Miller2 1Baltimore City Community College, Life Science Institute, 801 West Baltimore Street, Baltimore, MD 21201 2Department of Biological Sciences, UMBC, 1000 Hilltop Circle, Baltimore, MD 21250 Algae hold great promises for production of liquid fuels but current yields are not high enough to compete with fossil fuels. Therefore there is a need to engineer algae to accumulate more biomass more quickly. Chlamydomonas reinhardtii is the E. coli of algae—many molecular genetic tools have been developed to manipulate it and its genome is sequenced and well characterized. In this study we are focusing on the Calvin cycle, a photosynthetic pathway localized to the stroma of the chloroplast that fixes carbon dioxide and produces sugar. The enzyme fructose bis-phosphate aldolase (FBA) is believed to carry out a key control step in the Calvin cycle. FBA combines glyceraldehyde-3- phosphate and dihydroxy acetone phosphate to form fructose-1,6-bisphosphate, a precursor to the 5-carbon sugar ribulose bisphosphate (RuBP) that must be regenerated in each round of the Calvin cycle. The main aim of our study is to determine whether we can increase the growth rate of C. reinhardtii by increasing the expression of FBA. To that end we have gene synthesized the coding sequence for C. reinhardtii FBA using C. reinhardtii chloroplast codon bias and are subcloning this sequence into our chloroplast transformation vector. Progress toward this goal will be reported. After transforming and selecting for spectinomycin
