Growth Rate of Phaeodactylum tricornutum.

Genome properties of the diatom Phaeodactylum tricornutum.

Diatoms are a ubiquitous class of microalgae of extreme importance for global primary productivity and for the biogeochemical cycling of minerals such as silica. However, very little is known about diatom cell biology or about their genome structure. For diatom researchers to take advantage of genomics and post-genomics technologies, it is necessary to establish a model diatom species. Phaeodac...

Effect of growth rate and CO, concentration on carbon isotopic fractionation by the marine diatom Phaeodactylum tricornutum

The carbon isotopic composition (813C) of the marine diatom PhaeodactylurY1 tricomutum was measured over a series of growth rates (p) in a chemostat system in which both the Si3C and the concentration of aqueous CO, [CO,(aq)] were measured. CO,(aq) ranged from 0.64 to 35 pmol kg-l and growth rates from 0.5 to 1.4 d-l. eP, the biological fractionation factor associated with carbon fixation, was ...

Dynamics of the bacterial community associated with Phaeodactylum tricornutum cultures

The pennate diatom Phaeodactylum tricornutum is a model organism able to synthesize industrially-relevant molecules. Commercial-scale cultivation currently requires large monocultures, prone to bio-contamination. However, little is known about the identity of the invading organisms. To reduce the complexity of natural systems, we systematically investigated the microbiome of non-axenic P. trico...

Regulation of the Calvin cycle in the diatom Phaeodactylum tricornutum

IV Regulation of the Calvin cycle in the diatom Phaeodactylum tricornutum Phaeodactylum tricornutum is an important model organism for diatoms, one of the prevalent phytoplankton on earth. Diatoms are unicellular, eukaryotic and photoautotrophic microalgae, which contribute greatly to the global carbon cycle efficiently transforming CO2 into carbon compounds via the Calvin cycle pathway. There ...
