Tiny organisms in freshwater pools might hold the key to a sustainable future for Hawaiʻi. Researchers at the University of Hawaiʻi at Mānoa are excited about transforming microalgae into valuable resources for biofuels, medicine, and nutrition.
In a recent study published in the Plant Biotechnology Journal, experts from the College of Tropical Agriculture and Human Resilience explored the power of synthetic biology and metabolic engineering to boost local microalgae production. Microalgae are superb at capturing carbon dioxide and turning it into high-value compounds like lipids (oils) and terpenoids (organic chemicals). These compounds have many uses, from renewable fuels to lifesaving medications.
Zhi-Yan “Rock” Du, the study’s lead author, emphasized the advantages of microalgae. “They don’t compete with food crops for land or fresh water,” he said. The research aims to find ways to reprogram these organisms to produce more of these valuable materials more efficiently.
However, scaling up the production of microalgal products to compete with petroleum has been challenging. The UH team, along with graduate student Ty Shitanaka and co-principal investigator Samir Kumar Khanal, investigated how gene-editing tools like CRISPR/Cas9 could optimize metabolic pathways in the algae.
By adjusting the internal chemistry of the microalgae cells, researchers can help them accumulate more oil and health-boosting compounds without hindering their growth. Previously, this was a significant hurdle in bioengineering efforts.
Hawaiʻi’s sunny weather and coastal access make it a perfect spot for growing algae. “This could help Hawaiʻi build a more resilient, energy-independent economy,” Khanal noted. Combining microalgae production with treatments for wastewater or recycling agricultural byproducts could create a sustainable and profitable system.
This study also highlights the role of synthetic biology in creating new biological capabilities. Collaborators included Professor Krzysztof Zienkiewicz from the Nicolaus Copernicus University in Poland, with support from the National Science Foundation and the USDA’s National Institute of Food and Agriculture.
In terms of social trends, interest in eco-friendly practices is on the rise. Many users on platforms like Twitter and Instagram are sharing tips on sustainable living, sparking discussions around innovative technologies like those used in this study.
Hawaiʻi’s research showcases not only the potential of microalgae but also a pathway to a greener future. By leveraging science and technology, the islands could lead the way in sustainable energy and agriculture, setting an example for others to follow.
