Influence of mesoporous iron based nanoparticles on Chlorella sorokiniana metabolism during photosynthetic biogas upgrading

• Mesoporous nanoparticles enhanced C. sorokiniana activity during biogas upgrading. CO 2 was adsorbed to the mesoporous surface of nanoparticles. CALPECH boosted productivity and carbohydrate content. UV exposure influenced differently depending on iron source. Three different based (NPs) were added Chlorella batch cultures devoted photosynthetic upgrading enhance biofixation: Fe O 3 , carbon coated zero valent NPs containing 7.26 % (wt%) (CALPECH NPs) 31.38 (SMALLOPS NPS). The three types adsorption therefore in tests conducted 1.2 L enclosed photobioreactors. However, addition 70 mg ?1 resulted a 2-fold enhancement microalgae productivity, lipid content increase by 56 25 %, respectively compared control assay. Under visible light irradiation 5.3-times fold when added. Similarly, 20 SMALLOPS increased 11 under irradiation. Interestingly, did not significantly influence composition suggesting that these particular can act as scavengers. Therefore, could improve fixation
