The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area. [PDF]

Environ Microbiol Rep
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

Studies on the Autoinhibitor Produced by Skeletonema costatum-II. Isolation and Identification of an Autoinhibitor Produced by Skeletonema costatum.

NIPPON SUISAN GAKKAISHI, 1992
An autoinhibitor produced by Skeletonema costatum was extracted with ethyl acetate from the cultured medium. The extract dissolved in diluted aqueous NaOH was gel-filtered on Sephadex G-15 with water. The fractions which inhibited the growth of S. costatum were extracted with ethyl acetate, and the extracts were separated by preparative thin-layer ...
