چکیده
Pseudonocardia dioxanivorans CB1190 is the first bacterium reported to be capable of growth on the environmental contaminant 1,4-dioxane and the first member of the genus Pseudonocardia for which there is an annotated genome sequence. Preliminary analysis of the genome (chromosome and three plasmids) indicates that strain CB1190 possesses several multicomponent monooxygenases that could be involved in the aerobic degradation of 1,4-dioxane and other environmental contaminants.

Pseudonocardia dioxanivorans sp. nov., a novel actinomycete that grows on 1,4-dioxane.
An actinomycete strain (CB1190(T)) was previously isolated from industrial sludge contaminated with 1,4-dioxane. The cells of this culture are Gram-positive and exhibit branching aerial and vegetative mycelium. Analysis of the 16S rRNA gene sequence indicates that the strain belongs to the genus Pseudonocardia, closely related to Pseudonocardia hydrocarbonoxydans, P. sulfidoxydans and P. haloph...
متن کاملIdentification of biomarker genes to predict biodegradation of 1,4-dioxane.
Bacterial multicomponent monooxygenase gene targets in Pseudonocardia dioxanivorans CB1190 were evaluated for their use as biomarkers to identify the potential for 1,4-dioxane biodegradation in pure cultures and environmental samples. Our studies using laboratory pure cultures and industrial activated sludge samples suggest that the presence of genes associated with dioxane monooxygenase, propa...
متن کاملGlyoxylate metabolism is a key feature of the metabolic degradation of 1,4-dioxane by Pseudonocardia dioxanivorans strain CB1190.
The groundwater contaminant 1,4-dioxane (dioxane) is transformed by several monooxygenase-expressing microorganisms, but only a few of these, including Pseudonocardia dioxanivorans strain CB1190, can metabolize the compound as a sole carbon and energy source. However, nothing is yet known about the genetic basis of dioxane metabolism. In this study, we used a microarray to study differential ex...
متن کاملDraft Genome Sequence of Pseudonocardia sp. Strain N23, a 1,4-Dioxane-Degrading Bacterium
Pseudonocardia sp. strain N23 is a 1,4-dioxane-degrading bacterium that is capable of utilizing 1,4-dioxane as the sole carbon and energy source. Here, we report the draft genome sequence of strain N23, with a size of 6.5 Mbp, to identify the genes associated with 1,4-dioxane degradation.

1,4-Dioxane biodegradation was investigated in microcosms prepared with groundwater and soil from an impacted site in Alaska. In addition to natural attenuation conditions (i.e., no amendments), the following treatments were tested: (a) biostimulation by addition of 1-butanol (a readily available auxiliary substrate) and inorganic nutrients; and (b) bioaugmentation with Pseudonocardia dioxanivo...
