Bacteriological investigations of the sandy beach ecosystem in Sopot

100%

Olańczuk-Neyman K. , Jankowska K.

tom No. 40 (2)

137-151

The paper presents the results of bacteriological investigations relating to the coastal seawater and sandy sediments along the beach in Sopot in an area between the mouths of two streams, Grodowy Potok and Kamienny Potok. The sandy sediments investigated at four sites along a transect perpendicular to the shore contained variable numbers of saprophytic bacteria. In areas close to the littoral zone large numbers of allochthonous bacteria were found. With increasing distance from the waterline their domination declines to the advantage of autochthonous bacteria, an indication of the decreasing influence of anthropogenic pollution.

Studies on the spatial and vertical variability of saprophytic bacteria abundance and their physiological properties were carried out in Sopot (the Gulf of Gdańsk) during the summer of 1998 at four different points along a transect perpendicular to the water line. Colony forming units (CFU) bacterial counts reached 104-106 g dry wt. of sediment -1. Bacteria were most abundant in the dune, and least abundant in the beach sand. Halotolerant bacteria were more numerous than limnotolerant ones. Ammonifying and uric acid decomposing bacteria constituted the most abundant physiological groups; sulphate reducing bacteria were least numerous.
