Abstract

The esterase isozymes of Paramecium aurelia grown in the presence and absence of bacteria were examined by starch gel electrophoresis. Where present, bacteria make a positive contribution to the esterase zymograms. Different bacteria contribute different esterases. Paramecia growing in axenic medium possess a different esterase which is not produced by the same parmecia growing in the presence of bacteria. This axenic esterase disappears when bacteria are added back to the medium.
