摘要： The growth of algae, fungi and pathogenic organisms in commercial and recreational waters, such as cooling towers, swimming pools and spas, may be controlled by adding to the water a primary sanitizing agent, preferably poly(hexamethylene biguanide) ("PHMB"), and a potentiating adjuvant comprising a calcium ion-chelating agent, preferably ethylenediamine tetraacetic acid ("EDTA"), in amounts such that the adjuvant renders the composition algicidal and fungicidal in water. The water may be further treated with a peroxy salt as a backup agent, preferably sodium perborate, or the calcium ion-chelating agent and peroxy salt may be combined as a shock treatment to water being treated with the primary sanitizing agent.

摘要： The present invention provides an economical and efficient method for the elimination and biodegradation of soil and groundwater containing polar organic solvents, especially acetone. The bioremediation methods of the present invention comprise contacting the bacteria Xanthomonas maltophilia or Bacillus thuringiensis with the contaminated medium under appropriate conditions. In addition, the present invention provides for a composition of matter useful in the bioremediation of a medium, e.g., groundwater or soil contaminated with polar organic compounds, such as acetone.
