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
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 ...
Efficient molecular cloning of environmental DNA from geothermal sediments
(Kluwer Academic Publishers, 2002)
An efficient and simple method for constructing an environmental library using mechanically sheared DNA obtained directly from geothermal sediments is presented. The method is based on blunt-end modification of DNA fragments ...
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 ...
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 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 ...
The Institute for Microbial Biotechnology and Metagenomics 2009
The IMBM Brochure (2009) provides a summary of the staffing, activities and outputs of the Institute for the 2009 academic year
The upper temperature for life – where do we draw the line?
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 ...
