✦ Synopsis

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 x10-2 cal cm-2hr-1) to be the most important factor limiting bacterial production. Lamprocystis was shown to be capable of photoorganoheterotrophic uptake of glucose.

Predatory bacteria that attack Chromatiaceae (purple sulfur bacteria) recovered from Lake CisΓ³ (a mostly anaerobic holomictic lake) have been studied over two annual cycles. During the mixing period the lake was completely anaerobic; both predator and prey populations were found along the water colu
