Five large scale ponds, three ~1000L and two ~4500L , have been installed and are growing microalgae as part of the Marine Algae Industrialization Consortium (MAGIC). The ponds will grow ~10 strains of microalgae to compare their growth characteristics, algae biochemical signatures, and product suitability across a range of potential […]

The North Pacific Ocean (between approximately 0°N and 50°N) contains the largest continuous ecosystem on Earth. This region plays a vital role in the cycling of globally important nutrients as well as carbon. Although the microbial communities in this region have been assessed, the dynamics of viruses (abundances and production […]
In this study, we investigated the environmental impacts of scallop culture on two coastal estuaries adjacent the Bohai Sea including developing a quantitative PCR assay to assess the abundance of the bacterial pathogens Escherichia coli and Vibrio parahaemolyticus. Scallop culture resulted in a significant reduction of nitrogen, Chlorophyll a, and […]
In spite of challenging weather, the Duke Marine Lab hosted about 500 visitors for it’s 2017 Open House extravaganza. The Marine Microbe Group presented 3 exhibits including examples of ocean acidification, phytoplankton/algae in the coastal ocean and a demonstrating the large scale of production of microalgae for food and fuel. […]
The Duke Marine Lab joined the Beaufort NC July 4th parade to promote it’s upcoming open house. Lead by REU student Ford Fishman, the R/V Richard Barber was paraded through the streets to cheering residents and visitors alike!
ZIJ presented on the diversity and activity of Prochlorococcus at the OCB2017 summer meeting at WHOI in Woods Hole, MA. The presentation, “Ribosomal RNA and DNA (23S) of Prochlorococcus reveal variable activity and abundance relationships across taxonomic ranks” was based on a study with lead author and former student Alyse […]
Thraustochytrids are unicellular fungi-like (heterotrophic) marine protists and have long been considered to play an important role in the biogeochemical cycles of the coastal oceans. However, the significance of their ecological functions and diversity in marine ecosystems remain largely unknown. In this report, we examined the spatial and temporal variations […]
