The nutritional value of Geotrichum candidum, produced on an acid effluent from Sasol, was determined. Analysis of G. candidum revealed (on an air-dry basis) a crude protein content of 53.4% and a true protein content of 38.8% with a favourable amino acid composition (1.63% available lysine and 1.14% available methionine and cystine). The relative nutritive value (RNV) was found to be 0.505 ± 0.038 and the true protein digestibility (PTD) was 0.851 ± 0.057. The true metabolizable energy for poultry was 12.74 ± 0.26 MJ/kg dry matter.
