Sulfur-metabolizing symbioses are typically found in highly reducing habitats, because their symbiotic bacteria need to have access to reduced sulfur compounds to drive chemoautotrophy (Johnson et al.
After examining the carbon-13 and nitrogen-15 contents of the clam and mussel tissue, Steve Macko (University of Virginia) suggested that the clam derives all its nutrition from chemoautotrophy, while the mussel utilizes other energy sources as well (perhaps by feeding directly on whale-bone organics).
We compared its genome annotations and available biochemical information with those of other representative organisms related to chemoautotrophy (which include Thiomicrospira denitrificans, Hydrogenobacter thermophilus, and an archeaon--Pyrobaculum aerophilum), and extracted and integrated relevant information to formulate a canonical metabolic chart.
Apart from chemoautotrophy and suspension feeding there is a third possible strategy, epidermal uptake of dissolved organic matter (DOM).
