TI  - Effects of different culture media on biodegradation of triclosan by Rhodotorula 
      mucilaginosa and Penicillium sp.

AB  - Triclosan is an antimicrobial agent and a persistent pollutant. The 
      biodegradation of triclosan is dependent on many variables including the 
      biodegradation organism and the environmental conditions. Here, we evaluated the 
      triclosan degradation potential of two fungi strains, Rhodotorula mucilaginosa 
      and Penicillium sp., and the rate of its turnover to 2,4-dichlorophenol 
      (2,4-DCP). Both of these strains showed less susceptibility to triclosan when 
      grown in minimal salt medium. In order to further evaluate the effects of 
      environmental conditions on triclosan degradation, three different culture 
      conditions including original thermal power plant wastewater, T6 nutrimedia and 
      ammonium mineral salts medium were used. The maximum triclosan degradation yield 
      was 48% for R. mucilaginosa and 82% for Penicillium sp. at 2.7 mg/L triclosan 
      concentration. Biodegradation experiments revealed that Penicillium sp. was more 
      tolerant to triclosan. Scanning electron microscopy micrographs also showed the 
      morphological changes of fungus when cells were treated with triclosan. Overall, 
      these fungi strains could be used as effective microorganisms in active uptake 
      (degradation) and passive uptake (sorption) of triclosan and their efficiency can 
      be increased by optimizing the culture conditions.
