 abstract={The content of organic matter and calcium in bottom sediments were analysed, and also the calorimetry of sediments and organic matter from these sediments. An attempt was made to estimate the intensity of mineralization processes on the basis of oxygen consumption, treated for that purpose as an indicator. It was found that the calorific value of sediments is a good indicator of the trophy of lakes. The energy content of organic matter can be an indicator of the intensity of mineralization processes. Sediments from anaerobic environment have a considerably higher oxygen consumption than these from well oxygenated environment. The presence of bottom fauna increases the oxygen consumption of sediments.},
