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: (Alcanivorax: Pseudomonas, 1:1), (Alcanivor...

Rhodococcus erythropolis strain R138 was isolated from the rhizosphere of Solanum tuberosum and selected for its capacity to degrade N-acyl-homoserine lactones, quorum-sensing signals used as communication molecules by the potato pathogens Pectobacterium and Dickeya. Here, we report the genome sequence of Rhodococcus erythropolis strain R138.

pAL5000 based vectors, conventionally used to transform Mycobacterium species were used in this study to transform Rhodococcus and Gordonia species. Adequate transformation efficiencies were obtained ranging between 4.5x10 3 – 2.8x10 6 . Additionally, a pAL5000 based vector with suicide function was generated. This vector was transformed into Rhodococcus, Mycobacterium and Gordonia species and ...

Here, we report the draft genome sequence of Rhodococcus sp. strain 311R, which was isolated from a site contaminated with alkanes and aromatic compounds. Strain 311R shares 90% of the genome of Rhodococcus erythropolis SK121, which is the closest related bacteria.

Protein-solvent interactions govern the behaviors of proteins isolated from extreme halophiles. In this work, we compared the solvent envelopes of two orthologous tetrameric malate dehydrogenases (MalDHs) from halophilic and non-halophilic bacteria. The crystal structure of the MalDH from the non-halophilic bacterium Chloroflexus aurantiacus (Ca MalDH) solved, de novo, at 1.7 Å resolution exhib...

The surface of polyhydroxybutyrate (PHB) storage granules in bacteria is mainly covered by proteins referred to as phasins. The layer of phasins stabilizes the granules and prevents coalescence of separated granules in the cytoplasm and unspecific binding of other proteins to the hydrophobic surfaces of the granules. Phasin PhaP1 Reu is the major surface protein of PHB granules in Ralstonia eut...

The aim of this study was to determine the expression intensity of PCNA and Ki-67 tissue antigens related to pathologically modified oral mucosa in OLR lesions, and to determine the reaction intensity of these antigens in individual clinical forms, i.e. lichen ruber planus (LRP) and lichen ruber erosivus (LRE) comparing the reaction intensity with the inflammation grade and the degree of hyperk...

Talaromyces emersonii, a thermophilic aerobic fungus, produces a complete xylan-degrading enzyme system when grown on appropriate substrates. In this paper we present the physicochemical and catalytic properties of three enzymes, xylosidase (Xyl) I (M(r) 181,000; pI 8.9), II (M(r) 131,000; pI 5.3) and III (M(r) 54,200; pI 4.2). Xyl I and II appear to be dimeric and Xyl III is a single-subunit p...
