Mean fluorescence intensity (sfGFP) in pellet of B. methanolicus recombinant strains carrying sfGFP gene. The sfGFP gene is fused to signal peptides from either G. stearothermophilus (strain spGs-sfGFP), B. subtilis (strain spBs-sfGFP), B. licheniformis (strain spBl-sfGFP) or B. methanolicus (strain spBm-sfGFP). Fluorescence from strain carrying vector pBV2xp-sfGFP with no signal peptide (sp0-sfGFP) is used as control. Fluorescence from both uninduced (black bars) and induced (grey bars) cultures are indicated
