“…The strain was identifi ed and maintained at the Czech Collection of Microorganisms (CCM), Masaryk University, Brno, Czech Republic. The strain was negatively evaluated as containing bphA gene encoding biphenyl dioxygenase (the fi rst enzyme of PCB degradation pathway) in nucleus DNA however did not question the possibility of presence of plasmid bphA gene (Tandlich et al 2001). as solutions in DMSO.…”

The effect of polychlorinated biphenyls on biomass production, lipid accumulation, and on the fatty acid profi le of the major membrane lipids of Alcaligenes xylosoxidans isolated from a soil long-term contaminated with polychlorinated biphenyls was examined. The lowest bacterial growth was observed in the presence of biphenyl and polychlorinated biphenyls. On the other hand, the highest growth stimulation was observed in the presence polychlorinated biphenyls. Higher growth ability was observed when polychlorinated biphenyls or 3-chlorobenzoic acid were added after three days of cultivation. Higher lipid accumulation corresponded with lower growth ability. The importance of time when bacterial strain meets polychlorinated biphenyls or 3-chlorobenzoic acid should be emphasized. The addition of toxic organic compound later in stationary growth phase led to better survival and evoked lower membrane adaptation. However, polychlorinated biphenyls or 3-chlorobenzoic acid amendment at the beginning of cultivation stimulated adaptation responses as membrane saturation, cis to trans isomerisation, and branched fatty acids alteration and decreased growth ability. Palmitic acid and 17-cyclopropyl fatty acid were observed as prevalent in the bacterial membrane as well as in the total lipids.

“…The strain was isolated by Donna Bedard (Bedard et al 1986). Both strains were positively evaluated as containing bphA gene encoding biphenyldioxygenase, the first and key enzyme of biphenyl metabolic pathway (Tandlich et al 2001).…”

“…Biphenyl is a known inducer of the bacterial PCB metabolic pathway and several plant compounds, including flavonoids (Furukawa et al 1978;Donnelly et al 1994) and lignin (Furukawa 1982), as well as synthetic terpenes such as carvone and limonene (Gilbert and Crowley 1997;Hernandez et al 1997;Tandlich et al 2001;Dercová et al 2003) were shown to promote PCB degradation by PCBdegrading bacteria. Several articles also describe the enhancing effect of plant containing terpenes, e.g., pine needles, eucalypt and ivy leaves, tangerine and orange peel on the degradation ability of different bacterial strains (Hernandez et al 1997;Dzantor et al 2002;Kwon et al 2009).…”

In this study, we examined the effect of polychlorinated biphenyls (PCBs) in the presence of natural and synthetic terpenes and biphenyl on biomass production, lipid accumulation, and membrane adaptation mechanisms of two PCB-degrading bacterial strains Pseudomonas stutzeri and Burkholderia xenovorans LB400. According to the results obtained, it could be concluded that natural terpenes, mainly those contained in ivy leaves and pine needles, decreased adaptation responses induced by PCBs in these strains. The adaptation processes under investigation included growth inhibition, lipid accumulation, composition of fatty acids, cis/trans isomerization, and membrane saturation. Growth inhibition effect decreased upon addition of these natural compounds to the medium. The amount of unsaturated fatty acids that can lead to elevated membrane fluidity increased in both strains after the addition of the two natural terpene sources. The cells adaptation changes were more prominent in the presence of carvone, limonene, and biphenyl than in the presence of natural terpenes, as indicated by growth inhibition, lipid accumulation, and cis/trans isomerization. Addition of biphenyl and carvone simultaneously with PCBs increased the trans/cis ratio of fatty acids in membrane fractions probably as a result of fluidizing effects of PCBs. This stimulation is more pronounced in the presence of PCBs as a sole carbon source. This suggests that PCBs alone have a stronger effect on bacterial membrane adaptation mechanisms than when added together with biphenyl or natural or synthetic terpenes.

“…For example, carvone and limonene, the principal components of spearmint and lemon oil are able to induce PCB biotransformation in Arthrobacter sp. B1B, Alcaligenes eutrophus, and Pseudomonas stutzeri (Gilbert and Crowley 1997;Koh et al 2000;Tandlich et al 2001). In addition, the application of plant materials rich in essential oil such as orange peels, ivy leaves, pine needles or eucalyptus leaves to contaminated soil was reported to stimulate the growth of biphenyl utilizers and simultaneously induce Aroclor 1242 and 1248 degradation (Hernandez et al 1997;Dzantor and Woolston 2001).…”

Trichloroethylene cometabolic degradation by Rhodococcus sp. L4 induced with plant essential oils

Cometabolic degradation of TCE by toluene-degrading bacteria has the potential for being a cost-effective bioremediation technology. However, the application of toluene may pose environmental problems. In this study, several plant essential oils and their components were examined as alternative inducer for TCE cometabolic degradation in a toluene-degrading bacterium, Rhodococcus sp. L4. Using the initial TCE concentration of 80 microM, lemon and lemongrass oil-grown cells were capable of 20 +/- 6% and 27 +/- 8% TCE degradation, which were lower than that of toluene-grown cells (57 +/- 5%). The ability of TCE degradation increased to 36 +/- 6% when the bacterium was induced with cumin oil. The induction of TCE-degrading enzymes was suggested to be due to the presence of citral, cumin aldehyde, cumene, and limonene in these essential oils. In particular, the efficiency of cumin aldehyde and cumene as inducers for TCE cometabolic degradation was similar to toluene. TCE transformation capacities (T (c)) for these induced cells were between 9.4 and 15.1 microg of TCE mg cells(-1), which were similar to the known toluene, phenol, propane or ammonia degraders. Since these plant essential oils are abundant and considered non-toxic to humans, they may be applied to stimulate TCE degradation in the environment.
