The utility model relates to the technical field of infectious microbe killing devices, and discloses a tremella aurantialba bag infectious microbe killing device which comprises a cultivation box, a containing basket and an opening and closing assembly, the opening and closing assembly facilitating roll paper replacement is arranged at the rear end of the cultivation box, and the containing basket is fixedly connected into the cultivation box. After the driving pipe gets close to the roll paper support, the broken end of the roll paper is adsorbed, water is sprayed to the dragged paper through the atomization spray head, after the driving pipe gets close to the sealing door, the driving pipe stops moving, the pulled paper is cut off through the cutter body, and the cut-off paper downwards covers the corresponding containing basket due to the gravity of water humidification. After fungus bags in the containing basket absorb moisture through the soaked broken paper, the paper falls into the containing frame at the rear end of the sealing door, paper laying and paper replacing work can be conveniently conducted on the premise that the incubator is not opened, bacteria, mold spores and the like in the air are prevented from directly entering the incubator, and the tremella aurantialba mildewing risk is reduced.

This invention relates to the field of fermentation technology, and specifically provides a *Aspergillus niger* strain with accession number CCTCC NO: M 20251780. This invention utilizes a selected multi-enzyme *Aspergillus niger* strain for solid-state fermentation to prepare a composite fermentation agent rich in various solid-state fermentation enzymes and mold spores. This agent serves as a functional adjuvant for molasses alcohol yeast fermentation, significantly improving the fermentation performance of the alcohol yeast. It substantially increases the fermentation speed and alcohol content of molasses alcohol, achieving an alcohol yield of 93.23%, effectively solving the problems of unstable fermentation performance and low alcohol yield in molasses alcohol yeast.

This invention relates to the field of archival storage protection technology, providing an RFID anti-interference reading and writing device for a closed environment based on adaptive frequency hopping. The device includes an intelligent cabinet with multiple spaced-apart partitions dividing the cabinet into several independent storage areas. Each partition includes a hollow partition, a hollow tube, a pressure plate, and two sealing plates slidably mounted on top of the hollow partition. The device also includes an air supply mechanism connected to the hollow interior of the partitions. When an archive is placed between two adjacent partitions, the pressure plates on both sides of the archive are pressed together. The pressure plates, through the hollow tube, drive the two sealing plates to slide back-to-back along the top of the hollow partition, releasing airflow nozzles of corresponding area according to the actual thickness of the archive. Dry airflow supplied by the air supply mechanism is ejected from the nozzles, forming an air wall between the archives. This invention separates adjacent archives through the air wall, dispersing accumulated moisture between archives, preventing cross-spread of mold spores, and improving the local airflow organization of the archive storage environment.

An infection control filter label includes a frame and a filter membrane that covers a window through the frame. The frame may be removably secured to a cover for an item, such as a cushion (e.g., a pillow, a positioner, a mattress topper, a mattress, a seat cushion, etc.), bedding (e.g., a duvet, etc.), or the like to provide a sealed cover for the item. The sealed cover may be impermeable and / or impervious to infectious agents, with the infection control filter label limiting the passage of dust and microorganisms (e.g., fungi, bacteria, mold spores, etc.) from passing therethrough. Thus, the sealed cover may protect its contents from external factors (e.g., sick individuals, etc.) while protecting the environment outside the sealed cover from the contents of the sealed cover. Information about the item may be provided on the frame; for example, by printing, writing, or the like.

The invention relates to the technical field of fermentation, and provides an Aspergillus niger with the preservation number of CCTCC (China Center for Type Culture Collection) NO: M 20251780. According to the invention, a composite leavening agent rich in a plurality of solid state fermentation biological enzyme systems and mold spores is prepared by carrying out solid state fermentation on a preferred multi-enzyme system aspergillus niger strain, and the composite leavening agent is used as a molasses alcohol yeast fermentation functional auxiliary material, so that the fermentation performance of alcohol yeast is greatly improved. The molasses alcohol fermentation speed and the fermentation alcohol content are remarkably improved, the wine yield reaches 93.23%, and the problems that molasses alcohol yeast is unstable in fermentation performance and low in wine yield are effectively solved.
