Fermentation of omega-3 and carotenoid producing marine microorganisms

The objective of the thesis was to understand and develop the process of fermentation in marine microorganisms for the production of omega-3 fatty acids and carotenoids. Among marine microorganisms, thraustochytrids that belong to phytoplankton group was identified as sources of omega-3 fatty acids and other valuable co-products. In this research, more efficient and cost-effective production of omega-3 oils and other value added products was discussed by addressing the below key objectives. Fermentation strategy using lower cost raw materials, particularly carbon. Screening for new strains that can naturally produce high levels of PUFAs together with useful co-products that can be harvested along with the omega-3 oil.
