C27 can perform mixotrophic growth in denitrifying sulfide removal (DSR) medium. Quantitative proteomics analysis on abundance of proteins of C27 under DSR reactions at C/N=1.26, 1.63 or 3.0 was conducted using isobaric tag for relative and absolute quantitation (iTRAQ) and bioinformatics techniques. A total of 181 proteins were noted differently expressed at different C/N ratios, which were classified on the basis of cluster of orthologous groups (COG) of proteins and gene ontology (GO) analysis. The abundance of differently expressed proteins first down-regulated and then up-regulated as C/N ratio was increased. Excess carbon supply stimulates C27 to enhance expression of proteins responsible to electron transfer, translation and membrane transport, so the strain can grow fast and defend toxicity of high levels of sulfide.COG function classification of the identified 181 differently expressed proteins.
