2results about How to "Stable degradation" patented technology

This invention relates to the field of microbial technology, disclosing a *Strombus adhesiveus* strain YF2 that degrades polyethylene mulch film, microbial preparations, methods, and applications, addressing the problems of insufficient efficacy and unclear mechanisms in existing PE-degrading strains. This strain is deposited at the Guangdong Provincial Microbial Culture Collection Center, with accession number GDMCC No:67086, and a deposit date of October 13, 2025. Through systematic parallel comparisons, strain YF2 significantly outperformed the control strain in PE degradation efficiency, biofilm formation ability, and induction of PE polymer oxidation. Genomic analysis showed that YF2 contains a genetic network encoding key degrading enzyme systems such as nitroreductase, cytochrome P450, and alkane monooxygenase, and particularly possesses unique nitrification degradation potential. Microbial preparations prepared based on this strain can be used for the bioremediation of PE mulch film residues in farmland soils, compost, and other environments.

The application discloses a piezoelectric fuel cell and application thereof. The electrode of the application comprises a conductive substrate and a catalytic film fixed on the conductive substrate material, and the catalytic film comprises granular tetragonal phase BaTiO3, has good piezoelectric performance, strong active material loading firmness, simple preparation, low cost and other advantages, and can fully utilize mechanical energy and organic wastewater in the environment when used in the fuel cell, so that stable power generation and degradation of organic pollutants are simultaneously realized. Meanwhile, the tetragonal phase BaTiO3 of the catalytic film on the electrode of the application can improve the conductive performance and piezoelectric performance of the electrode by loading SnO2 or doped SnO2, and the electrode loaded with SnO2 or doped with SnO2 also has good piezoelectric performance, strong active material loading firmness, and simultaneously realizes stable power generation and effective degradation of organic pollutants, and is suitable for the fields of environmental protection and energy.
