Seminar Title: Investigating Carbon Metabolisms of coastal Marine Bacteria
Abstract: There are 1 billion bacteria in each liter of sea water in the ocean. Their metabolisms are constantly changing and manipulating the pool of dissolved organic carbon compounds (DOC) in the ocean; therefore, bacteria determine the fate of 662 Gt of DOC in the ocean which is comparable to the 720 Gt of Carbon dioxide in the atmosphere. Although marine bacterial respiration has such a profound influence over a large pool of carbon on the planet, the details of their carbon biogeochemical activities are not well understood. Laboratory culture experiments can help answer questions like how do marine bacteria respond to organic carbon? While tools like metagenomics can provide a picture of the entire bacterial community and their genes that manipulate and process DOC? Research efforts seeking to put the puzzle pieces together of DOC molecules and their relationship to marine bacteria have the potential to improve our understanding of the way the DOC pool changes in response to bacterial metabolisms.
