Study TitleImpact of thiamine metabolites and spent medium from Chlorella sorokiniana on metabolism in the green algae Auxenochlorella prototheciodes (part I)
Study SummaryThe purpose of this study is to determine how thiamine metabolites impact central metabolism in Auxenochlorella protothecoides when grown in the presence of glucose. We hypothesize that thiamine metabolites alleviate bottlenecks in the TCA cycle and gluconeogensis, thus allowing for greater starch production when they are present. Cells were grown in bioreactors: 3 control cultures with no thiamine metabolites, 3 cultures received thiamine, 3 recieved HMP, and 3 were grown on residual medium from another algae species - Chlorella sorokiniana. We suspect that this residual medium also contains thiamine metabolites. Samples were taken daily from each of these 12 cultures over a 5 day time course so that we can observe build-up of metabolites over time.

Collection:

Collection ID:CO001001
Collection Summary:1 ml algae cell culture was collected, 1 ml 70% MeOH (30% dH2O) at -80 C was added to the algae sample. Tubes were spun at 12,000 rcf to pellet for 2 min at 0 C. Supernatant was decanted and pellets stored at -80 before freeze drying at -45 C. Freeze dried samples were stored at -20 C until submission for extraction.

Sample Preparation:

Sampleprep ID:SP001014
Sampleprep Summary:1. Check the pH of methanol (pH 7) 2. Make the extraction solution by mixing methanol, chloroform, and water in proportions of 10 : 3 : 1 3. Rinse the extraction solution for 5 min with nitrogen, making sure that the nitrogen line was flushed out of air before using it for degassing the extraction solvent solution. 4. Add one metal ball to each Eppendorf tube, close, and place in liquid nitrogen. 5. Take the Eppendorf tubes from the liquid nitrogen and place into the tube-holder of the grinder being careful to compensate for weight, maintaining equilibrium. 6. Shake for 30s at a frequency of 25 s-1 and check that the leaves have been ground into a fine powder. Repeat if necessary, submerging in liquid nitrogen first. 7. After grinding add 500μL of pre-chilled extraction solution to each tube one by one to prevent even partial thawing of the sample. Store all samples on ice while finishing this step. 8. Vortex the sample for 20s. 9. Centrifuge for 3min at 14,000 rcf using the centrifuge Eppendorf 5415 D. 10. Remove the whole supernatant into a clean Eppendorf tube. 11. Add 800μL of extraction solvent back into the tube with the pellet and metal ball. 12. Vortex the sample again for 20s. 13. Centrifuge for 3min at 14,000 rcf using the centrifuge Eppendorf 5415 D. 14. Remove the whole supernatant and combine with the previous supernatant. 15. Dry in the Labconco Centrivap cold trap concentrator to complete dryness and submit for derivitization.
