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 ...
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 ...
Engineering pyruvate decarboxylase-mediated ethanol production in the thermophilic host Geobacillus thermoglucosidasius
(Springer Verlag, 2013)
This study reports the expression, purification, and kinetic characterization of a pyruvate decarboxylase (PDC) from Gluconobacter oxydans . Kinetic analyses showed the enzyme to have high affinity for pyruvate (120 μM at ...
