Rapid screening for freshwater bacterial groups by using reverse line blot hybridization

Article Abstract:

Research discusses the usefulness of oligonucleotide probes targeting 16S rRNA genes for the identification of phylogenetic clusters in freshwater bacteria. The probe is tested with 81 North and West European lakes in a reverse line blot hybridization. Results show that actinobacterial clusters and verrucomicrobial clusters form at least 90% of the lakes tested.

Microbial biogeography along an estuarine salinity gradient: combined influences of bacterial growth and residence time

Article Abstract:

The hypothesis that estuarine bacterioplankton include populations originating in freshwater and marine environments, is examined. An investigation of the development of a unique estuarine bacterioplankton community and its dependence on the growth rate of the bacterioplankton community and the residence time of that community in an estuary is made.

Bacterioplankton community shifts in an arctic lake correlate with seasonal changes in organic matter source

Article Abstract:

Research shows that during a two year season a relationship is observed between the seasonal shifts in bacterial production and the quality of the terrestrially derived dissolved organic matter and between seasonal variation to bacterial production and bacterioplankton composition at Toolik Lake and its primary stream.
