The artificial seawater recipe for 1 L of sterile H2O is in Table AT1 (ZoBell, 1946). The electron donors and acceptors added to the 1-L artificial seawater solutions to make culture medias are in Table AT2. The composition of Riddle Nickel Mountain peridotite used in the enrichment cultures and the SSA measurements are in Table AT3.
The amount of dissolved Li in media through time for the two culture sets measured and used to calculate the averages in Table T5 are in Table AT4 (plotted in Figs. F4, F6A, F6C, F6E, F6G, F6I, F6K, F6M).
The amount of dissolved Si in media through time for the two culture sets measured and used to calculate the averages in Table T4 are in Table AT5 (plotted in Figs. F5, F6B, F6D, F6F, F6H, F6J, F6L, F6N).
