“…An excess of ammonium sulfate (high N-high C) suppressed degradation significantly and 56% of the initially added CL-20 remained in the reaction medium 24 hours after the addition of the nitramine. Assuming that MnP is the major degrading enzyme for CL-20, this result is not surprising according to several studies that report maximum MnP activities under nitrogen-limited conditions, in Phanerochaete chrysosporium cultures [ 34 , 35 ].…”

Abstract:The aerobic biodegradability of the high explosive CL-20 by activated sludge and the white rot fungus Phanerochaete chrysosporium has been investigated. Although activated sludge is not effective in degrading CL-20 directly, it can mineralize the alkaline hydrolysis products. Phanerochaete chrysosporium degrades CL-20 in the presence of supplementary carbon and nitrogen sources. Biodegradation studies were conducted using various nutrient media under diverse conditions. Variables included the CL-20 concentration; levels of carbon (as glycerol) and ammonium sulfate and yeast extract as sources of nitrogen. Cultures that received CL-20 at the time of inoculation transformed CL-20 completely under all nutrient conditions studied. When CL-20 was added to pregrown cultures, degradation was limited. The extent of mineralization was monitored by the 14 CO 2 time evolution; up to 51% mineralization was achieved when the fungus was incubated with [ 14 C]-CL-20. The kinetics of CL-20 biodegradation by Phanerochaete chrysosporium follows the logistic kinetic growth model.

“…The Phanerochaete chrysosporium commonly known as white rot fungi 16 is well known for digestion of fragrant poisons, lignin and lipids and remediation of various pollutants such as PAH, heavy metals and dyes 17 . Phanerochaete chrysosporium is considered an uncommon organism for its capacity to depolymerize and change lignin, cellulose and hemicellulose, in comparison with different basidiomycetes 18 .…”

The Himalayan region is conferred by diverse wealth in term of flora and fauna. Among Himalayan plant biodiversity, Saussurea obvallata (common name Brahma Kamal) has an immense spiritual and medicinal significance. Owing to high demand, this herb is on the verge of extinction. Numerous studies have been carried out for preservation and in vitro regeneration of Saussurea obvallata. In view of above, this is the first study which aims to isolate and identify rhizospheric fungi associated with this plant. Soil samples were collected from three locations in Kedarnath valley and total 34 fungal isolates were isolated. Out of 34, three fungal isolates i.e. MaHaD1, MaHaD2 and MaHaD3 were selected for morphological and molecular characterization. The 16S rDNA sequencing identified MaHaD1, MaHaD2 and MaHaD3 as Phanerochaete chrysosporium, Trichoderma longibrachiatum and Aspergillus fumigatus respectively. The presence of these three dominant fungi in rhizospheric region seems to be results of climatic conditions and plant physiology. Results indicate that the presence of fungal microflora may play a vital role in survival and proliferation of Saussurea obvallata plant by providing tolerance and resistance to abiotic stress and fungal/nematode pathogens respectively.

“…LiP H8 of P. chrysosporium cultures displayed the formation of a number of oxidation products upon incubation of Congo Red at pH 3.0 (Tatarko and Bumpus, 1998). The decolorization of dyes increased with higher LiP concentrations (Wu et al, 1996). The addition of VA enhanced the decolorization of Reactive Red 22 to 96% within 3 minutes.…”
