Conjugation of extrachromosomal replicons of Rhodococcus erythropolis AN12
… to the Gram-positive actinomycete species, Rhodococcus erythropolis, are diverse not only in terms of metabolic potentials but the plasmids they encode. Pulsed-field gel electrophoresis (PFGE) revealed three previously uncharacterized megaplasmids in the genome of Rhodococcus erythropolis …

Iron Acquisition in <em>Rhodococcus erythropolis</em> Strain IGTS8: Characterization of a Mutant Strain that Over Produces Siderophore.
… the transport of iron by the soil bacterium <em>Rhodococcus erythropolis</em>. To fulfill this aim, mutant strains of the bacteria were screened for those that overproduce siderophore. Often, a bacterium will over produce siderophore to compensate for a defect in transport. One such mutant, …

Iron Acquisition in <em>Rhodococcus erythropolis</em> Strain IGTS8: Characterization of a Mutant that Does Not Produce a Siderophore.
… a siderophore deficient mutant strain of <em>Rhodococcus erythropolis</em> strain IGTS8 (IGTS8) was investigated to learn more about how this poorly characterized bacterium acquires iron. N5-59 cells were starved for iron and then lysed to release any intracellular siderophore. No …

Discovery and Characterization of an Antibiotic from the Soil Bacterium <em>Bacillus</em> sp.
… the rise of antibiotic resistant pathogens. <em>Rhodococcus</em>, an actinomycete related to the prolific antibiotic producing genus <em>Streptomyces</em>, harbors over 30 genes for secondary metabolism that could be involved in antibiotic production. Several antibiotics have already been …

Characterization of arsenic-binding siderophores from environmental bacteria and evaluation of their role in arsenic tolerance
… these, four strains belonging to the species Rhodococcus erythropolis, Arthrobacter oxydans and Kocuria rosea were selected, in addition to the previously isolated Rhodococcus erythropolis S43, for a more detailed study. The isolates were used to produce siderophore extracts, which were then …

GENOMIC AND PHYSIOLOGICAL INSIGHTS INTO BACTERIAL HEAVY METAL RESISTANCE MECHANISMS FOR ENVIRONMENTAL DECONTAMINATION
… Genome sequencing and transcriptomic analysis of Rhodococcus erythropolis strain SC26 provide insights into its Cr(VI) reduction pathways; (3) Characterization of Cd resistance and plant growth-promoting (PGP) bacteria contributes to knowledge of plant-microbial interactions to alleviate Cd stress …

Mechanistic understanding of microbial desulfurization
… consisting of a resting cell suspension of Rhodococcus erythropolis IGTS8 mixed with hexadecane containing dibenzothiophene (DBT). DBT has become the model compound in BDS studies because its alkyalted derivatives are highly recalcitrant to HDS. Biocatalyst aggregation was found to be …

From Flare to Repair: Commensal Bacteria's Influence on Inflammation and Wound Healing
… Two candidate bacteria, Delftia acidovorans and Rhodococcus erythropolis were sufficient to initiate the lung inflammation in the IL-10 deficient mice. Transplantation of human fecal microbiota also induced gut inflammation followed by lung inflammation in the IL-10 deficient mice. In Chapter 4 …

Exploring the Potential of Algae-Bacteria Communities For Biotechnology
… involving the non-Rhizobiales bacterium Rhodococcus erythropolis and L. rostrata. This novel interaction, together with interaction of the more industrially relevant Chlamydomonas reinhardtii strain was characterized. Nitrogen is a major limiting nutrient for industrial scale algal …

Enzymatic degradation of egg yolk cholesterol
… from Pseudomonas fluorescens (Pf), Nocardia erythropolis (Ne), Brevibacterium species (Bs) and Streptomyces species (Ss), and cholesterol reductase isolated from cucumber leaves to degrade cholesterol in egg yolk was investigated. Incubation of egg yolk with a cholesterol reductase for 72h at …

Biodegradation of RDX in Rhodococcus spp.
… been isolated from RDX polluted sites including Rhodococcus rhodochrous 11Y. The RDX degrading genes, xplA and xplB encoding a novel flavodoxin fused cytochrome P450 and its reductase partner respectively, were first identified in R. rhodochrous 11Y. This unusual P450 system has now been found in …

Screening for novel cold-adapted nitrile hydratases in Antarctic metagenornic libraries
Nitrile hydratases (NHase) catalyse the hydrolysis of nitriles to their corresponding amides, the first step in the nitrile degradation pathway. The second step is the conversion of the amide to a carboxylic acid, catalysed by an amidase. The NHases published to date have been isolated from …

EVALUATION DE L’IMPACT DES PROPRIÉTÉS TENSIOACTIVES ET D’HYDROPHOBICITÉ DE SURFACE SUR LE TRANSFERT GAZ-LIQUIDE AU SEIN D’UN RÉACTEUR BIPHASIQUE ET SON EXTRAPOLATION
Ce travail de fin d'étude est situé dans le contexte général du traitement biologique des effluents gazeux et en particulier dans l’utilisation, à cette fin, de réacteurs biphasiques (TPPB). Les précédentes études réalisées sur le sujet ont permis de caractériser les potentialités, notamment en …
