Abstract
Upgrading of ultrafiltration permeate was carried out with the yeast Trichosporon cutaneum, a strictly respiratory organism. The mineral salts medium with urea as N-source was optimized taking into account the content of minerals of the permeate. The optimization was done by performing a X-S-diagram in continuous culture using permeate of different dilution as substrate. The growth kinetics of T. cutaneum on permeate were determined in batch cultures in a 30 1 bioreactor at unsterile conditions. The upgrading process was further tested in a 300 1 pilot plant with respect to yield, duration of growth and stability of the culture. The costs of the process were evaluated and compared to those arising from sewage disposal of the ultrafiltration permeate.
