Abstract

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.

胡萝卜欧文菌氟诱导细丝的研究。
在含天冬氨酸作为唯一氮源的液体培养基中,氟化钠诱导胡萝卜欧文菌的丝状生长。有人提出,F(-)-Mg2+-酶和PO2(4)的稳定复合物导致Mg2+缺乏,从而导致E. carotovora细胞无法正常氧化天冬氨酸,这是在氟离子存在下形成细丝的原因。
