source for biofuel production. The Department of Biotechnology and Reliance Industries Limited provide the financial support for this work.

Metabolic Engineering for Drug Biosynthesis Artemisinin-based combination therapies (ACTs) are considered to be most effective against drug-resistant malaria. The yield of artemisinin is low from native plant Artemisia annua. Therefore, we are interested to explore the biosynthesis of artemisinin in an alternative plant system by transforming the chloroplast genome with the mevalonate pathway and the nuclear genome with the artemisinin biosynthesis pathway. To execute this, we have generated transplastomic-MEV plants (with mevalonate pathway) via a biolistic method that produces excess pools of isopentenyl diphosphate (IPP). To divert this higher pool of IPP into artemisinin, we have retransformed the transplastomic-MEV plants with the Agrobacteriumcarrying artemisinin biosynthesis pathway. Double transformed (DT) tobacco plants were produced showing variable amount of artemisinin. These plants grew normally, flowered and set seed like wildtype plants in the greenhouse. DT tobacco plants, due to higher biomass and rapid growth, are able to produce a consistent, reliable and low-cost supplementary source of drugs for ACTs, needed for antimalarial treatment in India. This work was supported by the Department of Biotechnology and the Department of Science & Technology, India.

Metabolic Engineering for Hypoallergenic Latex We are interested in genetic engineering chloroplasts as well as nuclear genome of guayule to enhance the yield of natural rubber by removing the monomer substrate limitation. Guayule (Parthenium argentatum) is an important commercial crop of the rubber industry and its rubber is distinct from Hevea brasiliensis rubber due to its hypoallergenic properties (allergy causing proteins are absent). This work is supported by Panaridus Inc. USA and by The Ohio State University, in collaboration with Prof. Katrina Cornish, OSU, USA.
