  • Genomics of alkaliphiles 
    Lebre, Pedro H.; Cowan, Don A. (Springer, 2019)
    Alkalinicity presents a challenge for life due to a “reversed” proton gradient that is unfavourable to many bioenergetic processes across the membranes of microorganisms. Despite this, many bacteria, archaea, and eukaryotes, ...
  • Gone with the wind : microbial communities associated with dust from emissive farmlands 
    Salawu-Rotimi, Adeola; Lebre, Pedro H.; Vos, Heleen Cornelia; Fister, Wolfgang; Kuhn, Nikolaus; Eckardt, Frank D.; Cowan, Don A. (Springer, 2021-11)
    Dust is a major vehicle for the dispersal of microorganisms across the globe. While much attention has been focused on microbial dispersal in dust plumes from major natural dust sources, very little is known about the ...
  • In silico characterization of the global Geobacillus and Parageobacillus secretome 
    Lebre, Pedro H.; Aliyu, Habibu; De Maayer, Pieter; Cowan, Don A. (BioMed Central, 2018-10-03)
    BACKGROUND : Geobacillus and Parageobacillus are two ecologically diverse thermophilic genera within the phylum Firmicutes. These taxa have long been of biotechnological interest due to their ability to secrete ...
  • Islands in the sand : are all hypolithic microbial communities the same? 
    Lebre, Pedro H.; Bottos, Eric; Makhalanyane, Thulani P.; Hogg, Ian D.; Cowan, Don A. (Oxford University Press, 2021-01)
    Hypolithic microbial communities (hypolithons) are complex assemblages of phototrophic and heterotrophic organisms associated with the ventral surfaces of translucent minerals embedded in soil surfaces. Past studies on the ...
  • Microbial nitrogen cycling in antarctic soils 
    Ortiz, Maximiliano; Bosch, Jason; Coclet, Clement; Johnson, Jenny; Lebre, Pedro H.; Salawu-Rotimi, Adeola; Vikram, Surendra; Makhalanyane, Thulani P.; Cowan, Don A. (MDPI, 2020-09)
    The Antarctic continent is widely considered to be one of the most hostile biological habitats on Earth. Despite extreme environmental conditions, the ice-free areas of the continent, which constitute some 0.44% of the ...
  • Phages actively challenge niche communities in Antarctic soils 
    Bezuidt, Keoagile Ignatius Oliver; Lebre, Pedro H.; Pierneef, Rian Ewald; Leon-Sobrino, Carlos; Adriaenssens, Evelien M.; Cowan, Don A.; Van de Peer, Yves; Makhalanyane, Thulani P. (American Society for Microbiology, 2020-05-05)
    By modulating the structure, diversity, and trophic outputs of microbial communities, phages play crucial roles in many biomes. In oligotrophic polar deserts, the effects of katabatic winds, constrained nutrients, and ...
  • Xerotolerant bacteria : surviving through a dry spell 
    Lebre, Pedro H.; De Maayer, Pieter; Cowan, Don A. (Nature Publishing Group, 2017-03)
    Water is vital for many biological processes and is essential for all living organisms. However, numerous macroorganisms and microorganisms have adapted to survive in environments in which water is scarce; such organisms ...
