Estimation of correlation between total microorganism counts and dehydrogenase activity measurement in compost from anaerobic sewage sludge
Summary. The study presents a measurement method of dehydrogenase activity in composts from anaerobic sewage sludge. The results of measurements were later compared with the data obtained from assays of the total numbers of microorganisms (mesophilic and thermophilic bacteria, moulds and yeasts) using the method of flood culture. The authors examined the correlation between the two methods employed to assess the activity and the physiological status of microorganisms settling compost. The performed statistical analysis failed to show any correlations between the total number of microorganisms determined by the traditional and plate methods and the measurement of dehydrogenase activity. The determination of the total number of microorganisms does not provide a full answer to the question of the physiological status of microorganisms carrying out the composting process. Neither of the methods of dehydrogenase activity in composts can be used separately and optionally to complete activity and the physiological status of microorganisms settling compost estimate.
Key words: dehydrogenases, compost, anaerobic sewage sludge, microorganisms
