Less is known about the pathways of PAH degradation by co-cultures than about the pathways of degradation by individual bacteria and fungi (Juhasz Naidu, 2000). Four bacteria Pseudomonas aeruginosa, Pseudomonas cepacia (=Burkholderia cepacia). Pseudomonas sp. and Ralstonia pickettii) and four fungi (Alternaria tenuis, Aspergillus terreus, Trichoderma... 

Trichloroethene and aromatic compounds — A striking example is the degradation of trichloroethene by different strains of Pseudomonas sp. grown with phenol (Folsom et al. 1990) or with toluene. This capability has already been noted in Section 4.4.1.1 in the context of monooxygenase reactions, and has attracted attention for the bioremediation of contaminated sites (Hopkins and McCarty 1995). Conversely, toluene degradation is induced (a) by trichloroethene in a strain of P. putida (Heald and Jenkins 1994) and (b) in P. mendocina — although not in Burkholderia (Pseudomonas) cepacia or P. putida strain FI — by trichloroethene, pentane, and... 

The degradation of 2,4,5-trichlorophenoxyacetate by Burkholderia (Pseudomonas) cepacia AC1100 (Haugland et al. 1990 Daubaras et al. 1995) proceeds via 2,4,5-trichlorophenol that is degraded by initial oxygenation to 2,5-dichlorohydroquinone. This strain also brings about para-hydroxylation of dichlorophenols, whether or not this position carries a chlorine substituent (Tomasi et al. 1995). 

Baeyer-Villiger oxidation has also been reported for aliphatic ketones. Several strains able to grow on various aliphatic or alicyclic substrates have been isolated, and it has been shown that their degradation often involves a Baeyer-Villiger oxidation. For example, it has beeen observed that Pseudomonas multivorans, Pseudomonas aeruginosa, Pseudomonas cepacia and Nocardia sp. are able to grow on tridecan-2-one l25-28l.
