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 ...
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 ...
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 ...
Characterisation of the arsenic resistance genes in Bacillus sp. UWC isolated from maturing fly ash acid mine drainage neutralised solids
(Academy of Science of South Africa, 2010)
An arsenic resistant Bacillus sp. UWC was isolated from fly ash acid mine drainage (FA-AMD)
neutralised solids. A genomic library was prepared and screened in an arsenic sensitive mutant
Escherichia coli strain for the ...
