RESUMO

Bacterioplankton represents a convenient model for studies of the effect of anthropogenic factors on an ecosystem. Structural and functional alterations in bacterioplankton induced by non-permanent pollution with low and high concentrations of organic matter (OM), chronic pollution with a low OM concentration, and combined pollution with mineral salts and OM was analyzed with the use of laboratory water flow models. The effect of low OM concentrations added at short regular intervals was the most significant. Stable alterations in the structure and metabolism of bacterioplankton were detected. The numbers of bacterioplankton and bacterial production significantly increased. Since bacterioplankton is the most sensitive and quickly-reacting component of biocenoses, its response can be analyzed to estimate alterations in water ecosystems induced by anthropogenic pollution.
