| Popis: | Recent research suggests that corals including cold-water corals harbor a diverse community of bacteria that are not only pathogens but also potential mutualists. Here we review data on bacterial community composition and diversity on the main cold-water corals framework builder species: Lophelia pertusa and Madrepora oculata. Sampling strategies such as box core, video grabs and remotely operated vehicle did not reveal strong differences between bacterial community composition as long as samples were used that looked ‘not contaminated’. However, there were strong differences of bacterial diversity between the two coral species. An analysis of bacterial community composition by pyrosequencing of L. pertusa and M. oculata revealed for the Mediterranean Sea the presence of the potential mutualists already found in the Atlantic indicating a species-specific core microbiome. The data also suggest some biogeographical differences between the Mediterranean Sea and the North Atlantic for both coral species, however, this depends on the phylogenetic levels applied. In addition, there was also indication for a shared microbiome between the Mediterranean Sea and the Atlantic. Therefore species-specific bacterial associations seem to exist, whereas the biogeographical variability can be seen as adaptation to specific environmental conditions. |
