Date issued/created: Subject and Keywords: Abstract:Strains of Y. lipolytica were flocculated in the presence of two additives either bentonite orchitosan. The effects of the flocculant doses and the pH on the yeast flocculation were studied.Stability of cell floes and their capability to citric acid production was examined in shaker flaskand stirred bioreactor cultures. The optimal flocculant doses corresponding to the maximalreduction of turbidity of cell suspensions (%RT) in the production medium were in the range of10 - 110 mg chitosan/g biomass and 30-80 mg bentonite/g biomass. Flocculated Y. lipolyticaproduced less citric acid and the volumetric citric acid productivity was lower as compared tofree cell cultures.
