| pseudo-membranes on internal organs associated with rhodococcus qingshengii infection in atlantic salmon (salmo salar). | this paper describes a pathological condition in intensive reared atlantic salmon (salmo salar), restricted to the appearance of pseudo-membranes covering internal organs (i.e. spleen, liver, heart and others) associated with the presence of large numbers of a gram-positive bacteria. isolate 79043-3, obtained as pure culture from affected fish, was subjected to a polyphasic taxonomic study in order to determine its exact taxonomic position, as well as to experimental challenges leading to determ ... | 2011 | 20580498 |
| biosynthesis of 2-amino-2,3-dimethylbutyramide by nitrile hydratase from a newly isolated cyanide-resistant strain of rhodococcus qingshengii. | cells of a new isolate of rhodococcus qingshengii harboring nitrile hydratase converted 2-amino-2,3-dimethylbutyronitrile into 2-amino-2,3-dimethylbutyramide (adba). cells also hydrated a broad range of substrates including saturated, unsaturated and cyclic aliphatic nitriles. the microorganism tolerated kcn and adba up to 5 mm and 40 g/l, respectively. at 10°c, adba reached 33.8 g/l (yield 84.5%) which was 2.5 times that at 30°c. | 2011 | 21516314 |
| enhancement of microbial biodesulfurization via genetic engineering and adaptive evolution. | in previous work from our laboratories a synthetic gene encoding a peptide ("sulpeptide 1" or "s1") with a high proportion of methionine and cysteine residues had been designed to act as a sulfur sink and was inserted into the dsz (desulfurization) operon of rhodococcus erythropolis igts8. in the work described here this construct (dszas1bc) and the intact dsz operon (dszabc) cloned into vector presx under control of the (rhodococcus) kstd promoter were transformed into the desulfurization-negat ... | 2017 | 28060828 |
| classification of strain ccm 4446t as rhodococcus degradans sp. nov. | strain ccm 4446t, with notable biodegradation capabilities, was investigated in this study in order to elucidate its taxonomic position. chemotaxonomic analyses of quinones, polar lipids, mycolic acids, polyamines and the diamino acid of the cell-wall peptidoglycan corresponded with characteristics of the genus rhodococcus. phylogenetic analysis, based on the 16s rrna gene sequence, assigned strain ccm 4446t to the genus rhodococcus and placed it in the rhodococcus erythropolis 16s rrna gene cla ... | 2015 | 26385412 |
| draft genome sequence of the piezotolerant and crude oil-degrading bacterium rhodococcus qingshengii strain tuhh-12. | we report here the draft genome sequence of rhodococcus qingshengii strain tuhh-12. the ability of this piezotolerant bacterium to grow on crude oil and tetracosane as sole carbon sources at 150 × 10(5) pa makes it useful in studies of hydrocarbon degradation under simulated deep-sea conditions. | 2015 | 25858843 |
| effect of high pressure on hydrocarbon-degrading bacteria. | the blowout of the deepwater horizon in the gulf of mexico in 2010 occurred at a depth of 1500 m, corresponding to a hydrostatic pressure of 15 mpa. up to now, knowledge about the impact of high pressure on oil-degrading bacteria has been scarce. to investigate how the biodegradation of crude oil and its components is influenced by high pressures, like those in deep-sea environments, hydrocarbon degradation and growth of two model strains were studied in high-pressure reactors. the alkane-degrad ... | 2014 | 25401077 |
| effect of the anode feeding composition on the performance of a continuous-flow methane-producing microbial electrolysis cell. | a methane-producing microbial electrolysis cell (mec) was continuously fed at the anode with a synthetic solution of soluble organic compounds simulating the composition of the soluble fraction of a municipal wastewater. the mec performance was assessed at different anode potentials in terms of chemical oxygen demand (cod) removal efficiency, methane production, and energy efficiency. as a main result, about 72-80% of the removed substrate was converted into current at the anode, and about 84-86 ... | 2015 | 24994102 |
