Screening method of cell-lysing strain, cell-lysing strain and application of cell-lysing strain

The invention relates to a screening method of a cell lysing strain, the cell lysing strain and application of the cell lysing strain, the cell lysing strain is Geobacillus sp. DX11 and is preserved in the China Center for Type Culture Collection (CCTCC), and the preservation number is CCTCC M 2023509; a flat plate solid culture medium used in the single colony separation process comprises D-calcium pantothenate, nitrilotriacetic acid, NaCl, MgSO47H2O, Na2HPO4H2O, NH4Cl, peptone, a yeast extract, K2HPO4, D-glucose, agar and trace elements. The lysing bacterial strain can grow and breed by utilizing organic matters in sludge, and enzymes generated in the metabolic process of the lysing bacterial strain can accelerate the hydrolysis of extracellular polymeric substances and the lysis of sludge cells, so that the purpose of sludge lysing is achieved, the degradation rate of VSS in the sludge reduction treatment process is greatly improved, and the amount of residual sludge is reduced. 本发明涉及一种溶胞菌株的筛选方法、溶胞菌株及其应用，所
