Utilization of various amino acids and carbohydrates by neustonic and planktonic bacteria isolated from coastal Lake Dołgie Wielkie was determined. The highest percentage of the bacteria inhabiting this lake used proline and glutamine. Considerably higher percentage of neustonic bacteria (FL, SL) than planktonic (SUB) bacteria in their metabolic processes prefered the tested amino acids. The highest percentage of isolated bacteria utilized fructose and glucose. The majority of tested carbohydrates actively used neustonic bacteria isolated from surface layer (SL) than film layer (FL) and subsurface layer (SUB). There were no major differences in the intensity of assimilation of amino acids and carbohydrates between bacteria inhabiting particular parts of Lake Dołgie Wielkie.

W pracy przedstawiono wyniki badań dotyczących wykorzystywania w procesach metabolicznych aminokwasów i cukrów przez bakterioneuston i bakterioplankton wyizolowane z przymorskiego jeziora Dołgie Wielkie. Preferowanymi przez bakterie aminokwasami były prolina i glutamina, a cukrami – glukoza i fruktoza. Bakterie wyizolowane z badanych warstw wody z różną intensywnością przyswajały testowane aminokwasy i cukry. Znacznie większy procent bakterii neustonowych (FL, SL) niż planktonowych w swoich procesach metabolicznych wykorzystywał testowane aminokwasy. Większość badanych cukrów aktywniej przyswajały bakterie neustonowe wyizolowane z błony powierzchniowej (SL) niż z filmu (FL) i podpowierzchniowych warstw wody (SUB). Nie wykazano różnic w poziomie intensywności przyswajania aminokwasów przez bakterie zasiedlające poszczególne części jeziora Dołgie Wielkie.
