Researchers at Southern Cross University (SCU) have launched a significant research project aimed at reducing the cost of omega-3 supplement production by 50%. The initiative is designed to make these vital nutrients more accessible to pregnant women and infants in low-income nations by bypassing traditional fish oil in favor of the primary nutrient source: marine microorganisms.
Led by Professor Dirk Erler from SCU’s Faculty of Science and Engineering, the team is investigating how to cultivate omega-3-producing microorganisms more affordably through precision fermentation. This method involves using agricultural and food-processing by-products to provide the necessary sugars for growth, effectively replacing expensive traditional feedstocks.
Omega-3 fatty acids, particularly DHA, are critical during pregnancy and early childhood development, as DHA accumulates rapidly in the brain and retina during the third trimester. Research has also linked omega-3 supplementation to a lower risk of preterm birth. Professor Erler noted that cost remains the primary barrier to supplement uptake, and the project’s central objective is to eliminate this economic hurdle.
The research specifically focuses on marine microorganisms known as thraustochytrids. By growing these 'throstys' on land via precision fermentation, the researchers can produce omega-3 oils under controlled conditions. This approach offers a reliable, scalable, and targeted alternative to wild-caught fish oil, potentially stabilizing the global supply chain.
Biomedical scientist Dr. Nedeljka Rosic emphasized that the project aims to improve long-term health outcomes for women and children through simple dietary improvements. This 18-month initiative is supported by the Grand Challenges program of the Gates Foundation, marking the first time Southern Cross University has received funding from this prestigious organization.
