Assessing the receptor-mediated activity of PAHs using AhR-, ERα- and PPARγ- CALUX bioassays
activity whilst B(a)P exhibited both agonistic and antagonistic activity (lowering E2 activity by 30%). Phenanthrene and anthracene had weak ER α agonist activities. These results indicate that certain PAH ...
Assessing the endocrine activity of PAHs using the DRE-, ERE- and PPARγ CALUX bioassays
significant agonistic activity. 3) The ERE- CALUX: So far, only preliminary range finding results were obtained, showing that phenanthrene, naphthalene, chrysene, fluoranthene and pyrene all show agonistic ...
A non-invasive fluorescent staining procedure allows Confocal Laser Scanning Microscopy based imaging of Mycobacterium in multispecies biofilms colonizing and degrading polycyclic aromatic hydrocarbons.
VM552, the GFP labeled PAH-degrading Sphingomonas sp. LH128- GFP and DsRed-labeled Pseudomonas putida OUS82 (RF), and colonizing a glass substrate coated with phenanthrene crystals in flow chambers. CLSM ...
Characterization of cultures enriched from acidic polycyclic aromatic hydrocarbon-contaminated soil for growth on pyrene at low pH.

Distribution of the Mycobacterium community and polycyclic aromatic hydrocarbons (PAHs) among different size fractions of a long-term PAH-contaminated soil.
majority of the PAH s and showed immediate pyrene- and phenanthrene-mineralizing activity upon addition of (14)C-labelled pyrene or phenanthrene. In contrast, the sand and silt fractions showed a lag time of ...

Use of the pAL5000 replicon in PAH-degrading mycobacteria: application for strain labelling and promoter probing.
Genetic Recombinant Proteins Sequence Analysis, DNA Transformation, Bacterial Abstract: Three environmental Mycobacterium strains (LB501T, LB307T and VM552) able to degrade anthracene, phenanthrene or ...
A transcriptional luxAB reporter fusion responding to fluorene in Sphingomonas sp. LB126 and its initial characterisation for whole-cell bioreporter purposes.
polycyclic aromatic hydrocarbons phenanthrene and dibenzothiophene, whereas strong responses were obtained with 9-fluorenone, 9-hydroxyfluorene, phthalic acid and protocatechuic acid. The latter four compounds ...
Differential responses of eubacterial, Mycobacterium, and Sphingomonas communities in polycyclic aromatic hydrocarbon (PAH)-contaminated soil to artificially induced changes in PAH profile.
