| Strains | B.megaterium WH323 |
| Genotype | B.megaterium WH323(lacZ-,xylA::lacZ) was transformed with the plasmid pYYBm9 carrying the gene for a heterologous hydrolase from T.fusca (referred to as TFH) under the control of the xylose inducible PxylA promoter. |
| Culture medium | For all cultivations a defined minimal medium was used,containing the following components: 5 mM tricine, 520 uM MgCl2-6H2O, 276 uM K2SO4,50 uM FeSO4-7H2O, 1 mM CaCl2-2H2O, 100 uM MnCl2-4H2O, 50 mM NaCl, 10 mM KCl, 0.2%(w/v) (NH4)2SO4, 26 mM KH2PO4, 40 mM Na2HPO4-2H2O, 100 uL Antifoam 204 and 10 uL trace element solution per liter medium.The trace element solution contained 300 uM (NH4)6Mo7O24-4H2O, 40 mM H3BO3, 3 mM CoCl2-6H2O, 1 mM CuSO4-5H2O, 8 mM MnCl2-4H2O and 1 mM ZnSO4-7H2O.The medium was adjusted to pH 7 by adding 5 M KOH solution. |
