+, indicates positive result; −, indicates negative result. Two symbols indicate different results for oxidation and growth (oxidation/growth).

Source of enrichment: Ref. (Budinoff & Hollibaugh, 2008).

Data from Hoeft et al. (2007) and Schneider (2012).

Growth on thiosulfate was reported by Hoeft et al. (2007), but we have been unable to grow this organism on thiosulfate in our laboratory.

All thioarsenate mixture was converted to monothioarsenate, but not completely oxidized to arsenate.

Reported in van Lis et al. (2013).

Previously reported as unable to grow on arsenite (Budinoff & Hollibaugh, 2008).

ND, not determined.
