Imaging Approaches to Assessments of Toxicological Oxidative Stress Using Genetically-encoded Fluorogenic Sensors

While oxidative stress is a commonly cited toxicological mechanism, conventional methods to study it suffer from a number of shortcomings, including ...

A bacterial strain designated Ca6T was isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated soil from the site of a former manufactured gas plant in Charlotte, NC, USA, and linked phylogenetically to the family Rhodocyclaceae of the class Betaproteobacteria. Its 16S rRNA gene sequence was highly similar to globally distributed environmental sequences, including those previously designated 'Pyrene Group 1' demonstrated to grow on the PAHs phenanthrene and pyrene by stable-isotope probing. The most closely related described relative was Sulfuritalea hydrogenivorans strain sk43HT (93.6 % 16S rRNA gene sequence identity). In addition to a limited number of organic acids, Ca6T was capable of growth on the monoaromatic compounds benzene and toluene, and the azaarene carbazole, as sole sources of carbon and energy. Growth on the PAHs phenanthrene and pyrene was also confirmed. Optimal growth was observed aerobically under mesophilic temperature, neutral pH and low salinity conditions. Major fatty acids present included summed feature 3 (C16 : 1ω7c or C16 : 1ω6c) and C16 : 0. The DNA G+C content of the single chromosome was 55.14  mol% as determined by complete genome sequencing. Due to its distinct genetic and physiological properties, strain Ca6T is proposed as a member of a novel genus and species within the family Rhodocyclaceae, for which the name Rugosibacter aromaticivorans gen. nov., sp. nov. is proposed. The type strain of the species is Ca6T (=ATCC TSD-59T=DSM 103039T).

Rugosibacter aromaticivorans gen. nov., sp. nov., a bacterium within the family Rhodocyclaceae, isolated from contaminated soil, capable of degrading aromatic compounds.

Erratum: Rugosibacter aromaticivorans gen. nov., sp. nov., a bacterium within the family Rhodocyclaceae, isolated from contaminated soil, capable of degrading aromatic compounds.
