Mixed cultures of different yeasts species and yeasts with filamentous fungi in the SCP production. I. Production of single cell protein by mixed cultures Candida lipolytica and Candida tropicalis.

The aim of this study was to determine the application of mixed cultures Candida lipolytica and Candida tropicalis in the SCP production. N-paraffin fraction of crude oil and individual n-alkanes C:7--C:17 and glucose were used as carbon sources. The cultures were grown on laboratory scale in shaking flasks and in a 7 1 fermentor. It was found that the mixed cultures gave about 18% higher yield of biomass than the individual cultures.
