Fluoride-induced filaments of Erwinia carotovora.
Sodium fluoride induces filamentous growth of Erwinia carotovora when it is grown in liquid media containing aspartic acid only as the sole source of nitrogen. It is proposed that a stable complex of F(-)-Mg2+-enzyme and PO2(4) resulting in Mg2+ deficiency and consequent inability of E. carotovora cells to oxidize aspartic acid normally, is responsible for the formation of filaments in the presence of fluoride ions.
