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
