 Title    -octaethyl-porphodimethene-thallium(III) Chloride  
 Abstract    The crystal structure of the title com pound was determined in order to obtain structural information on a tetrapyrrole bearing meso-oxo-functions. C36H 4,N 40 2T1C1 • C H 3OH, P 1, a = 10.358(2), b = 12.344(3), c = 15.490(3) Ä, a = 84.36(2)°, ß = 78.53(2)°, y = 82.26(2)°, V = 1918.2(7) Ä3, Z = 2, 130 K, R = 0.04 for 6749 reflections with I > 4er(I). The structure consists of the penta-coordinated thallium ligated by the four nitrogens of the porphodimethene ligand and a chloride in the axial position. The central macrocycle shows some degree of ruffling with the carbonyl groups pointing slightly above and below the mean plane of the molecule.

 Title    Degradation of Pentachlorophenol by Mycena avenacea TA 8480 - Identification of Initial Dechlorinated Metabolites  
 Abstract    Cultures o f the basidiomycete M ycena avenacea TA 8480 were shown to m etabolize penta­ chlorophenol (PCP), 2,3,5,6-tetrachloro-/7-hydroquinone (TeCHQ), and 2,3,5,6-tetrachloro-/?-benzoquinone (TeCBQ). The first metabolite o f the PCP degradation pathway was identified as TeCBQ which in a second reaction is reduced to the hydroquinone TeCHQ. Subsequently dechlorination o f TeCHQ yielded 3,5,6-trichloro-2-hydroxy-/?-benzoquinone (TCOHBQ). The specific degradation rate for PCP was 1.4 mg x g dry m ycelia-1 x day-1. The initial de­ chlorination rate o f TeCHQ was 5.9 mg x g dry m ycelia"1 x h o u r '1. N one o f the com pounds supported growth o f the fungus.
