Abstract Lamprocystis roseopersicina was found to be the dominant phototrophic bacterium in meromictic Deadmoose Lake. Using carbon‐14 it was determined that phototrophic bacteria fixed 14.3 g C m −2 year −1 , 17.1 % of the total limnetic primary production. Experiments indicated low light intensities ( X = 8.87 × 10 −2 cal cm −2 hr −1 ) to be the most important factor limiting bacterial production. Lamprocystis was shown to be capable of photoorganoheterotrophic uptake of glucose.
