2-DGE gel sections comprising proteins extracted from M. barkeri grown at 37°C and 15°C. (A) Methyl-coenzyme M reductase subunit G protein (Mbar_A0893) conserved for each temperature (expression level at 37°C/expression level at 15°C, up 1.24-fold). (B) Proteasome subunit A (Mbar_A2503) upregulated at 15°C (expression level at 15°C/expression level at 37°C, up 2.87-fold). (C) Universal stress protein (Mbar_A0825) upregulated at 37°C (expression level at 37°C/expression level at 15°C, up 3.81-fold).
