  • Malic acid production by aspergillus oryzae : the role of CaCO3 
    Geyer, Monique; Onyancha, Faith M.; Nicol, Willie; Brink, Hendrik Gideon (The Italian Association of Chemical Engineering, 2018)
    This study investigated the malic acid production capability of Aspergillus oryzae NRRL 3488 with three different CaCO3 concentrations, 20 g/L, 80 g/L, and 120 g/L, used as pH buffers and CO2 supply. A black box model ...
  • Microbial lead(II) precipitation : the influence of growth substrate 
    Brink, Hendrik Gideon; Mahlangu, Zanele (The Italian Association of Chemical Engineering, 2018)
    The objective of the study was to explore the influence of various growth substrates on the removal of aqueous lead from solution. The fermentation media tested consisted of glucose- and xylose-supplemented LB-broth, ...
