The present study describes the behavior of a natural phenanthrene-degrading consortium (CON), synthetic (constructed with isolated strains from CON) and an strain form CON (Sphingobium sp. AM) in phenanthrene cultures to understand interactions among microorganisms during degradation as sole carbon energy source liquid cultures. In contaminant assay, defined not only achieved major percentage (> 95%) but also showed more efficient elimination intermediate metabolite. opposite occurred...
The effect of bioaugmentation with Sphingobium sp. AM strain on different soils microbiomes, pristine soil (PS), chronically contaminated (IPK) and recently (Phe) their implications in bioremediation efficiency was studied by focusing the ecology that drives bacterial communities response to inoculation. draft genome codifies genes for metabolism aromatic aliphatic hydrocarbons. In Phe, inoculation improved elimination phenanthrene during whole treatment, whereas IPK no improvement...
Two synthetic bacterial consortia (SC) composed of strains Sphingobium sp. (AM), Klebsiella aerogenes (B), Pseudomonas (Bc-h and T), Burkholderia (Bk) Inquilinus limosus (Inq) isolated from a natural phenanthrene (PHN)-degrading consortium (CON) were developed evaluated as an alternative approach to PHN biodegradation in bioremediation processes. A metabolic network showing the potential role was reconstructed by silico study six genomes classification dioxygenase enzymes using RHObase...
Abstract Background Bioaugmentation is considered a sustainable and cost-effective methodology to recover contaminated environments, but its outcome highly variable. Predation key top-down control mechanism affecting inoculum establishment, however, effects on this process have received little attention. This study focused the impact of trophic interactions bioaugmentation success in two soils with different pollution exposure histories. We inoculated 13 C-labelled pollutant-degrading...
Aims: The objective of this study was to apply the knowledge-based approach selection an inoculum be used in bioaugmentation processes facilitate phenanthrene degradation phenanthrene- and Cr(VI)-co-contaminated soils. Methods Results: bacterial community composition microcosms, determined by denaturing gradient gel electrophoresis analysis, showed that members Sphingomonadaceae family were predominant micro-organisms. However, Cr(VI) contamination produced a selective change Sphingomonas...
To analyse the physiological response of Sphingobium sp. 22B to water stress.The strain was grown under excess carbon source and then subjected low (60RH) high (18RH) stress conditions for 96 h. Quantification trehalose, glycogen, polyhydroxybutyrate (PHB) transmission electron microscopy (TEM) studied. Genes linked with desiccation were searched in Sphingomonas 'sensu latu' genomes their transcripts quantified by real-time PCR. Results showed that, absence stress, accumulated 4·76 ± 1·41%...
Monitored natural recovery (MNR) is an in situ technique of conventional remediation for the treatment contaminated sediments that relies on processes to reduce bioavailability or toxicity contaminants. Metabarcoding and bioinformatics approaches infer functional prediction were applied bottom a tributary drainage channel Río de La Plata estuary, order assess biological contribution MNR. Hydrocarbon concentration water samples surface was below detection limit. Surface represented with high...
ABSTRACT Sphingobium sp. 22B is a polycyclic aromatic hydrocarbon–degrading strain isolated from Patagonia, Argentina, with capabilities to withstand the environmental factors of that semiarid region. The draft genome shows presence genes related responses carbon starvation and drying conditions.
