Biodegradation of high-concentration isopropanol by a solvent-tolerant thermophile, Bacillus pallidus
(Springer Verlag, 2002)The aerobic biodegradation of high-concentration, to 24 g l –1 , 2-propanol (IPA) by a thermophilic isolate ST3, identified as Bacillus pallidus , was successfully carried out for the first time. This solvent-tolerant B. ... -
The search for the ideal biocatalyst
(Nature Publishing Group, 2002)While the use of enzymes as biocatalysts to assist in the industrial manufacture of fine chemicals and pharmaceuticals has enormous potential, application is frequently limited by evolution-led catalyst traits. The advent ... -
PCR-based detection of non-indigenous microorganisms in ‘pristine’ environments
(Elsevier, 2003)PCR-based technologies are widely employed for the detection of specific microorganisms, and may be applied to the identification of non-indigenous microorganisms in ‘pristine’ environments. For ‘pristine’ environments ... -
High 16S rDNA bacterial diversity in glacial meltwater lake sediment, Bratina Island, Antarctica
(Springer Verlag, 2003)The microbial diversity in maritime meltwater pond sediments from Bratina Island, Ross Sea, Antarctica was investigated by 16S rDNA-dependent molecular phylogeny. Investigations of the vertical distribution, phylogenetic ... -
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 ... -
Dissemination and survival of non-indigenous bacterial genomes in pristine Antarctic environments.
(Springer Verlag, 2005)Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures ... -
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 ... -
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 ... -
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 ... -
Structure of an aliphatic amidase from Geobacillus pallidus RAPc8
(International Union of Crystallography, 2007)The amidase from Geobacillus pallidus RAPc8, a moderate thermophile, is a member of the nitrilase superfamily and catalyzes the conversion of amides to the corresponding carboxylic acids and ammonia. It shows both ... -
Sequence analysis of an Archaeal virus isolated from a hypersaline lake in Inner Mongolia, China
(BioMed Central, 2007)Background: We are profoundly ignorant about the diversity of viruses that infect the domain Archaea. Less than 100 have been identified and described and very few of these have had their genomic sequences determined. ... -
The Institute for Microbial Biotechnology and Metagenomics 2009
(UWC, 2010-01)The IMBM Brochure (2009) provides a summary of the staffing, activities and outputs of the Institute for the 2009 academic year -
Real-time gesture recognition using eigenvectors
(2009)This paper discusses an implementation for gesture recognition using eigenvectors under controlled conditions. This application of eigenvector recognition is trained on a set of defined hand images. Training images are ... -
A surface acoustic wave touchscreen-type device using two transducers
(2008)Current wireless human-computer interaction devices such as wireless mice and touchscreens, by and large, incorporate a sophisticated electronic architecture. The sophistication achieves wireless capabilities but carries ... -
KernTune: Self-tuning Linux kernel performance using support vector machines
(Association for Computing Machinery, 2007)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
