  • Bacterial Cr(VI) reduction with internal carbon recirculation using freshwater algae as primary producers 
    Roestorff, Maria M.; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    Chromium exits naturally in two oxidation states: hexavalent chromium (Cr(VI)) and trivalent chromium (Cr(III)). Cr(VI) is carcinogenic and mutagenic to living organisms and Cr(III) is 100 times less toxic than Cr(VI). ...
  • Biological remediation of chromium (VI) in aquifer media columns 
    Mbonambi, Nondumiso C.; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019-10)
    Hexavalent chromium (Cr(VI)) is highly soluble in water, but is widely used in industrial sectors for many purposes. The effluent from these industrial activities is often released to the environment posing a threat ...
  • The Cr(VI) bioremediation potential of Chlamydomonas debaryana 
    Roestorff, Maria M.; Mbonambi, Nondumiso C.; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)
    Chromium (Cr) is an essential industrial component and has many applications in industrial manufacturing. Anthropogenic activities can lead to the release of hexavalent chromium [Cr(VI)] as well as trivalent chromium ...
  • Phenol degrading and chromium (VI) reducing biofilm system : effect of shock-loading 
    Matsena, Mpumelelo Thomas; Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    Hexavalent chromium [Cr(VI)] which are discharged together with organic pollutants in effluent streams from industry pose a health hazard to humans. The present study observed the reduction of Cr(VI) in presence of phenol ...
