Stable glycerol stocks of the pIbpA-antiPBAD and pIbpA-antiHtdR in BW25113 cells with either a pBLN200 or pHtdR200 plasmid were created. Then after inducing the cells with L-arabinose and 10mM all-trans retinal to allow for membrane protein expression, spectrophotometry was used to test the optical density of the cells at an absorbance of 600nm. Although general trends showed that the pHtdR200-pMM102 and pHtdR200-pIbpA cells had lower optical densities than the pBLN200 cells of all types, the results were determined to be statistically insignificant. Continuing, the pHtdR200 cells of all types showed a purple phenotype when spun down, as expected, while the cells with the pBLN200 plasmid had a colorless phenotype in pellet form. Further work will include cloning a GFP gene-block to test the ability of the anti-PBAD sequence in tuning the transcription of the GFP protein.
Temperature swing adsorption is a commonly used gas separation technique, and is being<br/>further researched as a method of carbon capture. Carbon capture is becoming increasingly<br/>important as a potential way to slow global warming. In this study, algae-derived activated<br/>carbon adsorbents were analyzed for their carbon dioxide adsorption effectiveness.<br/>Algae-derived carbon adsorbents were synthesized and then studied for their adsorption<br/>isotherms and adsorption breakthrough behavior. From the generated isotherm plots, it was<br/>determined that the carbonization temperature was not high enough and that more batches of<br/>adsorbent would have to be made to more accurately analyze the adsorptive potential of the<br/>algae-derived carbon adsorbent.
