SYNOPSIS. Paramecium multimicronucleatum was grown in a buffered desiccated lettuce medium maintained at pH 7.5, with Aerobacter aerogenes the main bacterial source. The maximum expansion in length and width was at pH 6.0; the minimum expansion in length and width at pH 8.5. The paramecia were usually stouter at pH levels 〈 7.0 except at pH 5.5 and generally more slender 〉 pH 7.0.The pH of the medium affected the size of food vacuoles as indicated by the fact that the maximum food vacuolar diameter was at pH 6.0, the minimum at 7.0.The fastest and greatest expansion of food vacuole diam. was at a relative viscosity of 8; the minimum food vacuolar diam. was in controls (without gum arabic) having a viscosity of 1.3.
