The upper temperature for life – where do we draw the line?
(Elsevier, 2004)
The newly isolated hyperthermophilic archaeal strain 121
grows slowly at 121 8C and even survives short periods at
130 8C. This is another organism that grows best at
temperatures well in excess of 100 8C! We should not ...
Non-specificity of Staphylococcus generic primers
(Society for General Microbiology, 2003)
Our results allow us to conclude that there
appears to be significant conservation
between the tuf genes of Planococcus,
Planomicrobium and Staphylococcus
spp., and that although the primer set
TstaG422/TStag765 has ...
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 ...
Biodiversity: so much more than legs and leaves
(AOSIS OpenJournals, 2013)
Microorganisms inhabit virtually every possible niche on Earth, including those at the outer envelope of survival. However, the focus of most conservation authorities and ecologists is the ‘legs and leaves’ side of biology ...
16 S rDNA primers and the unbiased assessment of thermophile diversity
(Portland Press, 2004)
Our understanding of thermophile diversity is based predominantly on PCR studies of community DNA.
‘Universal’ and domain-specific rRNA gene PCR primers have historically been used for the assessment
of microbial diversity ...
Metagenomics, gene discovery and the ideal biocatalyst
(Portland Press, 2004)
With the rapid development of powerful protein evolution and enzyme-screening technologies, there is
a growing belief that optimum conditions for biotransformation processes can be established without
the constraints of ...
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 ...
Review and re-analysis of domain-specific 16S primers
(Elsevier, 2003)
The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. ...
