Fig. 3From: Transmating: conjugative transfer of a new broad host range expression vector to various Bacillus species using a single protocolVisualization of sfGFP expression by fluorescence microscopy. Top row from left to right: Transmates of B. licheniformis, B. mojavensis and P. polymyxa carrying pBACOV-sfGFP. Bottom row from left to right: B. licheniformis, B. mojavensis and P. polymyxa wild type strains. The scale bar corresponds to 5 μm. Images were recorded using a Zeiss Axio Imager.M1 fluorescence microscope equipped with a Zeiss AxioCam MRm cameraBack to article page
