Planctomycetes diversity associated with macroalgae.
This study provides the first report of the cultured diversity of Planctomycetes on the epiphytic macroalgae community and presents clear evidence of their nutritional and intimate relationship.
Community composition of the Planctomycetes associated with different macroalgae.
Sequencing of DGGE bands indicated that Planctomycetes communities were highly diverse, and some Operational Taxonomic Units seemed to be specifically associated with each macroalgae.
Antimicrobial Activity of Heterotrophic Bacterial Communities from the Marine Sponge Erylus discophorus (Astrophorida, Geodiidae)
The results show the potential of the bacterial community associated with Erylus discophorus sponges as producers of bioactive compounds.
rpoB gene as a novel molecular marker to infer phylogeny in Planctomycetales
Based on the genomes of 19 planctomycetes it was possible to determine the correlation between the rpoB gene sequence and the phylogenetic position of the organisms at a 95–96 % sequence similarity threshold for a novel species.
The antimicrobial activity of heterotrophic bacteria isolated from the marine sponge Erylus deficiens (Astrophorida, Geodiidae)
The high levels of bioactivity and the likely presence of associated genes suggest that Erylus deficiens bacteria are potential sources of novel marine bioactive compounds.
Rhodopirellula lusitana sp. nov. and Rhodopirellula rubra sp. nov., isolated from the surface of macroalgae.
Roseimaritima ulvae gen. nov., sp. nov. and Rubripirellula obstinata gen. nov., sp. nov. two novel planctomycetes isolated from the epiphytic community of macroalgae.
Planctomycetes and macroalgae, a striking association
The peptidoglycan-free cell wall of planctomycetes allows them to resist the action of several antimicrobial compounds produced by the macroalgae or other bacteria in the biofilm community that are effective against biofouling by other microorganisms.

The production of fibrillar material and the existence of the polar appendages suggest that this microorganism should occur in aquatic environments bound to substrates and could be associated with P. micans in natural marine habitats.
Some effects of copper on the dinoflagellates Amphidinium carterae and Prorocentrum micans in batch culture
The influence of copper(II) on some aspects of the cell physiology and biochemistry of the dinoflagellates Amphidinium carterae and Prorocentrum micans growing exponentially was examined in batch…
