Fig. 4: Single-cell morphology enables physical confinement to selectively favour elongated colony architecture.
From: Cell shape affects bacterial colony growth under physical confinement
a Growth assays indicate that P. sanguinis performs at par with rod-shaped bacteria across two different degrees of confinement (mean ± s.d., n = 3 technical replicates). b Measurements of the aspect ratios of bacterial cell bodies for all ten strains used in this study, measured from samples in the late exponential phase (n \(\ge\) 80 individual cells represented as lognormal distribution, with boxes indicating the means, and bounds of the boxes indicating ± s.d.). c Microbial growth under confinement, as described using a phase space defined by the relative change in biomass production under increased confinement (the relative biomass ratio) vs single cell morphology (mean ± propagated error for the relative biomass ratio, and mean ± s.d. for the single cell aspect ratio).
