SCANNING ELECTRON MICROSCOPY INVESTIGATION OF BACTERIAL COLONIZATION OF MARINE BEACH SAND GRAINS
Journal Title: Baltic Coastal Zone - Year 2006, Vol 10, Issue 1
Abstract
Scanning electron microscopy was employed for the investigation of bacteria living on sand grains in a sandy marine beach in the Gulf of Gdansk (southern Baltic Sea). Bacteria colonize the sand grains; individual topography and shape of the grains were decisive for the colonization. Grains of diverse topography characterised by a great irregularity of shape were preferred, and protected surface sites were favoured. Many of the attached bacteria were found to produce polymer secretions; entire colonies attached by means of polymer nets were observed. A significant morphological diversity of bacteria in the vertical profile of the beach was determined. Bacteria inhabiting the sand grains showed the ability to reproduces
