Biosurfactant-assisted biodegradation of fluoranthene in a two-stage continuous stirred tank bio-reactor system using microorganism

Lutsinge Nembudani, Tshilidzi Bridget; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)

Polycyclic aromatic hydrocarbons (PAHs) are known to be resistant to environmental degradation due to their hydrophobicity which results in low solubility in water. PAHs are therefore typically less bioavailable than ...
Cr(VI) remediation with inorganic as(III) as an electron sink immobilized in a ceramic bead packed bed biofilm reactor

Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)

Ceramic bead media Biofilm Reactor Performance was evaluated for Cr(VI) reduction utilizing As(III) as electron source with mixed culture of chemoautotrophic bacteria. The inoculant used was isolated from cow dip in Tzaneen ...
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 ...
