Abstract: A rotation connection mechanism includes a first plate, a second plate, a control structure, and a torsion structure. The control structure is configured to control the first plate and the second plate to switch between a first relative position and a second relative position. The first plate and the second plate are at the first relative position, and the first plate and the second plate form a plate. The first plate and the second plate are at the second relative position, and the first plate faces the second plate to have a target angle. The torsion structure is configured to provide torsion support at the first relative position and the second relative position, and provide a force for the control structure to control the first plate and the second plate to switch between the first relative position and the second relative position under an external force.

Abstract: A Bacillus amyloliquefaciens strain MHDS-1 and use thereof in processing of Taxus media are provided, belonging to the technical field of microorganisms. The Bacillus amyloliquefaciens strain MHDS-1 herein is deposited in the China Center for Type Culture Collection (CCTCC) with a deposit number of CCTCC NO: M20231262. The strain is used to process the Taxus media, and can effectively increase a paclitaxel content of the Taxus media, which is not less than 20% higher than that of unprocessed Taxus media.

Abstract: A rotation connection mechanism includes a plate assembly, a movement structure assembly, and a torsion structure assembly. The plate assembly includes a middle plate, a first plate, and a second plate. The first plate is rotatably connected to the middle plate. The second plate is rotatably connected to the middle plate. The movement structure assembly includes a first movement structure and a second movement structure. The first movement structure is arranged at a first end of the plate assembly. The second movement structure is arranged symmetrically with the first movement structure and arranged at a second end of the plate assembly. The torsion structure assembly is arranged on a side of the middle plate and includes a first torsion structure and a second torsion structure. The first torsion structure cooperates with the first movement structure. The second torsion structure cooperates with the second movement structure.
