Correlation between flocculant production and morphological changes in Rhodococcus erythropolis S-1

Some sugar carbon sources affect flocculant production and cell morphology of Rhodococcus erythropolis S-1. Fructose was the most favorable for flocculant production. The cells were elongated, while flocculating activity was low. The cells were rod-shaped when sucrose was used as the carbon source.
