    Abstract Biodegradative characteristics were investigated for the commercially available mixtures of polychlorinated biphenyls (PCBs) Trikhlorbifenil and Sovol degraded by the Rhodococcus wratislaviensis КT112-7, Rhodococcus wratislaviensis CH628 and Rhodococcus ruber P25 strains isolated from the natural habitats. For bioutilization of the Trikhlorbifenil, all three strains were found to have a high biodegrading potential: the complete destruction was achieved in 10-14 days. For the mixture Sovol, the bioutilization parameters were found to be of lower values: the degradation of the PCBs congeners was 96-98% after 14 days. For the tested polychlorobiphenyl mixtures, the structural specificities of congeners are discussed, the genes encoding monooxygenases are revealed, and explanation is given to the differences in biodegradative characteristics of the Rhodococcus strains towards di-, tri-, tetra-, penta-, hexa- and heptachlorobiphenyls. The presented data are highly relevant for environmental remediation of objects polluted with the extremely hazardous polychlorobiphenyls.

    Abstract We report the 5,728,255-bp draft genome sequence of Rhodococcus ruber P25, isolated from a soil polluted with halogenated aromatic compounds in the city of Perm, Russia. The strain degrades polychlorinated biphenyls and a broad range of aromatic compounds. It possesses genes that mediate the degradation of biphenyls/polychlorinated biphenyls, naphthalene, and monoaromatic compounds.

    Abstract Halomonads are moderately halophilic bacteria that are studied as models of prokaryotic osmoadaptation and sources of enzymes and chemicals for biotechnological applications. Despite the progress in understanding the diversity of these organisms, our ability to explain ecological, metabolic, and biochemical traits of halomonads at the genomic sequence level remains limited. This study addresses this gap by presenting draft genomes of

    Abstract This work investigated the distribution of the clcF gene in actinobacteria isolated from different ecotopes. The gene encodes chloromuconolactone dehalogenase (CMLD) ClcF, the enzyme found to date in only one representative of Gram‐positive bacteria, Rhodococcus opacus 1CP, adapted to 2‐chlorophenol (2CP). Using primers specific to the clcF gene, from the DNA matrix of rhodococcal strains closely related to species Rhodococcus wratislaviensis (P1, P12, P13, P20, G10, KT112, KT723, BO1) we obtained PCR products whose nucleotide sequences were 100% identical to that of the clcF gene from strain R. opacus 1CP. CMLDs isolated from the biomass of strains Rhodococcus spp. G10 and P1 grown on 2CP did not differ by their subunit molecular mass deduced from the known amino acid sequence of the clcF gene from the ClcF of strain R. opacus 1CP. Matrix‐assisted laser dissociation/ionization time‐of‐flight mass spectrometry showed the presence of a peak with m / z 11,194–11,196 Da both in whole cells and in protein solutions with a ClcF activity. Thus, we have first time shown the distribution of ClcF among actinobacteria isolated from geographically distant habitats.

    Abstract Eight moderately halotolerant naphthalene-degrading strains of the genus Rhodococcus isolated from soil samples and slime pit bottom sediment of the Verkhnekamsk salt mining region of Russia were characterized by PCR amplification of repetitive bacterial DNA elements (rep-PCR) and identified by 16S ribosomal RNA gene sequence analysis. The diversity of their dioxygenase (nar-like) genes was investigated as these genes are known to be involved in naphthalene-degradation. The analysis of the nar-like genes identified revealed their heterogeneity in the strains under study and identity to the known sequences of nar-like genes of previously characterized from members of the genus Rhodococcus.

    Abstract The present review describes some aspects of organization of biodegradative pathways of Nocardioform microorganisms, first of all, with respect to their ability to degrade aromatic compounds, mostly methylbenzoate, chlorosubstituted phenols, and chlorinated biphenyls and the intermediates of their transformation: 4-chlorobenzoate and para-hydroxybenzoate. Various enzyme systems induced during degradation processes are defined. The ability of microorganisms to induce a few key enzymes under the influence of xenobiotics is described. This ability may increase the biodegradative potential of strains allowing them to survive in the changing environment or demonstrate to some extent the unspecific response of microorganisms to the effect of toxicants. Nocardioform microorganisms responsible for degradation of such persistent compounds as polychlorinated biphenyls, polyaromatic hydrocarbons, chlorinated benzoates and phenols and other xenobiotics are characterized. The possibility of using Nocardioform microorganisms in some aspects of biotechnology due to their ability to produce some compounds important for industry is also estimated.
