The bacterial strain AP-MA-4^(T) isolated from the marine dinoflagellate Alexandrium pacificum (KCTC AG60911), was subjected to a taxonomic analysis. Cells of strain AP-MA-4^(T) were Gram-stain-negative, aerobic, rod-shaped, optimum growth at 20 °C, pH 7.0, in the presence of 5% (w/v) NaCl. Strain AP-MA-4^(T) shared the highest 16S rRNA gene sequence similarity to Pseudosulfitobacter pseudonitzschiae DSM 26824^(T) (98.5%), followed by Ascidiaceihabitans donghaensis RSS1-M3^(T) (96.3%),…

Building consensus around the assessment and interpretation of Symbiodiniaceae diversity
Within microeukaryotes, genetic variation and functional variation sometimes accumulate more quickly than morphological differences. To understand the evolutionary history and ecology of such lineages, it is key to examine diversity at multiple levels of organization. In the dinoflagellate family Symbiodiniaceae, which can form endosymbioses with cnidarians (e.g., corals, octocorals, sea anemones, jellyfish), other marine invertebrates (e.g., sponges, molluscs, flatworms), and protists (e.g.,…

<em>Gymnodinialimonas phycosphaerae</em> sp. nov., a phycosphere bacterium isolated from <em>Karlodinium veneficum</em>
A facultative anaerobic, Gram-negative, non-motile, rod-shaped bacterial strain, designated N5^(T), was obtained from the phycosphere microbiota of the marine planktonic dinoflagellate, Karlodinium veneficum. Strain N5^(T) showed growth on marine agar at 25 °C, pH 7 and 1 % (w/v) NaCl and produced a yellow colour. According to a phylogenetic study based on 16S rRNA gene sequences, strain N5^(T) has a lineage within the genus Gymnodinialimonas. The G+C content in the genome of strain N5^(T) is…
