Flavodon flavus (Klotzsch) Ryvarden

 

Flavodon flavus is a common wood rot mushroom growing adpressed to the substratum. The specimen was collected from Jawhar in Palghar district.

 

Morphology:

 

Fruit body effused reflexed, leathery, up to 2 mm thick, surface of the margin light brown to yellow. Hymenophore initially poroid, becoming with irregular teeth, yellow to pale yellow. Tissue turning reddish brown in KOH. Stipe absent.

Industrial importance:

 

  1. 1.Flavodon flavus is reported for the first time with three major classes of lignin modifying enzymes. A species showed effective degradation of various dye pollutants, thus, it has a potential for bioremediation of aromatic pollutants under marine conditions[1].
  2. 2.Flavodon flavus isolated from a marine habitat was found to be effective in decolorization of brown colored melanoidin pigments present in the wastewaters of molasses-based alcohol distilleries. Further modification in the process made the fungus more effective. Besides decolorization, the fungus also removed the toxicity of molasses spent wash[2].
  3. 3.Flavodon Flavus is used in dyeing industry for its yellow pigment[3].

Review of patents:

 

  1. 1.Pure culture of F. flavus was used for simultaneous decolorization and detoxification of molasses spent wash or water/soil contaminated with molasses spent wash[4].
  2. 2.The process for removal of dyes from dye-containing waste-waters and soil is invented. Flavodon flavus is grown on a medium containing assimilable carbon and nitrogen source. The fungal biomass is then contacted with effluents containing dyes for at least five days followed by separation of the fungal biomass from effluents to make the effluents substantially free of dyes[5].
  3. 3.A process of removal of polycyclic aromatic hydrocarbons phenanthrene and chrysene from wastewater and other contaminated sites by using F. flavus is established[6].

 

Review of publications:

 

  1. 1.The study was conducted on fungus-insect symbiosis. The symbiosis of the insects from genus Ambrosidomus-Flavodon found to be unique in several aspects. It is the first reported association between an ambrosia beetle and a basidiomycotan fungus[7].
  2. 2.The study evaluated the antioxidant potential of F. flavus which generate an important source of natural antioxidant compounds[8].
  3. 3.Flavodonfuran with tremulinolide A were isolated from mangrove derived F. flavus. Tremulinolide shows mild antibacterial and antifungal activities against Staphylococcus aureus and Cryptococcus neoformans respectively[9].
