ABSTRACT
The present paper provides results of a study on heterotrophic bacteria occurrence and quantity in the biofilm and subsurface water of lake Jeziorak Mary. Degradation of several polycyclic aromatic hydrocarbons (PAH's) (anthracene, naphthalene) by neustonic and planktonic bacteria have been examined. It has been discovered that some aromatic hydrocarbons were better decomposed by neustonic bacteria than by planktonic ones. Both Total Number of bacteria (TN) and heterotrophic bacteria number (TVC) were higher in the surface microlayer than in the subsurface water.
