  • Degrading sludge with microorganisms ATCC 55926 OR 202050
    Patent number: 6420165
    Abstract: A biologically pure culture of a microorganism is provided designated SH2A and deposited under ATCC Accession No. 55926, or a mutant derived therefrom. Further provided is a biologically pure culture of a microorganism designated SH2B and deposited under ATCC Accession No. 202050, or a mutant derived therefrom. A method of degrading an organic material such as sludge is carried out by treating the organic material with an effective, degrading amount of either SH2A or a mutant derived therefrom, or SH2B or a mutant derived therefrom. The microorganism designated SH2A or a mutant derived therefrom, or SH2B or a mutant derived therefrom, is grown by culturing the microorganism at a temperature and in a medium effective to promote growth of the microorganism.
