This study developed a co-culture system of marine diatom ST:STUDY_SUMMARY Thalassiosira pseudonana and heterotrophic bacterium Ruegeria pomeroyi, and ST:STUDY_SUMMARY addressed diel changes in phytoplankton endometabolite production using nuclear ST:STUDY_SUMMARY magnetic resonance (NMR) and bacterial metabolite consumption using gene ST:STUDY_SUMMARY expression. Here we deposit data for NMR analysis from the study. Samples were ST:STUDY_SUMMARY collected every 6 hours over two days under a diel light cycle. During the ST:STUDY_SUMMARY course of the study, we observed an increase in some phytoplankton ST:STUDY_SUMMARY endometabolites presumably due to the effects of the associated bacteria. We ST:STUDY_SUMMARY introduced an additional experiment and tested this possibility by comparing ST:STUDY_SUMMARY phytoplankton endometabolite accumulation between axenic treatments and bacteria ST:STUDY_SUMMARY coculture treatments.

Filters were kept in 50 mL tubes CO:COLLECTION_SUMMARY (Falcon) and stored at -80oC until processing. Test of model prediction CO:COLLECTION_SUMMARY experiment – The same procedure was used except that samples were collected at CO:COLLECTION_SUMMARY day 15 and 700 mL of the culture was filtered.

The light cycle consisted of 16 h TR:TREATMENT_SUMMARY light, during which light intensity varied gradually between 0 and 150 µmol TR:TREATMENT_SUMMARY photon m-2 s-1 with a maximum intensity at noon, followed by 8 h of dark. TR:TREATMENT_SUMMARY Bacterial strain Ruegeria pomeroyi DSS-3 was grown at 30oC on ½ YTSS agar and TR:TREATMENT_SUMMARY transferred to ½ YTSS liquid2 medium for overnight growth. Axenic T. pseudonana TR:TREATMENT_SUMMARY cultures grown for 6 days were inoculated with bacterial cells washed in L1 TR:TREATMENT_SUMMARY medium three times (final concentration, 106 bacterial cells mL-1). Co-cultures TR:TREATMENT_SUMMARY were pre-incubated for two days. Test of model prediction experiment – T. TR:TREATMENT_SUMMARY pseudonana was inoculated into L1 as described above. Triplicate samples were TR:TREATMENT_SUMMARY inoculated with three heterotrophic bacteria (R. pomeroyi DSS-3, TR:TREATMENT_SUMMARY Stenotrophomonas sp. SKA-14, and Polaribacter dokdonensis MED-152). Another set TR:TREATMENT_SUMMARY of triplicate samples was kept axenic (diatom only). The cultures were TR:TREATMENT_SUMMARY maintained under 16 h of light period (160 µmol photons m-2 s-1) and 8 h of TR:TREATMENT_SUMMARY dark period cycles.

For the test of model prediction SP:SAMPLEPREP_SUMMARY experiment, 300 µL of supernatants were further diluted with 250 µL of the SP:SAMPLEPREP_SUMMARY buffer and transferred to NMR tubes. All the sample preparation steps were done SP:SAMPLEPREP_SUMMARY on ice or in a cold room (4oC).
