Hainan_China focused on the concept of enriched nutrition for corals and their symbionts to resist bleaching caused by global climate change.
We have developed a nutritional enhancement strategy to strengthen coral/Zooxanthellae
against marine environmental stress, such as the elevation in temperature and acidification of seawater. Several nutrients were screened and vitamin B12
was selected as the essential nutrient. VB12
producing strain, Pseudomonas denitrificans
was used as cellular chassis and vgb gene from marine microalga Vitreoscilla sp
., which is mostly upregulated at low oxygen level, as biological part to minimize oxygen demand for effective VB12
production within the framework of synthetic biology. Coral polyps, Zooxanthellae
and probiotic P. denitrificans
constructs were grown on the microfluidic coral-in-a-chip for successful proof of our probiotic hopythesis. A mariculture tank was built in Sanya Institute of Coral Ecology, China, to grow our "super corals" with enhanced nutrition for a long term, continuous culture.
