From: Hydrogen production by the hyperthermophilic bacterium Thermotoga maritima part I: effects of sulfured nutriments, with thiosulfate as model, on hydrogen production and growth

Fig. 1

Comparisons of different sulfured nutriments on Thermotoga maritima cultures. All sulfured compounds were added at the rate of 0.3 mmol L−1 sulfur equivalent in a medium containing glucose (25 mmol L−1), yeast extract (1 g L−1), and salts (see “Methods” section). DMSO, S°, and Na2S meant dimethyl sulfoxide, elementary sulfur, and sodium sulfide, respectively. Productivities of cells (Qcells), and of hydrogen (QH2), and consumption of glucose (Qglu) were calculated during the growth phase (after 14.5 h of incubation). All batch cultures were performed in triplicate in serum bottles. The control corresponded to T. maritima grown without adding the sulfured compounds
