The objective of the present study was to evaluate heterotrophic bacteria capable of growth in the presence of different antibiotics and their mixture in such dynamic ecosystem as marine beach. Mixture antibiotics had the strongest inhibitory effect on the growth of bacteria inhabiting sand of studied beach. Culturable bacteria were more resistant to ampicillin than to novobiocin and tetracycline. Inhibitory influence antibiotics on growth bacteria inhabiting studied beach were in the following order: mixture antibiotics > novobiocin > tetracycline > ampicillin.

The study was carried out in the estuarine part of the Słupia River, which, for the most part, comprises the harbour channel. The results of the present study showed that the total abundance of bacterioneuston was higher compared to bacterioplankton. In these two groups of bacteria, dead bacterial cells were dominant. The total number of bacteria, as well as the number of live and dead bacteria was similar in the entire horizontal profile. The abundance of live and dead bacteria showed distinct seasonal variation.

Antibiotic resistance of genus Aeromonas spp. isolated from seawater and sand of marine recreation beach located on the southern coast of the Baltic Sea was studied. The results of the present study showed that planktonic and benthic Aeromonas spp. inhabiting sand and seawater of the studied beach strongly differed in the resistance level to tested antibiotics. These microorganisms were the most resistant to amoxicillin, ampicillin, clindamycin and penicillin. All planktonic and benthic Aeromonas spp. strains were susceptible to neomycin and streptomycin. Bacteria inhabiting the dune were more antibiotic-resistant than bacteria isolated from other zones of the studied beach. The majority of bacteria inhabiting seawater and sand of the studied beach were resistant to 4-5 antibiotics of the 12 antibiotics tested. Planktonic and benthic Aeromonas spp. isolated from the Ustka beach were the most resistant to β-lactam and lincosamide antibiotics, while the most susceptible to aminoglycosides.

The results of the present study showed variability in resistance of FC bacteria isolated from beach sand and sea water against tested antibiotics. Enteric bacteria were the most resistant to clindamycin and penicillin while the most sensitive to ciprofloxacin, gentamycin, neomycin, rifampicin and streptomycin. Fecal coliform bacteria inhabiting sand were more resistant to nearly all tested antibiotics compared to bacteria isolated from sea water. The majority of bacteria inhabiting sea water and sand of the studied beach were resistant to only 1-4 antibiotics out of the 12 antibiotics tested. Fecal coliform bacteria isolated from Ustka beach were the most resistant to β-lactam and lincosamide antibiotics, while the most susceptible to aminoglycosides.

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.

The paper presents studies on level hydrolytic activity of extracellular enzymes in the surface microlayer and subsurface water in the coastal lake Dołgie Wielkie. The ranking order of the potential enzyme activity rates in the studied water layers was as follows: aminopeptidase > lipase > α-glucosidase > β-glucosidase. The level of activity of all studied hydrolases was higher in the surface microlayer than subsurface water. Activity of extracellular enzymes was influenced by the season.
