Molecular genetics of arsenic resistance of the biomining bacterium Acidithiobacillus ferrooxidans
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The acidophilic, chemolithoautotrophic bacterium, Acidothiobaci/lus ferrooxidans is one
of a consortium of bacteria involved in biornining, including the recovery of gold from
arsenopyrite ores. The ...
Molecular characterization of iron-oxidizing Leptospirillum strains from around the world
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: More than sixteen isolates of iron-oxidizing bacteria belonging to the genus
Leptospirillum were included in this study, with the finding that they were clearly
divisible into two major groups. Group ...
Characterisation of plasmid p31T1 isolated from Aeromonas
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: Plasmids are an integral part of the horizontal gene pool and, therefore, are the main
vectors for the spread of antibiotic and heavy metal resistance genes in the
environment. Functional and taxonomic ...
Insights into the evolution of IncQ plasmids derived form studies in pRAS3
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Two isogenic plasmids, pRAS3.1 (11,851-bp) and pRAS3.2 (11,823-bp), were identified as tetracycline resistance plasmids occurring within Aeromonas salmonicida subsp. salmonicida and atypical A. salmonicida ...
Molecular characterization of Sulfobacillus and related organisms
(Stellenbosch : Stellenbosch University, 2004-03)
ENGLISH ABSTRACT: Thirteen Sulfobacillus strains from different geographical locations and two
Alicyclobacillus strains were included in this study. These organisms proved to be
moderately thermophillic (two different ...
Analysis of the mobilization region of the broad host-range IncQ-like plasmid, pTC-F14, and its ability to interact with a related plasmid, pTF-FC2
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The 14.2 kb plasmid pTC-FI4 was isolated from the moderately thermophilic (45°-
50°C), highly acidophilic (pH 1.5 to 2.5), chemolithotrophic bacterium
Acidithiobacil/us caldus and has a replicon that ...
Comparative proteomic and genomic analysis of Flavobacterium johnsoniae-like biofilm, planktonic and agar surface-associated cells
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: Pathogenic Flavobacterium spp. cause serious disease outbreaks in a variety
of farmed fish, which lead to large economic losses in the aquaculture industry
on an annual basis. The ability of Flavobacterium ...
An investigation into the replicon of a broad host range mobilizable plasmid from the moderately thermophilic bacterium Acidithiobacillus caldus
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The moderately thermophilic (45 to 50DC), highly acidophilic (pH 1.5 to 2.5),
chemolithoautotrophic Acidithiobaci/lus caldus strain "f' was isolated from a
biooxidation process used to treat nickel ore ...
Cloning, Sequencing and Partial Characterization of the Accessory Gene Region of Plasmid pTC-F14 isolated from the Biomining Bacterium Acidithiobacillus caldus f.
(Stellenbosch : University of Stellenbosch, 2005-03)
Plasmid pTC-F14 is a 14.2kb promiscuous, broad-host range IncQ-like mobilizable plasmid isolated from Acidithiobacillus caldus f. At. caldus is a member of a consortium of bacteria (along with Acidithiobacillus ferrooxidans ...
Characterization of plasmids isolated from Aeromonas spp. obtained from South African aquaculture systems
(Stellenbosch : Stellenbosch University, 2007-03)
ENGLISH ABSTRACT: The plasmid content of 37 Aeromonas spp. isolates, obtained from South African tilapia,
trout and koi aquaculture systems, was evaluated and 17 Aeromonas spp. isolates
appeared to contain one or more ...
