Our objective is to understand basic biology and metabolic/regulatory pathways in unicellular photosynthetic model microalga Chlamydomonas reinhardtii regarded as non-oleaginous. While under optimal growth conditions, it synthesizes fatty acids principally for esterification into membrane lipids, under conditions limiting to growth, particularly nutrient deprivation, it slows down the cell proliferation and alters the lipid biosynthetic pathways towards the formation and accumulation of the carbohydrates (starch) and neutral lipid triacylglycerols (TAGs). TAGs are one of the most energy-rich forms of reduced carbon available from nature. They can be converted to biodiesel by trans-esterification with methanol in the presence of an acid or alkali catalyst. C. reinhardtii is unlikely to be chosen for biofuel production. However, it is a model alga whose complete genome is available and used as a reference to understand metabolic and regulatory networks involved in lipid metabolism and TAG accumulation. For economic viability and sustainability of algal biofuels, it is essential to understand the basic biology of potential microalgae, particularly the effects of environmental stresses on cellular metabolisms and the regulation of biosynthetic pathways of fatty acids and TAGs, as well as carbon fixation and allocation. Neutral lipid biosynthesis and turnover have been studied in higher eukaryotes particularly yeast, mice, and the model plant Arabidopsis thaliana where extensive knowledge exists on lipid metabolism and several key enzymes identified. However, these pathways are not fully documented in microalgae and little is known about the enzymes involved in the formation, accumulation, or degradation of TAGs. More research is needed to understand signal perception and transduction under stress and different molecular mechanisms leading to TAG and starch accumulations in microalgae. In this context, rapidly developing systems-level “Omics” analyses (transcriptomics, proteomics, metabolomics), which are both sensitive and quantitative, and the availability of annotated genomes allow us to investigate changes in response to environmental stress. This may provide useful hypotheses for microalgal strain improvement to optimize their biofuel production.
Currently, our research project focuses on:
- Identification and characterization of robust microalgae from various collections for the genetic improvements for biofuel production.
- Genome sequencing and annotation of selected microalgae for facilitating pathway engineering.
- Investigating components of lipid biosynthetic pathway and its regulation in microalgae.
- Characterization of quality of lipid in the microalgae and corresponding biosynthetic pathways.
- Engineering microalgae for improving the quality of lipid for biodiesel production.
- Study of genetic mechanism and enzymes responsible for self-flocculation and its exploitation in algae.
Our findings will provide important breakthrough on central metabolism in these microalgae, which are required for biotechnological improvement of next-generation biofuel production.
