Study IDST002957
Study TitleMetabolite flux from temperature-acclimated diatom strains (main experiment)
Study SummaryThe temperature increase occurring in the surface ocean has fundamental implications for physiological rates and processes of marine microbes. Here we asked whether the temperature at which a marine diatom strain is acclimated affects carbon transfer to a co-cultured heterotrophic bacterium. Model systems were established in which the diatom Thalassiosira pseudonana was acclimated for three months at temperatures below (14°C), equal to (20°C), and above (28°C) the temperature of optimal growth, and then inoculated with the heterotrophic bacterium Ruegeria pomeroyi. This deposition is for the results of diatom endometabolites obtained from the main experiment of this study.

Collection:

Collection ID:CO003063
Collection Summary:Based on pre-experimental axenic growth curves, harvests occurred at days 3 (28°C), 4 (20°C), and 6 (14°C), starting 7 h into the light cycle. At each harvest, subsamples of 600 mL were filtered onto 2.0-µm Isopore filters (Millipore, Burlington, MA) for diatom endometabolite analysis and stored in 50-mL centrifuge tubes at -80°C.

Sample Type:Algae
Storage Conditions:-80℃

Treatment:

Treatment ID:TR003079
Treatment Summary:Six treatment combinations of a marine diatom strain Thalassiosira pseudonana CCMP1335 were prepared: treatments incubated axenically at either 14, 20, or 28 oC, and treatments co-cultured with a bacterial strain Ruegeria pomeroyi DSS-3 at the corresponding temperatures (four replicates for each). L1 media was used with NaH13CO3 as a source of bicarbonate and a salinity of 35 ppt. The diatom used for the co-cultured treatments was B12 stressed to emphasize the known co-existing system. The light cycle consisted of 16 h light (120 µmol photons m-2 s-1) and 8 h of dark.

Sample Preparation:

Sampleprep ID:SP003076
Sampleprep Summary:Filter samples were transferred into 15-mL of ultrapure MilliQ water in 50-mL tubes, and diatom cells were removed from the filters by sonication in an ice-water bath for 7 min (cycle: 50 s on and 10 s off). The liquid fraction was subsequently collected in new tubes and the procedure repeated three times, after which fractions were combined and stored at -80°C until further processing. Samples were lyophilized (Labconco, Kansas City, MO, USA) and pellets mixed with 600 μL of phosphate buffer (30 mmol L-1 phosphate in deuterated water, pH 7.4) and 1 mmol L-1 internal standard 2,2-dimethyl-2-silapentane-5-sulfonate (DSS). Samples were vortexed for 5 min, centrifuged at 20,800 relative centrifugal force (RCF) for 10 min, and supernatants were transferred to 5-mm NMR tubes (Bruker, Billerica, MA, USA). Extraction and buffer blank controls were also prepared. Additionally, one pooled control sample was prepared by combining aliquots of all the samples and used for annotation.
