Abstract

 

Utilization of various amino acids and carbohydrates by heterotrophic bacteria isolated from a sandy beach in Sopot, Poland, southern Baltic Sea coast, was determined. The most intensive growth of bacteria was observed in the presence of amino acids, while carbohydrates were utilized less actively. Differences in the utilization of individual amino acids and carbohydrates by bacteria have been determined. The highest capability to assimilate amino acids and carbohydrates was observed in bacterial strains isolated from the middle part of the studied beach. No major differences were determined in the intensity of assimilation of the tested compounds by bacteria isolated from the surface and subsurface sand layers. Bacterial utilization of amino acids and carbohydrates depended on the chemical structure of those compounds.

 

Key words: marine beach, bacteria, amino acids,  carbohydrates
