The effect of Na2S2O3·5H2O on the carbon fixation capability of Thiobacillus thioparus(DSM 505) was determined by measuring the total organic carbon (TOC) concentrations under different concentrations of Na2S2O3·5H2O. In addition, the mechanism was clarified by analyzing the transcription characteristics of RubisCO-encoding genes (cbb genes) and the concentrations of extracellular free organic carbon (EFOC) under different concentrations of Na2S2O3·5H2O. The result showed that by increasing the concentrations of Na2S2O3·5H2O appropriately, the carbon fixation capability of Thiobacillus thioparus could be promoted and the ratio of extracellular free organic carbon to total organic carbon fell significantly. Moreover, the analysis from the transcription characteristics of cbb genes revealed that Na2S2O3·5H2O had no significant effect on the transcription efficiency and transcription pattern of cbb genes. So Na2S2O3·5H2O might improve the carbon fixation capability by promoting the cytoskeleton synthesis rate as electron donors to eliminate the inhibition effect of extracellular free organic carbon on the carbon fixation of Thiobacillus thioparus.
