We investigated the growth response of the heterotrophic prokaryotic community focusing on Vibrio- and Rhodobacter-related populations (SRF3) to variation in the availability of dissolved organic matter (DOM), population density-dependent effects, and prokaryotic virus (phage) infection in coastal and offshore waters of the NW Mediterranean...

A bacterial isolate from the Baltic Sea, BA131(T), was characterized for its physiological and biochemical features, fatty acid profile, G+C content and phylogenetic position based on comparative 16S rRNA gene sequence analysis. The strain was isolated from surface water of the central Baltic Sea during the decay of a plankton bloom....

Understanding structure-function links of microbial communities is a central theme of microbial ecology since its beginning. To this end, we studied the spatial variability of the bacterioplankton community structure and composition across the central Baltic Sea at four stations, which were up to 450 km apart and at a depth profile...

A bacterial isolate from the Baltic Sea, designated strain BA141(T), was characterized for its physiological and biochemical features, fatty acid profile, pigment spectrum, DNA G+C content and phylogenetic position based on comparative 16S rRNA gene sequence analysis. The strain was isolated from the surface of sediment in a deep basin of the...

Epidemics of Vibrio parahaemolyticus in Chile have occurred since 1998. Direct genome restriction enzyme analysis (DGREA) using conventional gel electrophoresis permitted discrimination of different V. parahaemolyticus isolates obtained from these outbreaks and showed that this species consists of a highly diverse population. A multiple-locus...

Bacterial community dynamics of a whole drinking water supply system (DWSS) were studied from source to tap. Raw water for this DWSS is provided by two reservoirs with different water characteristics in the Harz mountains of Northern Germany. Samples were taken after different steps of treatment of raw water (i.e., flocculation, sand...
