The invention provides a lactobacillus pentosus and a preparation method and application of bacteriocin of the lactobacillus pentosus. The name of the strain is lactobacillus pentosus YCL31, and the strain is preserved in Guangdong Microbial Culture Collection Center (GDMCC) on June 25, 2025, the preservation address is the 5th floor of the building 59, No. 100 courtyard, Xianlie Middle Road, Guangzhou, and the preservation number is GDMCC No: 66589. The bacteriocin separated and purified from the metabolite of the bacterium can destroy the morphological structure of the vibrio parahemolyticus and inhibit the toxicity of the vibrio parahemolyticus, can also achieve the effect of remarkably inactivating the vibrio parahemolyticus in a metapenaeus ensis system, can effectively delay the spoilage of the metapenaeus ensis, and has a good application prospect as a bacteriostatic agent or preservative. Therefore, development and application of the novel bacteriocin have important reference value in related fields.

The present application relates to the technical field of enclosure shrimp culture, in particular to a waste cleaning device for enclosure shrimp fry culture, which comprises: a mounting base, a filter cylinder rotating around the mounting base is arranged on the outer side of the mounting base, a fixed cylinder is fixedly arranged in the middle of the filter cylinder; a water suction pipe and a drain pipe are respectively arranged in the upper half and the lower half of the filter cylinder, and the water suction pipe and the drain pipe are respectively communicated with two compartments in the filter cylinder; a drain port is arranged on the surface of the drain pipe; the beneficial effects are as follows: the mounting base is fixed at the bottom of the culture pond, the filter cylinder rotating around the mounting base is arranged on the outer side of the mounting base, the drain port is arranged on the surface of the drain pipe, the water pump performs water suction through the water suction pipe, the water flow is discharged downwardly through the inclined drain port to impact the bottom of the pond, the reaction force generated by the water flow on the drain pipe pushes the drain pipe and the water suction pipe to rotate as a whole around the mounting base, so that the cleaning area can be automatically changed, manual on-site intervention is not needed, and the device is more convenient and labor-saving to use.
