a The longest GY32 cell. b, c Longitudinal and cross-sections of GY32 observed with TEM. CM cytoplasm membrane, CW cell wall, SL S-layer. d Structure of the surface layer and appendages observed with TEM. e, f AFM adhesion maps of GY32 cells and appendages. F is a zoom-in of the white square in (e). g AFM height profiles of the cell (top) and appendage (below). h Representative cell of strain GY32 observed with TEM.
