  • Assembling metagenomes, one community at a time 
    Van der Walt, Andries Johannes; Van Goethem, Marc W.; Ramond, Jean-Baptiste; Makhalanyane, Thulani Peter; Reva, Oleg N.; Cowan, Don A. (BioMed Central, 2017-07-10)
    BACKGROUND : Metagenomics allows unprecedented access to uncultured environmental microorganisms. The analysis of metagenomic sequences facilitates gene prediction and annotation, and enables the assembly of draft genomes, ...
  • Characterization of bacterial communities in lithobionts and soil niches from Victoria Valley, Antarctica 
    Van Goethem, Marc W.; Makhalanyane, Thulani Peter; Valverde, Angel; Cary, Stephen Craig; Cowan, Don A. (Oxford University Press, 2016-04)
    Here we provide the first exploration of microbial diversity from three distinct Victoria Valley edaphic habitats, namely lithobionts (hypoliths, endoliths) and surface soils. Using a combination of terminal restriction ...
  • Cyanobacteria and alphaproteobacteria may facilitate cooperative interactions in niche communities 
    Van Goethem, Marc W.; Makhalanyane, Thulani Peter; Cowan, Don A.; Valverde, Angel (Frontiers Research Foundation, 2017-10-25)
    Hypoliths, microbial assemblages found below translucent rocks, provide important ecosystem services in deserts. While several studies have assessed microbial diversity of hot desert hypoliths and whether these communities ...
  • Draft genome sequence of Thermoactinomyces sp. strain AS95 isolated from a Sebkha in Thamelaht, Algeria 
    Bezuidt, Keoagile Ignatius Oliver; Gomri, Mohamed A.; Pierneef, Rian Ewald; Van Goethem, Marc W.; Kharroub, Karima; Cowan, Don A.; Makhalanyane, Thulani Peter (Genomic Standards Consortium, 2016-09-09)
    The members of the genus Thermoactinomyces are known for their protein degradative capacities. Thermoactinomyces sp. strain AS95 is a Gram-positive filamentous bacterium, isolated from moderately saline water in the ...
  • Ecology and biogeochemistry of cyanobacteria in soils, permafrost, aquatic and cryptic polar habitats 
    Makhalanyane, Thulani Peter; Valverde, Angel; Velázquez, David; Gunnigle, Eoin; Van Goethem, Marc W.; Quesada, Antonio; Cowan, Don A. (Springer, 2015-04)
    Polar Regions (continental Antarctica and the Arctic) are characterized by a range of extreme environmental conditions, which impose severe pressures on biological life. Polar cold-active cyanobacteria are uniquely adapted ...
  • Environmental drivers of viral community composition in Antarctic soils identified by viromics 
    Adriaenssens, Evelien M.; Kramer, Rolf; Van Goethem, Marc W.; Makhalanyane, Thulani Peter; Hogg, Ian D.; Cowan, Don A. (BioMed Central, 2017-07-19)
    BACKGROUND : The Antarctic continent is considered the coldest and driest place on earth with simple ecosystems, devoid of higher plants. Soils in the ice-free regions of Antarctica are known to harbor a wide range ...
  • Increased temperatures alter viable microbial biomass, ammonia oxidizing bacteria and extracellular enzymatic activities in Antarctic soils 
    Barnard, Sebastian; Van Goethem, Marc W.; De Scally, S.Z. (Storme); Cowan, Don A.; Jansen van Rensburg, Peet; Claassens, Sarina; Makhalanyane, Thulani Peter (Oxford University Press, 2020-04)
    The effects of temperature on microorganisms in high latitude regions, and their possible feedbacks in response to change, are unclear. Here, we assess microbial functionality and composition in response to a substantial ...
  • Microbial diversity and functional capacity in polar soils 
    Makhalanyane, Thulani Peter; Van Goethem, Marc W.; Cowan, Don A. (Elsevier, 2016-04)
    Global change is disproportionately affecting cold environments (polar and high elevation regions), with potentially negative impacts on microbial diversity and functional processes. In most cold environments the combination ...
  • A reservoir of ‘historical’ antibiotic resistance genes in remote pristine Antarctic soils 
    Van Goethem, Marc W.; Pierneef, Rian Ewald; Bezuidt, Keoagile Ignatius Oliver; Van de Peer, Yves; Cowan, Don A.; Makhalanyane, Thulani Peter (BioMed Central, 2018-02-23)
    BACKGROUND : Soil bacteria naturally produce antibiotics as a competitive mechanism, with a concomitant evolution, and exchange by horizontal gene transfer, of a range of antibiotic resistance mechanisms. Surveys of ...
