Fig. 1

Phase contrast images of Z. mobilis monoculture and co-culture with S. cerevisiae strain CEN.PK113-7D or E. coli strain K12. Used strains and conditions are as shown in white texts in the images. Abbreviation glu stands for glucose in the medium. It is to be noted that Z. mobilis strain in the co-culture vs yeast with 100 g/L glucose formed elongated filamentous structure, while other conditions did not induce such drastic morphological changes in Z. mobilis cells. Right-bottom panel and Zm6 vs K12 panel are enlarged images with scale bar 10 μm, while all other panel sizes are corresponding with the scale bar 10 μm, found in the bottom-middle panel. Black a in the right-bottom panel indicates bursting cell with membrane protrusion from the cytoplasm. b The lysed cell exhibiting lighter phase contrast than that of the live cells. c Elongated Z. mobilis cell. d Dead yeast cell
