Collection ID:CO001385
Collection Summary:Marine microalgae Microchloropsis gaditana NIES 2587 is procured from Microbial Culture Collection, National Institute for Environmental Studies (NIES), Tsukuba, Japan. The strain was grown in minimal medium F/2 (Guillard and Ryther, 1962) under a light regime of 16:8 h and an illumination of 150 µmol m−2 s−1 photosynthetically active radiation (PAR) in a multi-cultivator MC 1000-OD (Photon Systems Instruments, Czech Republic) with a flow rate of 800 mL min-1 with continuous bubbling of air at 24 °C.
Sample Type:Algae


Treatment ID:TR001405
Treatment Summary:Microchloropsis gaditana cells were grown in a Multicultivator in the presence of very-low CO2 (300 ppm) and high CO2 (30,000 ppm) for 9 days with an illumination intensity of 150 uE.
Treatment Compound:CO2

Sample Preparation:

Sampleprep ID:SP001398
Sampleprep Summary:Quenched cells were resuspended in 1 mL of ice-cold methanol/ethanol/chloroform(2:6:2), followed by sonication of resuspended cells in sonication bath for 15 min. Later, these samples were centrifuged at 10,000×g for 15 min at 4 °C to get rid of cell debris. The supernatant was filtered using a 0.2-µm filter. One hundred microlitres of supernatant was taken and dried under nitrogen stream. The dried leftover was dissolved in 10 µL of freshly prepared methoxyamine hydrochloride solution (40 mg mL−1 in pyridine) and incubated at 30 °C for 90 min with shaking. To the above solution, 90 µL of N-methyl-N-(trimethylsilyl)trifluoroacetamide was added and incubated at 37 °C for 30 min. The samples were centrifuged at 14,000×g for 3 min, and the supernatant was taken for the GC-MS/MS analysis.

Chromatography ID:CH001606
Chromatography Summary:GC-triple quadrupole analysis was performed on an HP-5 gas chromatograph with standard liners containing glass wool in split mode (1:5) at 250°C injector temperature. The GC was operated at constant flow of 1 ml/min helium on a 30-m, 0.25-mm i.d., 0.25-μm HP-5 column, a start temperature of 60°C, 3 min isothermal, temperature ramping by 5°C/min to 180°C, 3 min isothermal and finally temperature ramping of 10°C/min to 310°C.
