| Study Title | Deciphering the metabolomic differences between two fast-growing cyanobacteria, S.elongatus PCC 11801 and 11802 via metabolite profiling |
| Study Summary | The study aims to identify the metabolic differences between two promising fast-growing, non-model cyanobacterial strains, S. elongatus PCC 11801 and PCC 11802. To this end, experiments were carried out to measure metabolite levels in the two cyanobacterial strains grown in shake flasks at a similar light intensity of approx. 300-350 µmole photons.m-2. s-1. The samples for metabolomics analysis were collected during the exponential growth phase at an optical cell density of 0.5-0.6. Isotopic ratio method was utilized to compare the metabolite levels and delineate the differences in their metabolic pathways. |

Sample Preparation:
| Sampleprep ID: | SP002337 |
| Sampleprep Summary: | One aliquot of the metabolite extract of each sample were reconstituted in 100µL 50:50 methanol-water and filtered using nylon syringe filters to remove any particulate matter. The metabolite extract of each test sample was mixed with equal volume of an extract of the PCC 11801 WT biomass that is fully labeled with 13C isotopic carbon by growing for ~5 generations in the presence of NaH13CO3 in modified BG-11 medium. 13C-labeled biomass of PCC 11801 that acted as an internal standard. The injection volume was 6 µL. The peak areas corresponding to the 12C and 13C monoisotopic peak for the metabolites of interest were quantified using MultiQuant 3.0.1 (SCIEX, Framingham, MA). The relative quantification of metabolites was done using isotopic ratio method by normalizing area under the peak for monoisotopic m/z of a particular metabolite by its respective highest possible isotopologue present in the internal standard giving area ratio. |
