Cobalamin, also known as Vitamin B 12 , is an essential part of life. It plays a crucial role in the ocean, regulating the metabolic activities of oceanic microbes, which in turn play dynamic roles in carbon cycles and subsequent atmospheric regulation. This research quantifies cobalamin production in two species of bacteria under high and low carbon environments, and in environments enriched with two compounds that may originate from other microbial community members and indicate cobalamin stress. Using liquid chromatography and mass spectrometry, this research shows that for most bioavailable cobalamin, both R. pomeroyi DSS-3 and Sulfitobacter sp. SA11 produce more but statistically insignificant cobalamin molecules per cell when g...
