Abstract
A study of the toxicity of epinigericin, an antibiotic ionophor, towar ds the ciliate Tetrahymena pyriformis showed that this molecule stoppe d cell division, increased cell volume and led to a more basic intrace llular pH. The action of epinigericin was probably linked to its funct ion as an ionophor. The ionic selectivity of this molecule is still no t known. The raising of the intracellular pH of ciliates by this antib iotic may be linked to its toxic action and its ion-transport mechanis m in Tetrahymena.
