The objective of this work was to evaluate the production of single cell protein (SCP) by five yeasts using crude glycerol as carbon source, to select the most promising strain and optimize biomass and crude protein  roduction by central composite design (CCD). Wickerhamomyces anomalus CCC32 was the most promising strain for SCP production with biomass production of 20 g L?1 and crude protein concentration of 33% after 84 h using crude glycerol 25 g L?1 , NaNO3 3.5 g L?1 and 6.5 g L?1 of urea, at 30 ?C and 150 rpm. Crude glycerol proved to be an excellent substrate option for SCP production, adding value to this residue. W. anomalus CCC32 showed promising characteristics for SCP production as fast growth and biomass production with high crude protein content.
