Abstract

A simple method for screening bacteria for diacetyl and acetoin production was developed. This method is based on the ability of diacetyl and acetoin to form a red insoluble complex with α‐naphthol in the presence of creatine. Addition of carboxymethyl‐cellulose containing calcium citrate in the medium allowed discrimination between citrate utilizing and non‐utilizing bacteria.

The production of N, and N,O from NO,-N can provoke a loss of nitrogen from agricultural land. However, in the case of excessive nitrate it can avoid water pollution. A method for counting the producers of N, and N,O from nitrate in soil, based on the isolation of colonies grown on plates prepared f
