  • Patent number: 12103878
    Abstract: A biofilm composite carrier and a preparation method and use thereof are provided. The biofilm composite carrier includes a polyurethane framework, an adhesive and a functional material, wherein the functional material is adhered to the surface and pores of the polyurethane framework through the adhesive, and the functional material is a mixture of zeolite and tourmaline. The biofilm composite carrier is beneficial to the quick start-up and stable operation of the municipal sewage deammonification system under conditions of low temperature and low ammonium.

  • Patent number: 12043825
    Abstract: The present disclosure relates to the technical field of culture materials for fungi and provides a solid medium for Coriolus versicolor, and a preparation method and use. Bran is used as a main component in the solid medium, and has advantages in economy and environmental protection, and provides high Coriolus versicolor growth rate and strong contamination resistance. The solid medium avoids the tendency to contamination of current media during an experimental process, and reduces culture cost. The solid medium provides higher biomass and stronger contamination resistance than a potato dextrose agar (PDA) medium.

  • Publication number: 20240002829
    Abstract: The present disclosure provides an immobilized crude enzyme for degrading complex polycyclic aromatic hydrocarbons (PAHs) in soil and a preparation method thereof, and relates to the field of remediation of complex organics-polluted soil. The present disclosure particularly relates to an immobilized crude enzyme and a preparation method thereof. In the present disclosure, the immobilized crude enzyme for degrading complex PAHs in soil is prepared from an acid-modified chestnut inner shell and a crude enzyme solution of white rot fungi; and there are copper ions in the crude enzyme solution of the white rot fungi. The preparation method includes: 1, preparing a chestnut inner shell into a powdered material; 2, preparing modified biochar; 3, conducting immobilization.
