Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicus
(BioMed Central, 2014)
BACKGROUND: Bacterial pyruvate decarboxylases (PDC) are rare. Their role in ethanol production and in bacterially
mediated ethanologenic processes has, however, ensured a continued and growing interest. PDCs from ...
High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils
(American Society for Microbiology, 2014)
The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities,
cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded ...
Selection of Clostridium spp. in biological sand filters neutralizing synthetic acid mine drainage
(Wiley, 2013)
In this study, three biological sand filter (BSF) were contaminated with a synthetic iron- [1500 mg L-1 Fe(II), 500 mg L-1 Fe(III)] and sulphate-rich (6000 mg L-1 SO2/4-) acid mine drainage (AMD) (pH = 2), for 24 days, to ...
Characterisation of campylobacter concisus strains from South Africa using amplified fragment length polymorphism (AFLP) profiling and a genomospecies-specific polymerase chain reaction (PCR) assay: Identification of novel genomospecies and correlation with clinical data
(Academic Journals, 2013)
Amplified Fragment Length Polymorphism (AFLP) profiling was used to evaluate the distribution of
phenotypically indistinguishable, but genetically distinct, among Campylobacter concisus strains from
South Africa. A Polymerase ...
A designed experiments approach to optimizing MALDI-TOF MS spectrum processing parameters enhances detection of antibiotic resistance in Campylobacter jejuni
(Frontiers Media, 2016)
MALDI-TOF MS has been utilized as a reliable and rapid tool for microbial fingerprinting at the genus and species levels. Recently, there has been keen interest in using MALDI-TOF MS beyond the genus and species levels to ...
Molecular characterization of the 16S rRNA Gene of helicobacter fennelliae isolated from stools and blood cultures from paediatric patients in South Africa
(Hindawi, 2011)
Forty strains of H. fennelliae collected from paediatric blood and stool samples over an 18 year period at a children's hospital in
Cape Town, South Africa, were amplified by PCR of the 16S rRNA. Two distinct genotypes ...
Multilocus sequence typing methods for the emerging Campylobacter species C. hyointestinalis, C. lanienae, C. sputorum, C. concisus, and C. curvus
(Frontiers Media, 2012)
Multilocus sequence typing (MLST) systems have been reported previously for multiple food - and food animal-associated Campylobacter species (e.g., C. jejuni, C. coli, C. lari, and C. fetus) to both differentiate strains ...
Micro-Eukaryotic diversity in Hypolithons from Miers Valley, Antarctica
(Multidisciplinary Digital Publishing Institute (MDPI), 2013)
The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity. However, most ...
Hypolithic and soil microbial community assembly along an aridity gradient in the Namib Desert
(Springer, 2013)
The Namib Dessert is considered the oldest desert in the world and hyperarid for the last 5 million years. However, the environmental buffering provided by quartz and other translucent rocks supports extensive hypolithic ...
Selection of diazotrophic bacterial communities in biological sand filter mesocosms used for the treatment of phenolic-laden wastewater
(Springer Verlag, 2013)
Agri effluents such as winery or olive mill waste-waters are characterized by high phenolic concentrations. These compounds are highly toxic and generally refractory to biodegradation. Biological sand filters (BSFs) represent ...
