Proteomic and biochemical responses to different concentrations of CO 2 suggest the existence of multiple carbon metabolism strategies in Phaeodactylum tricornutum.

limitation, while P. tricornutum responds to the HC environment by improving photosynthesis and central carbon metabolism activity. These findings can not only provide evidences for revealing the global picture of biophysical and biochemical CCM in P. tricornutum, but also provide target genes for further microalgal strain modification to improve carbon fixation and biomass yield in algal-based industry.
