  • Patent number: 7118906
    Abstract: The present invention particularly relates to a process of removal of polycyclic aromatic hydrocarbons phenanthrene and chrysene from wastewater and other contaminated sites by using a white-rot fungus Flavodon flavus (K 1) Ryv., which has been deposited at Agricultural Research Service Culture Collection (NRRL), 1815 North University Street, Peoria, Ill. 61604, USA bearing accession number NRRL 30302 on Mar. 10, 2000.
    Type: Grant
    Filed: April 18, 2002
    Date of Patent: October 10, 2006
    Assignee: Council of Scientific & Industrial Research
    Inventors: Chandralata Raghukumar, Mysore Srinivasa-Murthy Shailaja, Shilpa Kamat
  • Patent number: 6953685
    Abstract: The present invention relates to a novel white rot lignin-modifying fungus Flavodon flavus deposited at National Institute of Oceanography, Goa, India, at accession No. 312 which is being deposited in ATCC with accession No. ______, and a process for removal of dyes in dye-containing waste-waters and soil, said process comprising the steps of growing the white rot fungus Flavodon flavus in a nutrient medium containing assimilable carbon and nitrogen source, having optimal salinity up to 15 parts per thousand for a period of about 4-10 days, contacting biomass with effluents containing dyes for a period of at least 5 days followed by separation of the fungal biomass from the effluents by conventional methods to render the effluents substantially free of dyes.
    Type: Grant

    Date of Patent: October 11, 2005
    Assignee: Council of Scientific and Industrial Research
    Inventors: Chandralata Raghukumar, Trevor M. D'Souza, R. Greg Thorn, C. A. Reddy
  • Publication number: 20050101002
    Abstract: Present invention particularly relates to production of alkaline protease for various industries and especially for “enzyme detergents” by a fungus Aspergillus sp. deposited in the microbial type culture collection of Institute of Microbial Technology, Chandigarh, India, under the accession number MTCC 5102 and the said fungus can be grown in conventional media with commercial brands of milk powder using distilled water at pH 7.0 at room temperature (28° C.±2° C.), however, the said fungus grows well in seawater media too and also at 5° C.; further, the protease enzyme produced by this fungus acts equally well in the pH range of 6 to 11 and shows 100% activity at temperature of 42-47° C. but almost 90% of the activity is present at 30° C., 50% of the activity at 15° C. and at 60° C. The enzyme is thermostable up to 45 min at 45° C.
