  • Musingarimi, Wicleffe; Tuffin, Marla; Cowan, Donald A. (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 ...
  • Obikezea, Kene C.; McKenzieb, Jean M.; Greenc, Ivan R.; Mugabo, Pierre (South African Chemical Institute, 2008)
    A new diterpenoid, (13S)-9 ,13 -epoxylabda-6 (19),15(14)diol dilactone (1), was isolated from Leonotis leonurus and the structure determined via NMR analysis. The compound causes significant changes in blood pressure of ...
  • Fielding, Burtram C.; Davison, Sean (Kluwer Academic Publishers, 1999-08-21)
    The polyhedrin gene (polh) was identified from the Trichoplusia ni (Tni) single capsid nuclear polyhedrosis virus (SNPV). An EcoRI fragment containing the truncated polyhedrin gene was detected by hybridization with an ...
  • Fielding, Burtram C.; Tan, Yee-Joo; Shen, Shuo; Tan, Timothy H.P.; Ooi, Eng-Eong; Lim, Seng Gee; Hong, Wanjin; Goh, Phuay-Yee (American Society for Microbiology, 2004)
    A novel coronavirus (CoV) has been identified as the etiological agent of severe acute respiratory syndrome (SARS). The SARS-CoV genome encodes the characteristic essential CoV replication and structural proteins. Additionally, ...
  • Appunni, Sathiya Susuman (Tehran University of Medical Sciences, 2012)

  • Chromista 
    Sym, Stuart D.; Maneveldt, Gavin (Wiley Online, 2011)
    The concept of chromists, at its most expansive, includes the heterokonts (stramenopiles), alveolates, rhizarians, heliozoans, telonemians, haptophytes and cryptophytes. There is mounting evidence that this grouping is not ...
  • Chromista 
    Maneveldt, Gavin; Keats, Derek (Wiley Online, 2003)
    As a group, the chromists show a diverse range of forms from tiny unicellular, flagellates to the large brown algae known as kelp. Molecular studies have confirmed the inclusion of certain organisms once considered Fungi, ...
  • Vij, Shubha; Van Heusden, Peter; Christoffels, Alan; Mbandi, Stanley K.; Mwangi, Sarah (Public Library of Science, 2016)
    We report here the ~670 Mb genome assembly of the Asian seabass (Lates calcarifer), a tropical marine teleost. We used long-read sequencing augmented by transcriptomics, optical and genetic mapping along with shared ...
  • Chamberlain, Yvonne; Norris, R.E.; Keats, Derek; Maneveldt, Gavin (Walter de Gruyter, 1995)
    A nongeniculate, crustose coralline alga (Rhodophyta, Corallinaceae) from South Africa, is found growing epiphytically on fronds of species of the geniculate genus Ampiroa. Analysis of the vegetative and reproductive ...
