Fig. 5From: Engineering Saccharomyces cerevisiae for improved biofilm formation and ethanol production in continuous fermentationA SEM images of biofilms formed on cotton fibers in three different regions after biofilm-immobilized continuous fermentation in a 2-L column reactor. B Images of biofilm formed on cotton fibers after biofilm-immobilized continuous fermentation coupled with membrane separation. C Images of cells remained on the separation membrane after membrane separationBack to article page
