Franz Heinzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Microorganisms of the genus Hyphomicrobium and process for degrading compounds wich contain methyl groups in aqueous solutions
    Patent number: 4492756
    Abstract: The present invention relates to novel facultative methylotrophic microorganisms of the genus Hyphomicrobium, to protein-containing biomass, and to a process for the microbiological purification of aqueous solutions, e.g. wastewaters, which contain methanol, ethanol, glucose, dimethyl phosphite, trimethyl phosphite, sodium formate, sodium acetate, methylammonium chloride, dimethylammonium chloride, ethylmethylammonium chloride or, chiefly, sodium methyl sulfate, as pollutants. The respective microorganism is cultured in aqueous solution and the pollutant is degraded simultaneously.
    Type: Grant
