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.
Claims17
A process for removal of three-ringed and/or four-ringed polycyclic aromatic hydrocarbons from sites contaminated therewith using white-rot lignin modifying fungus strain Flavodon flavus NRRL 30302, said process comprising:
- (a) growing the white rot strain Flavodon flavus NRRL 30302 in a nutrient medium containing assimilable carbon and nitrogen source for at least 7 days;
- (b) contacting, for at least 3 days, the sites contaminated by the three-ringed and/or four-ringed polycyclic aromatic hydrocarbons with a fungal bio-mass of the Flavodon flavus grown in step (a) under oxygenated conditions with salinity ranging between 0 to 15 parts per thousand, and
- (c) removing said fungal bio-mass to get the contaminated sites devoid of three-ringed and/or four-ringed polycyclic aromatic hydrocarbons.
A process for removal of three-ringed and/or four-ringed polycyclic aromatic hydrocarbons from sites contaminated therewith using white-rot lignin modifying fungus strain Flavodon flavus NRRL 30302, said process comprising:
- (a) growing the white rot strain Flavodon flavus NRRL 30302 in a nutrient medium containing assimilable carbon and nitrogen source for at least 7 days;
- (b) contacting, for at least 3 days, the sites contaminated by the three-ringed and/or four-ringed polycyclic aromatic hydrocarbons with culture filtrate from the Flavodon flavus grown in step (a) under oxygenated conditions with salinity ranging between 0 to 15 parts per thousand, and
- (c) removing said culture filtrate to get the contaminated sites devoid of three-ringed and/or four-ringed polycyclic aromatic hydrocarbons.
