Fig. 4From: Cloning and expression of the sucrose phosphorylase gene in Bacillus subtilis and synthesis of kojibiose using the recombinant enzymeSDS-PAGE analysis of SPase expression in the fermentation process of B. subtilis with pBSMuL3-SPase in 3-L bioreactor. The band of SPase (56 kDa) is indicated with an arrow (M marker, CS culture supernatant, WCL whole-cell lysates, PCL precipitation of cell lysates)Back to article page
