Abstract Two adjacent saline, meromictic lakes in Saskatchewan host different populations of phototrophic bacteria. Deadmoose Lake hosts a population of Lamprocystis roseopersicina (Chromatiaceae) while in Waldsea Lake a population of a Chlorobium species (Chlorobiaceae) is dominant. Differences in light quantity, light quality, temperature, pH and Lamprocystis' capacity for photoorganoheterotrophic growth explain why different genera of phototrophic bacteria are found within the two lakes. These phototrophic bacteria make a significant contribution to total photosynthetic productivity, fixing 14.3 and 32 g C m-2 year -1 in Deadmoose and Waldsea Lake respectively.
