Bakterienzahl und bakterielle Aktivität in Wasserkörpern unterschiedlicher Belastung
The numbers of total and actively respiring bacteria were determined in samples of waste-contaminated Baltic sea and lake water. Both parameters were monitored by means of a new simultaneous direct count technique with the aid of a fluorescence microscope. The numbers of total and actively respiring bacteria were consistently higher in polluted samples. The total bacteria numbers were 102 to 104 times greater than plate counts. In addition, the total bacteria numbers showed lower variations from high polluted to low polluted samples than did plate counts. These observations also applied to the actively respiring bacteria. Smaller numbers of these bacteria were always registered for sea water than for lake water. The tendencies described above were better illustrated by the calculated biomass than by the corresponding detected number of bacteria.
