Quantification, frequency of dividing cells and production of planktonic bacteria in the Embalse del Río III reservoir. Related variables

During a whole year (1987-1988), monthly variations of biomass, frequency of dividing cells and production of bacterioplankton were studied in the Embalse del Río III Reservoir (Córdoba, Argentina). Algal biomass and production were measuredsimultaneously. A significant relationship between bacteria...

Related variables Cuantificación, frecuencia de división celular y producción de bacterias planctónicas en el Embalse del Río III - variables relacionadas Di Siervi, Miguel A. Mariazzi, Aldo A. Donadelli, Jorge L. During a whole year (1987-1988), monthly variations of biomass, frequency of dividing cells and production of bacterioplankton were studied in the Embalse del Río III Reservoir (Córdoba, Argentina). Algal biomass and production were measuredsimultaneously. A significant relationship between bacterial and algal production was observed, being temperature an important regulator factor. Bacterial biomass valúes did not correlate with their production rates. Low valúes and variability in the frequency of dividing cells were probably due to methodological difficulties for detecting división in very little cells. These data suggest that the frequency of dividing cells is not a reliableindicator of total active bacteria. Annually bacteria cycled nearly 60% of organic matter produced by phytoplankton in the water column.
