Fig. 3From: Comparison of enzymatic activities and proteomic profiles of Butyrivibrio fibrisolvens grown on different carbon sourcesSDS PAGE (a) and zymogram (b) of extracellular proteins of B. fibrisolvens 3071. Strain was grown on the following carbon sources: 1 - glucose, 2 - xylan, 3– xylan and glucose, 4 – xylose. The MW protein standard was in the range 11–245 kDa. The protein concentrations in samples loaded onto both gels above is illustrated by blue columns (c)Back to article page
