[The microbial transformation of phenanthrene and anthracene].

The transformation of phenanthrene and anthracene by Rhodococcus rhodnii 135, Pseudomonas fluorescens 26K, and Arthrobacter sp. K3 is studied. Twenty-one intermediates of phenanthrene and anthracene transformation are identified by HPLC, mass spectrometry, and NMR spectroscopy.

[Fluorene degradation by bacteria of the genus Rhodococcus].

Of the four investigated Rhodococcus strains (R. rhodochrous 172, R. opacus 4a and 557, and R.

[Fluorene cometabolism by Rhodococcus rhodochrous and Pseudomonas fluorescens].

The transformation of fluorene by Rhodococcus rhodochrous strain 172 grown on sucrose and Pseudomonas fluorescens strain 26K grown on glycerol was studied as a function of the substrate concentration and the growth phase. Under certain cultivation conditions, fluorene was completely consumed from the medium. The specific transformation rate of fluorene was considerably higher when it was transformed in the presence of the cosubstrates than when it served as the sole carbon source.

[Dependence of transformation of chlorophenols by Rhodococci on position and number of chlorine atoms in the aromatic ring].

Study of the conversion of chlorophenols by Rhodococcus opacus 1G, R. rhodnii 135, R. rhodochrous 89, and R.
