Abstract

A direct microscopic method based on the response of bacterial cells to inhibition of DNA synthesis by nalidixic acid in the presence of growth-supporting yeast extract and designed to determine the number of viable bacteria, was tested in marine sediments bioturbated by the deposit-feeding polychaete Arenicola marina. The number of responsive cells in sediment samples ingested and egested by the polychaete, reflected similar differences and trends as total direct counts or plate counts. Nevertheless, application of that viable direct count technique in marine sediments suffered also from considerable systematic errors.
