TI  - Effects of culture parameters on the degradation of 2,4-dichlorophenoxyacetic 
      acid (2,4-D) and 2,4-dichlorophenol (2,4-DCP) by selected fungi. Groupe pour 
      l'Etude du Devenir des Xenobiotiques dans l'Environnement (GEDEXE).

AB  - In order to enhance 2,4-D and 2,4-DCP degradation by four selected fungi 
      (Cunninghamella elegans, C. echinulata, Rhizoctonia solani and Verticillium 
      lecanii), three culture parameters (initial chemical concentration, amounts of 
      glucose and nitrogen) were varied. The levels of both xenobiotics in the culture 
      media were monitored by HPLC analysis after five days of cultivation. The best 
      results were obtained at low initial concentration (20 mg.L-1 vs 100) and with 
      low amounts of glucose (5 g.L-1 vs 10) and nitrogen (2.4 mM vs 24). When these 
      two elements were lacking from the culture media, biodegradation was not 
      suppressed, but took place to a lesser extent. Thus, initial chemical 
      concentration and amounts of carbon and nitrogen, in the culture medium, were 
      shown to strongly influence the extent of 2,4-D and 2,4-DCP removal by fungi.
