Figure 2From: Heterologous protein display on the cell surface of lactic acid bacteria mediated by the s-layer proteinGFP-LcsB binds to the surface of various lactic acid bacteria cells. The GFP-LcsB proteins were added to various LAB cells (Lb. delbrueckii, Lb. brevis, Lb. helveticus, Lb. johnsonii, Lb. crispatus, S. thermophilus, L. lactis and Lb. salivarius) and mixed for 1 hour. Then, the cells were collected, washed and resuspended in PBS. Subsequently, the cells were observed by fluorescence microscopy.Back to article page
