The invention discloses a preparation method and application of a biomass carbon nanofiber membrane loaded with microorganisms. In the liquid culture medium, after culturing to the logarithmic growth phase at 27-29 °C, the culture was incubated for 9-11 h, so that the arsenic-oxidizing Heshanmonas in the culture solution was fully adhered to the biomass carbon nanofiber membrane, That is, the microorganism-loaded biomass carbon nanofiber membrane is obtained. The microorganism-loaded biomass carbon nanofiber membrane prepared by the present invention shows good As(III) biocatalytic effect and recycling performance in five cyclic reaction cycles, and is a good microorganism carrier, and with As the number of cycles increased, the catalytic efficiency of As(III) oxidation by the microbial composite membrane gradually increased. |
