SDS 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)
