The objective of this study was to cultivate Chlorella fusca LEB 111 with nanofibers indoors and outdoors to verify the effect on CO2 biofixation and macromolecule production. The microalgae were cultured with 10% (w v-1) polyacrylonitrile (PAN)/dimethylformamide (DMF) nanofibers containing 4% (w v-1) iron oxide nanoparticles (NPsFe2O3), which were added to the cultivations at concentrations of 0, 0.1, 0.3 and 0.5 g L-1. The CO2 biofixation was higher in outdoor assays (270.6 and 310.9 mg L-1 d-1) than in indoor assays (124.6 and 131 mg L-1 d-1) with 0.1 and 0.3 g L-1 nanofibers, respectively. The outdoor assays with 0.3 g L-1 nanofibers had 10.9% greater lipid production than the assays without nanofibers. Thus, this first study of outdoor cultivations with nanofibers as physical adsorbents of CO2 showed the effect of nanostructures in maximizing gas biofixation and producing biomolecules that can be used to obtain bioproducts.
