FIG. 3.
Results of chemostat experiment performed with Flectobacillus sp. strain MWH38, showing the influence of growth rate on the morphology of the strain. Initially, bacteria were grown in both reactors at a growth rate of 0.5 day−1. On day 13, the growth rate of the bacteria in reactor 1 was increased to 1.0 day−1, and 9 days later the growth rate of the bacteria in reactor 2 was increased to 2.0 day−1. (A) Influence of growth rate on the percentage of long filaments (length, >10 μm) in the population. (B) Influence of growth rate on the mean bacterial length (including single cells and filaments). d, days.
