Effect of yeast concentration on T. maritima growth cultivated with glucose (60 mmol/L) and in the presence (0.12 mmol/L) or absence of thiosulfate. (filled circle) Maximal biomass obtained in presence of thiosulfate. (open circle) Maximal biomass obtained in absence of thiosulfate. These cultures were performed in triplicate in bioreactor. Biomass yield on yeast extract (0.673 g biomass/g yeast extract) was evaluated from a linear regression (\(673\; {\text{Yeast}} + 36.1\)). The linear regression \((113.2\;{\text{Yeast}} + 3.1)\) was obtained in absence of thiosulfate
