1. Berbelin blue-I (N.N.′-Dimethylamino-p, p′-triphenylmethane-o″-sulphonic acid) has been examined as a reagent for the detection of manganese oxidation and manganese reduction in microbial culture media. 2. Berbelin blue in slightly acid solution may be added to media without influencing population growth of micro-organisms. The oxidation of Mn II solutions to Mn III and IV is detected by occurrence of deep blue colours. 3. In case of long-term culture experiments, it is more advisable to add Berbelin blue-I solutions only after cultivation. 4. Berbelin blue-I solutions react with manganese IV–VII in pH ranges between 3.5 and 10, thus allowing tests at desired pH values. 5. Reduction of manganese VII or manganese IV by micro-organisms may be detected by addition of Berbelin blue-I solutions after cultivation periods. White halos within dark-blue coloured media indicate reduction of Mn-IV compounds better than occurrence of white spots in slightly violet or grey media, as produced by the incorporation of manganese oxides or permanganate solutions to test media. 6. Ecological work and quantitative work on board research vessels is much easier and less dangerous with Berbelin-I solutions than withFeigl's Benzidinium reagent. 7. Berbelin blue-I may be used for quantitative determination of manganese and oxygen when measuring optical density of the colour complex at 618 nm in wide concentration ranges and working in acetate buffer.
