The invention discloses bacillus velezensis Wsy-10 and application of the bacillus velezensis Wsy-10 in improving the wet tensile strength of a plant fiber material, and belongs to the technical field of microorganisms. The invention discloses a bacillus velezensis strain Wsy-10, and the preservation number of the bacillus velezensis strain Wsy-10 is CCTCC (China Center for Type Culture Collection) NO: M 20231661. According to the method, the bacillus velezensis Wsy-10 is used as an original strain for improving the wet strength, rapid sheet making of fiber thick pulp can be achieved, the preparation time of a plant fiber material is shortened, meanwhile, retention of filler can be improved, a chemical flocculant can be replaced, and resource waste and environmental pollution are reduced. 本发明公开了一株贝莱斯芽孢杆菌Wsy-10及其在提高植物纤维材料湿抗张强度中的应用，属于微生物技术领域。本发明公开的一株贝莱斯芽孢杆菌Wsy-10，其保藏编号为CCTCC NO：M 20231661。本发明利用贝莱斯芽孢杆菌Wsy-10作为提高湿强的出发菌株，不仅可实现纤维浓浆的快速抄片，缩短植物纤维材料制备的时间，同时可提高填料的留存，可替代化学絮凝剂，减少资源浪费和环境污染。
