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.

Microorganisms of the genus Hyphomicrobium and process for degrading

The present invention relates to novel facultative methylotrophic microorganisms of the genus Pseudomonas, or of a genus Pseudomonas-type genus, to protein-containing biomass, and to a process for the microbiological purification of aqueous solutions, e.g. wastewater solutions, which contain methanol, ethanol, acetate, glucose, alkylammonium compounds, e.g., trimethylethylammonium chloride, or alkylamine oxides, e.g. trimethylamine oxide, as pollutants.
