Cloning of an alkane hydroxylase system in a long chain n-alkane- degrader Gordonia sp.
2008
Five Gram-positive GC rich n-alkane degraders were isolated from a long-term accidentally contaminated beach in Sicily and identified as one Nocardia, two Rhodococcus and two Gordonia strains (Quatrini et al., 2008 J. Appl. Microbiol. 104:251-9). All the isolates were able to grow on long and very long chain n-alkanes up to C36. Diverging alkane-hydroxylase encoding genes (alkB) were detected by PCR using degenerated primers in all the strains. Multiple sequences were obtained from the Nocardia strain while only one alkB gene was detected in Rhodococcus and Gordonia. The aim of this work is to genetically characterize the alk cluster in one of the two Gordonia strains called SoCg. Pulsed Fi…
BORDERS AND BORDER CROSSING BETWEEN ART WORLDS. Successful attempts and epic failures to enter new domains in recent British art
2016
The paper attempts to answer, whether it is possible for successful artists in one specific sector to access the domain of another artistic field at their free will. In doing so, this contribution analyses the possible existence of borders and gatekeepers between different art worlds. The aim is not just finding or defining boundaries between art fields, but rather understanding, if boundaries can be pierced through, as well as the conditions that might hinder acceptance. Moving from an art theoretical and philosophical perspective, the present paper will discuss the thesis of Pierre Bourdieu, Howard Becker, Berys Gaut and Joseph Margolis on boundary conditions in the arts. Subsequently the…
Isolation of Gram-positive n-alkane degraders from a hydrocarbon-contaminated Mediterranean shoreline.
2007
Aims: To investigate the petroleum hydrocarbon (HC)-degrading potential of indigenous micro-organisms in a sandy Mediterranean coast, accidentally contaminated with petroleum-derived HCs. Methods and Results: Using culturable methods, a population of Gram-positive n-alkane degraders was detected in the contaminated soil. Five isolates, identified as one Nocardia, two Rhodococcus and two Gordonia strains, were able to degrade medium- and long-chain n-alkanes up to C36 as assessed by growth assays and gas chromatography-mass spectrometry analysis. Diverging alkane hydroxylase-encoding genes (alkB) were detected by PCR, using degenerated primers, in all the strains; multiple sequences were obt…
Gordonia sp. SoCg alkB gene confers the ability to degrade and use n-alkanes as carbon source in Gram positive bacteria
2010
Gordonia sp. SoCg, a Gram positive strain able to grow on long chain n-alkanes1, possess a single copy of alkB2 gene, whose product is required for n-alkane hydroxylation3. An analysis of alkB flanking regions revealed five ORFs which were designed as orf1, rubA3, rubA4, rubB and alkU, according to the sequence 14 homology with that of known alk clusters3. In G. sp. SoCg the transcription of these genes was induced by long-chain and solid n-alkanes as revealed by quantitative RT-PCR, and the essential role of alkB in nalkane degradation was demonstrated by the construction of an alkB disruption mutant strain3. The SoCg alkB gene was successfully expressed in Streptomyces coelicolor M145 (M1…
