气液相等离子体增强微藻固碳与脱氮协同策略
Gas-liquid phase plasma enhanced synergistic strategy for carbon fixation and denitrification in microalgae
Using Chlorella sp.as the research subject,liquid-phase RONS induced by gas-liquid phase plasma was applied for treatment,and the dominant mutant strain LA-F6 with altered genetic information was screened.By comparing its biochemical and photosynthetic performance with that of the wild-type strain,the effect of mutagenesis on Chlorella’s nitrogen removal and carbon fixation efficiency was explored.Results showed that during the cultivation period,LA-F6 achieved a maximum biomass of 3.33 g/L,nitrogen removal efficiency of 5.48%,and carbon fixation efficiency of 0.44 g/(L·d),corresponding to increases of 8.82%,1.84%,and 13.64% over the wild-type strain,respectively.At the same time,LA-F6 exhibited significantly improved photosynthetic performance,lipid content,and pigment production.The synergistic strategy of enhancing microalgal nitrogen removal and carbon fixation performance through gas-liquid phase plasma provides an effective approach and pathway for carbon reduction,pollution treatment,and the co-production of high-value-added products.
