De Wet, Maria Martha Marthina; Horstmann, Carla; Brink, Hendrik Gideon (Italian Association of Chemical Engineering, 2020)A lead resistant strain of Aspergillus piperis, a subgroup of A. niger with known heavy metal remediation properties, was tested for heavy metal resistance. The agar well diffusion method was used with metal solutions ...

Horstmann, Carla; Brink, Hendrik Gideon (The Italian Association of Chemical Engineering, 2019-06)The current study focused on the impact of heavy metals Zn(II) and Cu(II), regularly found in conjunction with lead in industrially polluted areas, on the Pb(II) bioprecipitation capabilities and metabolic activity of ...

Horstmann, Carla; Brink, Hendrik Gideon; Chirwa, Evans M.N. (Elsevier, 2020)The study aimed to propose a preliminary kinetic model for Pb(II) bioremoval by an industrially obtained microbial consortium. The consortium has previously been shown to be extremely effective at precipitating Pb(II) from ...

Brink, Hendrik Gideon; Horstmann, Carla; Feucht, Cherie B. (The Italian Association of Chemical Engineering, 2019)The biohydrometallurgical processing of metals have generated significant interest due to the potential for bioleaching and biological electrowinning processes to replace current energy intensive, costly, and environmentally ...

Horstmann, Carla; Brink, Hendrik Gideon (The Italian Association of Chemical Engineering, 2019)Increasing non-localised outputs of lead to the environment, in conjunction with limited raw lead supplies, have generated interest in the recovery of lead from polluted sources and areas. This study aimed to quantify the ...

Horstmann, Carla; Naidoo, Simone; Brink, Hendrik Gideon; Chirwa, Evans M.N. (Italian Association of Chemical Engineering, 2020)This study aimed to quantify the effectiveness of yeast extract, autolyzed from commercial baker’s yeast (Saccharomyces cerevisiae), as a more economical growth medium for the Pb(II) removing consortium. Three parameters ...

Brink, Hendrik Gideon; Horstmann, Carla; Peens, Jane (Springer, 2020-01)The study aimed to quantify the lead(II) bio-precipitation effectiveness, and the produced precipitate identities, of industrial consortia under aerobic and anaerobic batch conditions. The consortia were obtained from an ...
