Contents: Molasses stillage 1s a pyproduct of the sugar cane Industry in Egypt. Candida utilis and Paecilomyces variotii were used separately and in a mixed culture for treatment of this still age and biomass production. A two-steps aerobic batch process has been adopted. The distillery waste water was treated with C. utilis 1n the first step and with P.. variotii 1n the second step, which was carried out on the supernatant from the first step. The total reduction of the chemical oxygen was found to be 90%, using the mixed culture. On the other hand, the produced biomass was 22 gL-1, using the mixed culture with a productivity of about 0.5 gL-1h-1. On using C. utilis, the biomass produced was 18 gL-1 and the reduction of the COD of 45% was obtained. Meanwhile, the biomass produced was 5 gL-1 and the reduction 1n COD of 70% was achieved, using J variotii. The chemical composition and amino content as well as the biological value of the produced biomass have been given. The amino acid profiles are very similar and comparable to FAO reference protein, but with a low content of methionin and cystin and a high content of leusin, lysin and thereonin.
