Abstract
Summary: Isolates of 26 fungal species from broiler house litter were screened for their ability to metabolize and methylate 2,3,4,6-tetrachlorophenol over a five-day period, by adding the chlorophenol to cultures after mycelial pellets were established on a complete growth medium. Under these conditions, 99 of the 116 isolates tested metabolized the chlorophenol and 68 of these produced 2,3,4,6-tetrachloro-anisole. The proportion of the chlorophenol methylated to the chloroanisole differed widely with the isolate, even within species. The highest methylation was observed with Penicillium corylophilum; certain other isolates, notably of P. brevicompactum, metabolized almost all the chlorophenol without forming the chloroanisole. Progress studies with these species suggested that there is more than one route for the metabolism of 2,3,4,6-tetrachlorophenol. In tests with suspensions of mixed bacterial populations from broiler house litter, the chlorophenol was metabolized but no methylation was detected.
