The invention relates to a cell-lysing strain, a sludge reduction microbial inoculant and application thereof, the cell-lysing strain is Geobacillus sp. THE-14, the preservation number of the cell-lysing strain is CCTCC M 2021514, the cell-lysing strain is separated and screened from sludge which is domesticated and mature at high temperature, and the cell-lysing strain and the microbial inoculant containing the cell-lysing strain can be applied to reduction treatment of the sludge. The separated and screened cell-lysing strain is Geobacillus sp. THE-14 which can grow and breed by utilizing organic matters in the sludge, and an enzyme generated in the metabolic process of the strain can accelerate the hydrolysis of extracellular polymeric substances, so that the purpose of sludge lysing is achieved. 本发明涉及一种溶胞菌株、污泥减量用菌剂及其应用，所述溶胞菌株为土芽孢杆菌（Geobacillus sp.）THE-14，保藏编号为CCTCC M 2021514，从高温驯化成熟的污泥中分离筛选得到，所述溶胞菌株和包含所述溶胞菌株的菌剂能够应用于污泥的减量处理中，本发明分离筛选出的溶胞菌株为土芽孢杆菌（Geobacillus sp.）THE-14能够利用污泥中的有机质生长繁殖，菌株代谢过程中产生的酶能够加速胞外聚合物的水解，
