A Remark on Microorganisms in Lake Sediments with Emphasis on Polyphosphate-accumulating Bacteria

Bacteria which are able to store large amounts of phosphorus as polyphosphate (PP) under aerobic conditions and to release it under anaerobic conditions are utilized for the advanced treatment of sewage. This note presents some results which indicate that PP-accumulating bacteria which possibly participate in the immobilization and release of dissolved phosphate may also be present in lake sediments.
