This invention belongs to the field of microbial technology, and discloses a highly efficient anaerobic fungal strain for degrading lignocellulose in the rumen of Dulong cattle, its cultivation method, and its applications. The strain is *Neisseria gonorrhoeae*. Joblinomyces apicalis DLM2, deposited at the China Center for Type Culture Collection (CCTCC) under accession number CCTCC NO: M 20252927, was isolated from the rumen of Dulong cattle and can be stably cultured under strictly anaerobic conditions. This strain possesses a single-centered cell line and filamentous rhizoids, enabling it to efficiently degrade lignocellulose through a synergistic effect of physical colonization and enzymatic degradation. It exhibits broad adaptability to natural straws such as rice straw and bamboo branches, as well as purified substrates such as microcrystalline cellulose and cellobiose. Its enzyme production exhibits substrate-inducible properties, and fermentation produces various metabolites including formic acid, acetic acid, and ethanol, demonstrating high lignocellulose degradation efficiency. This invention relates to an inoculum containing this strain and its application in lignocellulose degradation, roughage fermentation, agricultural straw resource utilization, and biomass conversion, providing new strain resources and technical support for the efficient degradation and resource utilization of lignocellulose.

This invention provides a numerical simulation method for simulating the effect of moss on concrete strength, belonging to the field of numerical simulation technology for concrete strength. The method includes: obtaining the damage relationship D of the concrete structure to be simulated under the influence of moss; establishing a model WR corresponding to the concrete structure to be simulated; inputting the material parameters of the concrete structure to be simulated and the concrete damage relationship of the internal core area and the external non-core area into WR for numerical simulation; calculating and analyzing the damage factor parameters of the concrete in each area according to D, setting the area with damage factor parameters greater than or equal to a preset damage factor parameter threshold as the moss growth area, and shifting the positions of the rhizoid development area and the corrosion influence area downward; determining the area where the concrete structure to be simulated will fail under the design maximum service life; the method of this invention can accurately simulate the numerical effect of moss on concrete strength.

The application discloses a kind of integrated kelp seedling ropes with self-anchoring structure, belong to seawater culture equipment technical field.The seedling rope includes rope core and the functional outer layer covered outside the rope core;Functional outer layer is made of fiber material, and integrally formed with multiple discrete, recessed towards the rope core direction anchoring hole on it;Anchoring hole has the asymmetric mechanical structure of small mouth and big belly, can produce physical self-locking effect to the kelp seedling rhizoids entering it;At least a part of anchoring hole inside and / or the fiber between its constituting cavity wall, fixed with slow-release nutrient body containing seaweed nutrient element;Slow-release nutrient body is preferentially fixed at the fiber intersection, crevice at anchoring hole cavity bottom and / or wall surface, under the water flow shielding effect of anchoring hole, form local nutrient enrichment microzone inside the cavity, to realize physical anchoring, chemical nutrition induction and reinforced biological interlocking synergistically.The application improves the attachment rate and anti-shedding ability of kelp seedling from the root, has the great potential to realize free division seedling integrated culture.

The invention discloses a gulfweed seedling transplantation and proliferation method and device, and belongs to the technical field of aquatic macroalgae proliferation and culture. The device comprises a flat plate type concrete base, anchoring piles, transplanting auxiliary rods, ribbons and gauze strips, anchoring pile holes and transplanting auxiliary rod holes are formed in the flat plate type concrete base, the anchoring piles are inserted into the anchoring pile holes, and the transplanting auxiliary rods are inserted into the transplanting auxiliary rod holes; the method comprises the following steps: assembling the device, winding the stem of the sargassum offspring seed by using a gauze strip, closing the stem of the offspring seed and the transplanting auxiliary rod, binding by using a binding belt to attach the rhizoid to the base, putting the device to a target sea area, and correcting the position of the device by a diver. The device is convenient to transport and suitable for shallow sea areas, the transplanting survival rate of the gulfweed seedlings can be increased, and the construction cost of a gulfweed field is reduced.
