摘要
We have experimentally investigated size distribution of bacterial cells at the circumference of homogeneously spreading disk-like colonies formed by Bacillus subtilis, and found that the size distribution of bacterial cells shows lognormal. We have developed a phenomenological model based on the experimental results for the growth process of bacterial cells and confirmed that the model reproduces a lognormal distribution of bacterial cell size which is very close to our experimental result. Our results indicate that both the lognormal distributions of cell cycle and cell growth rate are essential for the lognormal distribution of bacterial cell size.
