Abstract

In the presence of citrate, some strains of lactic streptococci grow as long chains of innumerable cells. The results with citrate-negative and citrate-resistant variants suggest that citrate is involved in the cell separation system of the streptococci. Observations of the long chains under scanning and transmission electron microscopes suggest that citrate inhibits a certain step near the final cell separation, or that citrate can stimulate initiation of cell division at multiple sites, thereby leading to the cells in long chains.
