| nautella italica gen. nov., sp. nov., isolated from a marine electroactive biofilm. | five isolates obtained from a marine electroactive biofilm grown on a stainless steel cathode were investigated by using a polyphasic taxonomic approach. analyses of whole-cell fatty acid methyl esters and 16s rrna gene sequences showed that the isolates belonged to the roseobacter lineage of the class alphaproteobacteria. both phenotypic and genotypic analyses demonstrated that the five new isolates constituted a single species that did not represent a recognized member of the roseobacter linea ... | 2009 | 19329612 |
| celeribacter neptunius gen. nov., sp. nov., a new member of the class alphaproteobacteria. | a whitish gram-negative, motile, aerobic bacterium, designated strain h 14(t), was isolated from seawater collected at st kilda beach in port phillip bay, melbourne, australia. analysis of 16s rrna gene sequences revealed that the organism belonged to the roseobacter lineage of the class alphaproteobacteria, forming a distinct evolutionary lineage at the genus level. strain h 14(t) was distantly related to the genera nautella, ruegeria and pseudoruegeria (family rhodobacteraceae). strain h 14(t) ... | 2010 | 19717584 |
| Genomes and Virulence Factors of Novel Bacterial Pathogens Causing Bleaching Disease in the Marine Red Alga Delisea pulchra. | Nautella sp. R11, a member of the marine Roseobacter clade, causes a bleaching disease in the temperate-marine red macroalga, Delisea pulchra. To begin to elucidate the molecular mechanisms underpinning the ability of Nautella sp. R11 to colonize, invade and induce bleaching of D. pulchra, we sequenced and analyzed its genome. The genome encodes several factors such as adhesion mechanisms, systems for the transport of algal metabolites, enzymes that confer resistance to oxidative stress, cytolys ... | 2011 | 22162749 |
