TI  - Fungal bioconversion of 2,4-dichlorophenoxyacetic acid (2,4-D) and 
      2,4-dichlorophenol (2,4-DCP).
PG  - 1471-80
AB  - Ninety strains of fungi from the collection of our mycology laboratory were 
      tested in Galzy and Slonimski (GS) synthetic liquid medium for their ability to 
      degrade the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and its by-product, 
      2,4-dichlorophenol (2,4-DCP) at 100 mg l(-1), each. Evolution of the amounts of 
      each chemical in the culture media was monitored by HPLC. After 5 days of 
      cultivation, the best results were obtained with Aspergillus penicilloides and 
      Mortierella isabellina for 2,4-D and with Chrysosporium pannorum and Mucor 
      genevensis for 2,4-DCP. The data collected seemed to prove, on one hand, that the 
      strains responses varied with the taxonomic groups and the chemicals tested, and, 
      on the other hand, that 2,4-D was less accessible to fungal degradation than 
      2,4-DCP. In each case, kinetics studies with the two most efficient strains 
      revealed that there was a lag phase of 1 day before the onset of 2,4-D 
      degradation, whereas there was none during 2,4-DCP degradation. Moreover, 2,4-DCP 
      was detected transiently during 2,4-D degradation. Finally, M. isabellina 
      improved its degradation potential in Tartaric Acid (TA) medium relative to GS 
      and Malt Extract (ME) media.
