Abstract
THIS investigation was prompted by the fact that though the effects of gibberellic acid and its salts in stimulating growth of plant cells have been studied widely1,2,3, very little is known of their effects on bacteria and other micro-organisms4,5. The first micro-organism chosen for this study was yeast (Saccharomyces cerevisiae), but its growth was found to be unchanged by potassium gibberellate (‘Gibrel’, supplied through the courtesy of Merck and Co., Inc.). It was then decided to study a unicellular animal, and the ciliate infusorian, Paramecium multimicronucleatum, was selected as being a simple, easily measured organism.
