Bacterial density, biomass, morphological dive rsity and cell integrity were studied in surficial sediment samples taken form eight locations on the Romanian coast. Investigation was done by epifluorescence microscopy, employing SYBR Green I (universal fluorochrome) and propidium iodide (for visualising cells with damaged membranes). Cell density varied between 4.62-9.64 Г— 107 cells/cm3 sediment, showing a relation to sediment grain size. Dry biomass ranged between 3.03-6.39 Вµg/cm 3. Rod shaped bacteria were dom...
