1. Evaluation of hematite and quartz flotation kinetics using surfactant produced by Rhodococcus erythropolis as bioreagent
Abstract The use of biosurfactants as reagents represents a promising alternative to the conventional surfactants used in the mineral industry because they may present low toxicity and high biodegradability. Therefore, this research studied the hematite and quartz flotation kinetics using surfactant produced by Rhodococcus erythropolis as bioreagent. The flo

2. Response of Rhodococcus erythropolis strain IBBPo1 to toxic organic solvents
Abstract Recently, there has been a lot of interest in the utilization of rhodococci in the bioremediation of petroleum contaminated environments. This study investigates the response of Rhodococcus erythropolis IBBPo1 cells to 1% organic solvents (alkanes, aromatics). A combination of microbiology, biochemical, and molecular approaches were used to examine

3. Biodegradation of crude oil by individual bacterial strains and a mixed bacterial consortium
Three bacterial isolates identified as Alcanivorax borkumensis SK2, Rhodococcus erythropolis HS4 and Pseudomonas stutzeri SDM, based on 16S rRNA gene sequences, were isolated from crude oil enrichments of natural seawater. Single strains and four bacterial consortia designed by mixing the single bacterial cultures respectively in the following ratios: (Alcan

4. Nova Técnica de END Baseada em Células Bacterianas para Detecção de Micro e Nano Defeitos Superficiais
ResumoTrabalhos recentes têm demostrado que filmes com células bacterianas (CB) podem ser usados como uma nova técnica de Ensaios Não Destrutivos (END) fiável para a deteção e caracterização de micro e nano defeitos superficiais. As CB podem ser usadas também numa perspetiva de caracterização da textura e topografia de superfícies. Esta nova té

5. Biosurfactant production by Rhodococcus erythropolis and its application to oil removal
The influence of different nutrients on biosurfactant production by Rhodococcus erythropolis was investigated. Increasing the concentration of phosphate buffer from 30 up through 150 mmol/L stimulated an increase in biosurfactant production, which reached a maximum concentration of 285 mg/L in shaken flasks. Statistical analysis showed that glycerol, NaNO3,M

6. Case Report: Rhodococcus erythropolis Osteomyelitis in the Toe
The Rhodococcus species rarely cause musculoskeletal infections, with only two cases reported in the literature. We report the case of a 53-year-old woman who had an infection develop after first metatarsophalangeal joint fusion. A year after surgery, she continued to have pain and swelling with nonunion. She underwent revision of the arthrodesis and tissue

7. Three of the seven bphC genes of Rhodococcus erythropolis TA421, isolated from a termite ecosystem, are located on an indigenous plasmid associated with biphenyl degradation.
Rhodococcus erythropolis TA421, a polychlorinated biphenyl and biphenyl degrader isolated from a termite ecosystem, has seven bphC genes expressing 2,3-dihydroxybiphenyl dioxygenase activity. R. erythropolis TA421 harbored a large and probably linear plasmid on which three (bphC2, bphC3, and bphC4) of the seven bphC genes were located. A non-biphenyl-degradi

8. Transposition of the IS21-related element IS1415 in Rhodococcus erythropolis.
Three copies of the IS21-related transposable element IS1415 were identified in Rhodococcus erythropolis NI86/21. Adjacent to one of the IS1415 copies, a 47-bp sequence nearly identical to the conserved 5' end of integrons was found. Accurate transposition of IS1415 carrying a chloramphenicol resistance gene (Tn5561) was demonstrated following delivery from

9. Cesium Accumulation and Growth Characteristics of Rhodococcus erythropolis CS98 and Rhodococcus sp. Strain CS402
Growth and cesium accumulation characteristics of two cesium-accumulating bacteria isolated from soils were investigated. Rhodococcus erythropolis CS98 and Rhodococcus sp. strain CS402 accumulated high levels of cesium (approximately 690 and 380 μmol/g [dry weight] of cells or 92 and 52 mg/g [dry weight] of cells, respectively) after 24 h of incubation in t

10. Thiocarbamate herbicide-inducible nonheme haloperoxidase of Rhodococcus erythropolis NI86/21.
During biodegradation of thiocarbamate herbicides by Rhodococcus erythropolis NI86/21, a protein with an M(r) of 30,000 is induced (I. Nagy, G. Schoofs, F. Compernolle, P. Proost, J. Vanderleyden, and R.De Mot, J. Bacteriol. 177:676-687, 1995). Based on N-terminal sequence data for the protein purified by two-dimensional electrophoresis, the corresponding st

11. Characterization of muconate and chloromuconate cycloisomerase from Rhodococcus erythropolis 1CP: indications for functionally convergent evolution among bacterial cycloisomerases.
Muconate cycloisomerase (EC 5.5.1.1) and chloromuconate cycloisomerase (EC 5.5.1.7) were purified from extracts of Rhodococcus erythropolis 1CP cells grown with benzoate or 4-chlorophenol, respectively. Both enzymes discriminated between the two possible directions of 2-chloro-cis, cis-muconate cycloisomerization and converted this substrate to 5-chloromucon

12. Hydride-Meisenheimer Complex Formation and Protonation as Key Reactions of 2,4,6-Trinitrophenol Biodegradation by Rhodococcus erythropolis
Biodegradation of 2,4,6-trinitrophenol (picric acid) by Rhodococcus erythropolis HLPM-1 proceeds via initial hydrogenation of the aromatic ring system. Here we present evidence for the formation of a hydride-Meisenheimer complex (anionic ς-complex) of picric acid and its protonated form under physiological conditions. These complexes are key intermediates o
