Bacteria in post-glacial freshwater sediments
Article Abstract:
Sediment bacteria play an important part in benthic food webs, nutrient cycling and decomposition of organic matter. Prokaryote communities found in post-glacial profundal freshwater sediment have been examined for culturability, viability and community structure. Many cells in upper sediments were metabolically active. Sulphate-reducing bacteria were not detected below 20 cm, but isolates showing denitrifying activity were detected at all depths.

Phylogenetic differentiation of two closely related Nitrosomonas spp. that inhabit different sediment environments in an oligotrophic freshwater lake
Article Abstract:
Research is conducted on the ammonia-oxidizing bacteria population in water and sediment seasonal samples recovered from a temperate oligotrophic lake. The presence of nitrosomonad DNA of the Nitrosomonas europaea-Nitrosomonas eutropha lineage in the lake is discussed.

Mosaic plasmids and mosaic replicons: evolutionary lessons from the analysis of genetic diversity in IncFII-related replicons
Article Abstract:
The nucleotide sequences of the alpha replicons from the pGSGH500 and pLV1402 plasmids are described. They are related to a group of replicons in the IncFII family and the broader family of antisense-control-regulated replicons .
