Chemical interactions between marine macroalgae and bacteria
There is a strong need to investigate the bacterial communities living on different coexisting macroalgae using new technologies, but also to investigation the production, localization and secretion of the biological active metabolites involved in those possible ecological interactions.
Molecular analysis of the distribution and phylogeny of the soxB gene among sulfur-oxidizing bacteria - evolution of the Sox sulfur oxidation enzyme system.
The soxB gene was detected in all investigated photo- and chemotrophic species that form sulfur globules during thiosulfate oxidation, and the SoxB phylogeny reflected the major 16S rRNA gene-based phylogenetic lineages of the investigated SOB, although topological discrepancies indicated several events of lateral sox B gene transfer among the SOB.
The family Chromatiaceae

Bacterial communities associated with the brown alga Laminaria saccharina from the Baltic Sea and from the North Sea were investigated using denaturing gradient gel electrophoresis and 16S rRNA gene clone libraries, indicating a specific association of bacterial communities with different parts of the alga.
Phylogenetic taxonomy of the family Chlorobiaceae on the basis of 16S rRNA and fmo (Fenna-Matthews-Olson protein) gene sequences.

- 1 July 2003
A new taxonomy of the green sulfur bacteria is proposed, based on phylogenetic relationships determined using the sequences of the independent 16S rRNA and fmo (Fenna-Matthews-Olson protein) genes,…
Phylogenetic and functional marker genes to study ammonia-oxidizing microorganisms (AOM) in the environment
This review presents an overview of approaches that have been used for the molecular study of ammonia oxidizers and discusses their application in different environments.
Phylogeny and distribution of the soxB gene among thiosulfate-oxidizing bacteria.

Comparison of soxB phylogeny and 16S rDNA phylogeny points to the significance of this gene transfer in hydrothermal vent bacterial communities of the North Fiji Basin.
Quinones of phototrophic purple bacteria

- Biology
- 1 November 1984
The quinone composition of the recognized species of the phototrophic purple nonsulfur bacteria, the Ectothiorhodospiraceae, and some Chromatiaceae species has been determined and Rhodoquinone is present in Rhodospirillum rubrum and Rhodospira photometricum.
The influence of ultramafic rocks on microbial communities at the Logatchev hydrothermal field, located 15 degrees N on the Mid-Atlantic Ridge.
The ultramafic-hosted Logatchev hydrothermal field (LHF) on the Mid-Atlantic Ridge is characterized by high hydrogen and methane contents in the subseafloor, which support a specialized microbial…
Abundance and Bioactivity of Cultured Sponge-Associated Bacteria from the Mediterranean Sea

- Biology, Environmental ScienceMicrobial Ecology
- 2007
One single alphaproteobacterium, which was related to Pseudovibrio denitrificans, was shown to dominate the cultured community of at least six of the sponges and is probably evolutionary young and facultative and possibly involves biologically active secondary metabolites.
