Renewal of nanofibers in Chlorella fusca microalgae cultivation to increase CO fixation.

This study explored strategies to increase the CO fixation ability of microalgae by renewing polymeric nanofibers in cultures of Chlorella fusca LEB 111. Nanofibers composed of 10% (w v) polyacrylonitrile (PAN)/dimethylformamide (DMF) containing 4% (w v) iron oxide nanoparticles (NPsFeO) were added to photobioreactors. The nanomaterial was renewed in the test cultures as follows: renewal only on day 7; renewal only on day 15; or renewal on both days 7 and 15 (i.
