The oxygen consumption of a sandy beach interstitial community was determined on four occasions (January, May, August, October) on the Gulf of Gdańsk (southern Baltic Sea). The study was carried out at four locations on the beach slope (littoral, waterline, splash zone and middle beach). Oxygen consumption varied from 158–159 cm3 O2 m−2 h−1 at the underwater site and waterline to 20–36 cm3 O2 m−2 h−1 in the middle beach. According to these data, interstitial organisms are able to utilize from 206 to 1641 mg of organic carbon per square metre per day. In general, metabolic activity decreased gradually from the waterline towards the middle beach, and a significant correlation was found between oxygen consumption and sediment water content. Changes in oxygen consumption on the beach slope were statistically significant.

Potential capability of heterotrophic bacteria to hydrolytic degradation different organic macromolecules in three water layers in the marine channel were determined. In studied channel hydrolysed proteins and lipids. The heterotrophic microflora decomposition chitin were represented by the least abundant group of these organisms. The highest number of bacteria hydrolyzing tested organic macromolecules isolated from surface microlayer. It was demonstrated that no significant differences in number of bacteria decomposition studied organic compounds existed between different parts of harbour. Bacteria isolated from the water studied channel in different seasons hydrolyzing organic macromolecules with different intensity.
