Abstract

A method for killing or inactivating spores, by contacting the spores with a haloperoxidase, a source of hydrogen peroxide and a source of iodide ions. The spores may additionally be contaced with a haloperoxidase enhancing agent.

Claims

exact text as granted — not AI-modified
1 - 14 . (canceled)  
   
   
       15 . An enzymatic method for killing or inactivating spores, which comprises contacting the spores with a haloperoxidase, a source of hydrogen peroxide and a source of iodide ions.  
   
   
       16 . The method of  claim 15 , wherein the haloperoxidase is a bromoperoxidase or a chloroperoxidase.  
   
   
       17 . The method of  claim 15 , wherein the haloperoxidase is a vanadium containing haloperoxidase.  
   
   
       18 . The method of  claim 15 , wherein the source of iodide ions is a salt of iodide.  
   
   
       19 . The method of  claim 15 , which further comprises contacting the spores with an enhancing agent.  
   
   
       20 . The method of  claim 15 , which further comprises contacting the spores with a surfactant.  
   
   
       21 . The method of  claim 15 , wherein the spores are located on a surface.  
   
   
       22 . The method of  claim 21 , wherein the surface is a textile surface.  
   
   
       23 . The method of  claim 21 , wherein the surface is a surface of laboratory or process equipment.  
   
   
       24 . A method of decontaminating a location exposed to spores, which comprises contacting the spores with a haloperoxidase, a source of hydrogen peroxide, a source of iodide ions and an enhancing agent.  
   
   
       25 . The method of  claim 24 , wherein the source of iodide ions is one or more salts of iodide.  
   
   
       26 . The method of  claim 24 , which further comprises contacting the spores with a surfactant.  
   
   
       27 . A container comprising a haloperoxidase, a source of hydrogen peroxide and a source of iodide ions, wherein the haloperoxidase, the source of hydrogen peroxide and the source of iodide ions are packaged in one or more compartments or layers.
